Corn is a summer annual crop that is grown widely across Kentucky, the United States, and around the world. In the United States, field corn is grown on about 85 million acres (34 million hectares) while sweet corn is grown on about 600,000 acres (240,000 hectares) and popcorn is grown on about 200,000 acres (81,000 hectares). Most of the field corn across the United States is yellow dent corn. In Kentucky, both yellow dent corn and white dent corn are grown. Corn acres in Kentucky peaked at 3.85 million in 1917 and have been around 1.2 to 1.5 million acres since the 1970s (USDA-NASS, 2020). Most corn in Kentucky today is grown in minimum tillage or no-tillage conditions. Most corn acres are rotated with soybean or wheat and double-crop soybeans.

The 2021 Fruit and Vegetable Crops research report includes results from 12 different projects. The majority of projects were conducted on research farms, but a few were conducted on commercial farms with the assistance of grower-cooperators. We are truly grateful to the growers who invest their time, energy, and land in supporting research. Their contributions help other growers, and that is of immeasurable value. Research was conducted by University of Kentucky faculty and staff from the horticulture, plant pathology, and entomology departments, as well as faculty and staff of Kentucky State University.

Bacterial spot can result in severe damage to tomato, sweet pepper, and pimento crops. The bacterium attacks leaves, fruits, and stems causing blemishes on these plant parts. Outbreaks of leaf spotting have resulted in leaf drop and poor fruit set in the field. Defoliation due to leaf spotting can increase the incidence of sun scald on fruit. Fruit infections result in badly spotted fruit, which are of little market value. In addition, fruit injury from this disease allows entry of secondary fruit rotting organisms, causing further damage.

Tobamoviruses, including tobacco mosaic virus (TMV) and the new tomato brown rugose fruit virus (ToBRFV), can be persistent in greenhouses and other protected cropping environments. Herbaceous ornamentals, vegetables, and tobacco can be affected by tobamoviruses. Once introduced into a site, these viruses can spread rapidly, reducing plant quality and yields. Prevention and careful sanitation are important to maintaining a virus-free production environment for current and future crops.

Edema is a non-parasitic disorder which, under the right environmental conditions, can affect a wide variety of herbaceous plants. We most frequently observe this problem on indoor plants, such as dracaena, geranium and schefflera. Edema tends to be more of a problem in greenhouses, but it may also occur on plants grown in homes and offices. Field and garden grown crops, such as cabbage, may also be affected.

Diseases are a major concern for greenhouse growers and can be a key limitation to profitable plant production. Disease management in greenhouses is critical because the warm, humid environment in these structures provides optimal conditions for reproduction of many pathogens. When disease management is neglected, pathogen populations build-up and continue to increase as long as there is susceptible plant tissue available for infection and disease development. Infected plant tissue, infested soil, and pathogen inoculum (such as spores, bacterial cells, virus particles, nematode eggs) all serve as sources of pathogens that can later infect healthy plants.

Anthracnose can be a serious problem in Southern and Midwestern strawberry plantings. The disease may appear as a fruit or crown rot, both of which severely reduce plant stands and yields. Fruit rot, the most common form of anthracnose, appears as fruit begins to ripen in late spring. Crown rots, on the other hand, can develop in young plants soon after planting or when weather warms in spring.

Foliar fungicide applications occur commonly in corn to manage foliar diseases such as gray leaf spot. University of Kentucky research indicates that the most effective application timing for both foliar disease control and yield benefits is at tasseling/early silking (VT/R1). Because of the height of corn at this growth stage, these applications are typically applied aerially, with fixed wing or helicopter aircraft. However, many Kentucky fields are small, surrounded by trees or other obstacles to aircraft, meaning that fungicide application is not an option in these areas.

Corn seeds and seedlings are susceptible to infection by a number of soilborne fungi. When planted into cool, wet soils, seeds may decay before or after germination. Affected plants that survive past the seedling stage may go on to produce an ear if nodal roots develop normally, although stunting and reduced ear size can occur as a result of seedling diseases. Severely affected plants may die during stressful weather as the result of an inadequate root system.

Blackpatch is an important fungal disease of forage legumes in Kentucky. A metabolite produced by the fungus can result in slaframine toxicosis or "slobbers" in many animals. The fungal disease was first reported in Kentucky in 1933 on red clover. Most Extension literature associates blackpatch and slaframine with red clover, which is very susceptible to the disease. However, many forage legumes including alfalfa can be infected by the causal fungus.

The three most important rust diseases occurring on brambles in Kentucky are cane and leaf rust, late rust, and orange rust. The most destructive of these diseases is orange rust, which is ultimately lethal to plants. Once infected, entire plants must be removed and destroyed. In contrast, cane and leaf rust, along with late rust, are not lethal to plants and can be managed using cultural practices and fungicides. Distinguishing between these rust diseases is critical for proper management.

Dirty tools, containers, and surfaces come as no surprise to home gardeners (Figure 1). Rinsing with water to remove obvious soil or plant residues is a common practice. However, this type of basic cleaning can fail to remove microscopic plant pathogens that can remain on surfaces. Tools, containers, shoes, and surfaces should also be disinfected to remove fungal, bacterial, and viral plant pathogens to prevent transmission to healthy plants.

Long before the term "sustainable" became a household word, farmers were implementing sustainable practices in the form of Integrated Pest Management (IPM) strategies. IPM uses a combination of biological, cultural, physical, and chemical methods to reduce and/or manage pathogen and pest populations. These strategies are used to minimize environmental risks, economic costs, and health hazards. Pathogens and pests are managed (although rarely eliminated entirely) to reduce their negative impact on the crop. Scouting and monitoring for diseases, insects, weeds, and abiotic disorders helps identify potential problems before serious losses result. This is essential to the IPM approach. The key to effective monitoring is accurate identification. The images included in this guide represent the more common abiotic and biotic problems that occur in Kentucky peach plantings.

Organic mulches, such as shredded cypress and pine bark, are commonly used in commercial and home landscapes. Mulches provide numerous benefits, including conservation of soil moisture and suppression of weeds, as well as offer a visually pleasing background for landscape plantings. However, mulch is also a substrate for a diverse group of saprophytic organisms (saprobes), such as mushrooms and slime molds. While often causing alarm to gardeners unfamiliar with them, saprobes do not infect plants or cause plant diseases.

Target spot and frogeye leaf spot are the major fungal leaf spot diseases of tobacco grown in Kentucky. Burley and dark tobacco are susceptible to these leaf spot diseases; however, dark tobacco tends to be affected to a lesser extent than burley. Yield losses to target spot can exceed 50% in some years; frogeye reduces yields up to 30%, but can affect quality so severely that cured leaf may be declined. Integrated approaches, including good greenhouse production practices, crop rotation, and timely fungicide applications, will optimize management of these diseases.

Hemp is grown for fiber, grain, and cannabinoid extraction in Asia, Europe, and the Americas. Until recently, Cannabis sativa has been classified as a Schedule 1 controlled substance in the US. The Agricultural Act of 2014 (Farm Bill) allowed for reintroduction of industrial hemp under a pilot research program. Acreage increases and addition of state legislation resulted in over 78,000 acres of hemp grown in 23 states by the end of 2018. Hemp became a legal commodity under the 2018 Farm Bill, and by the end of 2019, over 500,000 licensed acres were documented across 45 states. Canada re-introduced the crop in 1998, and in 2018, almost 78,000 acres of hemp were licensed and planted.

Peach fruit diseases can cause significant losses in yield and quality in commercial and home orchards. Often these diseases go unnoticed until late in the season or at harvest. Although there are no curative treatments for infected fruit, many diseases can be prevented using cultural practices and (optional) fungicides. Accurate diagnosis, however, is critical to determine the best management practices and to prevent future losses.

Anthracnose is primarily a disease of intensely managed turfgrass, such as creeping bentgrass and annual bluegrass, on golf course putting greens. Outbreaks are generally induced by environmental conditions or cultural practices that result in stress to the turf. The anthracnose pathogen can incite a foliar blight phase or the more destructive basal rot phase.

Turgrasses under intensive management are often subject to outbreaks of infectious diseases. Good turf management practices often greatly reduce the impact of disease by promoting healthy plants that are better able to resist infections. Even under good management, however, diseases sometimes cause excessive damage to highly managed turfgrasses. The proper use of fungicides in these instances, in conjunction with good cultural practices that promote quality turf, can be an important part of an overall disease-management program.

Brown patch, also known as Rhizoctonia blight, is a common disease of turfgrass. All cultivated grasses grown in Kentucky can be affected; however, this disease is usually only destructive in tall fescue and perennial ryegrass. Fine fescues (hard fescue, creeping red fescue, chewings fescue, and sheep fescue) are all moderately susceptible to the disease. Occasionally, Kentucky bluegrass lawns can be affected by brown patch, although this grass is less susceptible than others.

Tree failures, especially in urban and recreational areas can result in harm to human life and property. While this is rare, it is important to recognize that the environmental and sociological benefits provided by trees significantly outweighs the limited risks presented by trees. This is especially true when defects and species profiles that increase the potential for failure can be observed or detected. Many of these defects are associated with certain species. This is referred to as the species failure profile.

For those with a green thumb, growing plants may seem easy. However, when plant problems arise, determining the cause of these issues can be difficult. Developing the skills necessary to determine the cause of a plant problem takes experience and time. The steps involved in the diagnostic process first require analysis of information regarding the history of the symptomatic plant and the surrounding area. Plant symptoms and signs provide additional evidence to aid in determination of a possible cause.

Management of resistance to fungicides is based on alternating the use of particular modes of action, or FRAC groups, which essentially presents multiple different challenges to the fungal population. Overall, fungi that are naturally resistant to a mode of action are very rare in the environment. Challenging a population with multiple different modes of action will reduce the chance of developing widespread resistance, which will prolong the efficacy of these chemicals.

Diagnosing plant problems can be challenging. A site visit can provide the information necessary for a complete and accurate diagnosis. However, once on-site, it is important to know how to proceed. The following guidelines are intended to assist in the process of gathering pertinent information and determining a possible cause. Often abiotic conditions such as environment, mechanical damage, or living organisms like insects or wildlife may be to blame. Should the field site diagnosis be inconclusive and samples need to be submitted to the UK Plant Diagnostic Laboratories, the information gathered here can provide valuable supplementary information.

Long before the term "sustainable" became a household word, farmers were implementing sustainable practices in the form of Integrated Pest Management (IPM) strategies. IPM uses a combination of biological, cultural, physical, and chemical methods to reduce and/or manage pathogen and pest populations. These strategies are used to minimize environmental risks, economic costs, and health hazards. Pathogens and pests are managed (although rarely eliminated entirely) to reduce their negative impact on the crop. Scouting and monitoring for diseases, insects, weeds, and abiotic disorders helps identify potential problems before serious losses result. This is essential to the IPM approach. The key to effective monitoring is accurate identification. The images included in this guide represent the more common abiotic and biotic problems that occur in Kentucky grape plantings.

Hop (Humulus lupulus) is a native herbaceous plant with a perennial crown and annual climbing stems (bines). Bines are similar to vines; however, bines wind around a support structure and lack the suckers or tendrils typical of vines. Hop crowns can survive for 25 years or more; however, the fast growing bines die back to the ground each winter. Bines can reach a height of 15 to 30 feet in a single growing season. Hops are valued for their female cones, which contain the resins and essential oils used to provide the distinctive flavor, aroma and bitterness to beer.

Bamboo is the general name used for a number of perennial, woody-stemmed grasses. Native cane (Arundinaria gigantea), which is commonly referred to as river cane, grows naturally in Kentucky and throughout much of the Southeast. It is one of three bamboo species native to North America. There are more than a hundred introduced species that can be grown in the U.S., with growth habits ranging from low-growing groundcovers to full-sized trees that reach a height of over 30 feet at maturity. Bamboos are well known for their vigorous growth and variety of uses.

Diseases in home gardens, orchards, and landscapes do not always cause total losses, but they can be serious problems if left unmanaged. As a rule, chemicals are not recommended as the only means of disease control for homeowners. Cultural practices such as sanitation, irrigation management, attention to plant health, rotation, and selection of disease-resistant varieties are usually enough to control diseases. Chemicals may be required, though, and should be used as a supplement to good management practices.

Cucurbit vining crops include cucumbers, watermelons, cantaloupe, pumpkins, zucchini, and summer and winter squashes, and can be highly productive plants in small gardens. During wet summers, downy mildew and fungal leaf spot diseases tend to occur, while in drier summers, powdery mildew is the most common disease. Gardens with cucumber beetle pressure are much more likely to have plants affected by bacterial wilt, since striped and spotted cucumber beetles can carry the bacterial wilt pathogen.

Leafy greens are great garden plants as a result of their short seasons, ease of growing, and ability to be succession planted. In wet summers, bacterial diseases, fungal leaf spots, and downy mildew are common problems, while powdery mildew is more common during dry summers. Bacterial diseases are also benefited by hot weather with occasional strong storms, which injure plants and spread pathogens in the garden. Lettuce drop, caused by the Sclerotinia fungus, can become a multi-year problem and may spread to different families of plants.

Over the past 40 years Kentucky growers have produced apples (Malus domestica) using free-standing trees in low to medium density plantings. Today's high density orchards have closely planted trees on dwarfing rootstocks requiring permanent support structures. Earlier production, quicker returns on the investment, and improved fruit quality are just a few of the many benefits of the new high-density systems.

Sod production involves growing a solid stand of high quality turfgrass and then harvesting the grass along with roots and a thin layer of topsoil. Many sod producers also transport and install the sod. The primary markets for sod are landscapers and building contractors. Sod is used in parks, golf courses, athletic fields, schools, garden centers, home lawns, road construction sites, commercial properties, and cemeteries. The 2014 USDA Census of Horticultural Specialties reported slightly less than 1,000 acres of sod harvested in Kentucky. The value of sod sales in Kentucky was split almost evenly between wholesale and retail sales.

Numerous plant diseases impact fruit crops throughout Kentucky. Factors such as plant growth stage, as well as rainfall, temperature, and other weather conditions, can be used to determine risk for plant disease. Prediction models are critical tools for growers, as they allow for protective management strategies to be deployed when disease risk is high. Use of these models can provide growers with cost savings, as unnecessary chemical applications are eliminated when risk of infection is low.

The peach (Prunus persica), which originated in China, is a member of the rose family. In the past, commercial peach production in Kentucky has been profitable only in western counties, in southern counties, and in areas along the Ohio River. However, over the past 15 years as winters have become warmer, peach growers are also doing well in areas west of the mountains, as long as good sites that avoid late spring frosts are selected.

Long before the term "sustainable" became a household word, farmers were implementing sustainable practices in the form of Integrated Pest Management (IPM) strategies. IPM uses a combination of biological, cultural, physical, and chemical methods to reduce and/or manage pathogen and pest populations. These strategies are used to minimize environmental risks, economic costs, and health hazards. Pathogens and pests are managed (although rarely eliminated entirely) to reduce their negative impact on the crop. Scouting and monitoring for diseases, insects, weeds, and abiotic disorders helps identify potential problems before serious losses result. This is essential to the IPM approach. The key to effective monitoring is accurate identification. The images included in this guide represent the more common abiotic and biotic problems that occur in Kentucky blackberry and raspberry plantings.

Diplodia leaf streak of corn is a disease that has become more prevalent in Kentucky in recent years. It is commonly observed in fields in western Kentucky and is easily confused with other corn foliar diseases. Small, round, dark brown-to-tan lesions are first observed on leaves. Dark concentric rings may be observed in the center of early lesions at the infection site on the leaf. These lesions expand lengthwise in long streaks from the infection point and form elongated elliptical lesions. In severe cases, lesions can coalesce to blight large areas of affected leaves.

Boxwood blight is a disease of boxwood (Buxus spp.), causing rapid defoliation and plant dieback. The fungal disease is particularly devastating to American boxwood cultivars, which can defoliate within a week and die within one growing season. Plants are eventually weakened by repeated defoliation and dieback, and resulting plant stress and consequent colonization by secondary invaders result in plant death.

The terms "sweet potato" and "yam" are often used interchangeably; however, they are actually two entirely different crops. Only sweet potatoes (Ipomoea batatas) are grown in the U.S.; yams (Dioscorea spp.) are grown in the Caribbean and many other tropical areas. The most profitable marketing opportunities for sweet potatoes in Kentucky are through local fresh markets, such as farmers markets, direct delivery and CSA, and on-farm stands. Producers also market through local wholesale channels, selling directly from the farm to restaurants, grocers and institutional foodservice, including schools.

Over the years, growers and county extension agents have inquired about a number of different small fruits, questioning if these crops could be grown in Kentucky. A few of these crops have potential, while many others are either completely unsuitable for production here or they are unreliable from year to year. This profile discusses some of the pros and cons of producing this latter group of small fruit. The purpose is to communicate the reasons these unique fruits are not generally recommended for commercial production in the Commonwealth.

Blackberries (Rubus spp.) are included in the group of small fruits generally referred to as 'brambles' or 'caneberries.' They have perennial crowns and roots. Most blackberry types produce canes the first season (primocanes) that do not bear fruit. The following year these are called floricanes, and bear fruit and then die naturally after harvest. Primocane-fruiting blackberries are an exception. They produce fruit on the primocanes in late summer and fall and again on these same canes (floricanes) the following July and early August before dying. With favorable growing conditions, brambles may produce for 12 or more years. Blackberries are grouped according to their growth habit: erect, semi-erect or trailing. Erect (thorny and thornless) and semi-erect (thornless) blackberries grow and yield well in most parts of the state. The trailing types are not recommended for commercial production in Kentucky due to their lack of winter hardiness. Primocane-fruiting thorny and thornless blackberries also do well in Kentucky; however, hot summers substantially reduce the primocane crop because a week of temperatures above 85 degrees F causes flowers to abort.

Greenhouse tomato production has increased in recent years, responding to consumer demand for year-round fresh produce and advances in greenhouse vegetable production practices. However, of all the greenhouse crops, tomatoes (Lycopersicon esculentum) are the most complicated to grow because they require the most management, the most labor, and the most light. A grower must be committed to meeting the daily demands of production to be successful. Prospective growers need to get as much information as they can about all aspects of greenhouse production before beginning this enterprise.

Hot peppers, also known as chili (or chile) peppers, owe most of their "heat" or pungency to a chemical substance called capsaicin. This chemical is concentrated in the cross walls of the fruit and around the developing seeds. Chili peppers can be mild to fiery hot, depending on the amount of capsaicin present. The amount of capsaicin in peppers is measured in Scoville Heat Units (SHU). Currently, the hottest pepper is considered to be the 'Carolina Reaper' which has 2.2 million SHUs. A combination of genetics and environment are responsible for the amount of heat in hot peppers. Peppers that do not contain capsaicin, such as bell peppers (0 SHUs), are considered "sweet." In addition to the hot types, other specialty peppers include sweet varieties of unusual shape, size and/or color.

During spring, several leaf spotting diseases--including Leptosphaerulina (Lepto) leaf spot and spring black stem/leaf spot--are common in alfalfa. Leaf spotting diseases result in distinct round to elongated spots that sometimes have a dark margin. Very wet weather in spring and early summer favor activity of leaf spotting diseases in first and second cuttings. Wet and humid weather during summer favor other leaf spotting and blighting diseases. All leaf spots and blights weaken plants, but alfalfa often outgrows the damage in later cuttings. Maintain a regular cutting schedule, cutting at 30- to 35-day intervals.

High tunnels, also known as hoop houses, are simple polyethylene-covered unheated structures that typically do not use fans for ventilation. Tunnels can be covered with one or two sheets of plastic; those covered with two have an air layer in between, thus offering better insulation and, consequently, more cold protection (and wind protection). High tunnels are used to extend the growing season earlier into spring and later into fall. Determinate and indeterminate tomatoes (Lycopersicon esculentum) can be successfully grown in this production system, yielding a potentially profitable "out of season."

The cucumber (Cucumus sativus) is a warm-season vining crop in the Cucurbit family. Cucumbers suitable for immediate consumption are referred to as "slicers," while those for processing are "picklers." Although there once was a large pickling cucumber industry in Kentucky, nearly all cucumbers grown commercially in the state are now for fresh market consumption.

Catnip (Nepeta cataria), best known as a stimulant for cats, is a perennial herb in the mint family (Labiatae). Cats, both domestic and wild, are attracted to catnip mainly due to a compound known as nepatalactone present in plant tissues. In addition, catnip has several properties beneficial to humans. Once used as a folk remedy for a wide variety of medical problems, today catnip's essential oils are used in a number of pharmaceutical products and dietary supplements. For example, catnip contains thymol, a compound that can be used as antiseptic. Additionally, catnip extract has a mild anti-spasmodic effect that reduces muscle cramps. Leaves and stems are used in herbal tea mixtures and as flavorings in foods. Researchers have also found that catnip contains several chemicals (citronella, citral, carvacrol, and pulegone) that repel insects; thymol has fungicidal properties.

The American or common persimmon, Diospyros virginiana, is a slow-growing, moderately sized tree native to Kentucky. Fruit are about 1 to 2 inches in diameter. Unripe fruit, which are high in tannins, have an undesirable astringent taste. Fully ripened fruit, which are golden orange to reddish and occasionally blue in color, are very sweet. Cultivated varieties may have improved quality and lose their astringency earlier in the fall.

Volutella blight (also called Pseudonectria canker) is the most common disease of boxwood in Kentucky landscapes and nurseries. This disease is caused by an opportunistic fungal pathogen that attacks leaves and stems of damaged or stressed plants. Winter injury, poor vigor, and stem wounds increase risk for Volutella blight. All species and cultivars of boxwood are susceptible.

Heirloom vegetables are vintage varieties that have been preserved by passing seed down from generation to generation. These varieties are generally 50 to 100 years old, although many are much older. All heirlooms are open-pollinated and usually breed true-to-type. Heirlooms were often selected for flavor potential and eating quality before vegetable breeding emphasized hybrid varieties bred for uniformity in size, shape and ripening, as well as for durability in shipping

The garden mum (Chrysanthemum spp.) is a popular herbaceous perennial flowering plant that is commonly grown for fall sales. While also referred to as 'hardy mums,' their actual hardiness outdoors (that is, their ability to survive the winter) can vary by cultivar, time of planting, and environmental conditions. Garden mums are generally container-grown in Kentucky, either in a greenhouse or outdoors in connection with a greenhouse business; there is also some field production in the state.

High tunnels and other season extension techniques allow producers to extend the time period over which cash flows are generated from produce crops. High tunnel production is expanding to supply the increasing demand for locally grown produce, as well as policy and grant programs favoring high tunnel production. High tunnel production of leafy greens and herbs can also enable producers to market products at higher prices, before the start of a traditional local season. High tunnel leafy greens and herbs are typically added by producers already selling through direct markets: farmers markets, CSAs (community supported agriculture programs), and direct to local restaurants and groceries.

Propagation nurseries produce pre-finished plant material (liners), such as ornamental trees, shrubs, and grasses, fruit trees, and annual and perennial flowers. Plants are propagated either by seed or by vegetative means, such as by cuttings, grafting, or tissue culture. Some nurseries specialize in growing and selling pre-finished plants to other growers, making propagation their sole business. However, some wholesale nursery operations have their own propagation areas where plants are produced for in-house use.

"Leafy greens" or "greens" are broad terms used for a number of vegetable crops with edible leaves. Plants in this group belong to several unrelated taxonomic plant families that includes Brassicaceae, Chenopodiaceae, and Asteraceae. Greens are cool-season crops that are planted in early spring or late summer/fall in Kentucky. High tunnels and similar structures can be used to extend the season into winter; however, extreme summer temperatures make year-round production in Kentucky a challenge.

Herbaceous landscape ornamentals can succumb to various adverse factors, including infectious and non-infectious diseases. Infectious diseases are caused by microorganisms, such as fungi, fungus-like water molds, bacteria, nematodes, viruses, and phytoplasmas. Abiotic or non-infectious diseases may be attributed to unfavorable growing conditions, which can include nutritional deficiencies, improper soil pH, extreme temperatures, excessive soil moisture, or drought. In order to determine the proper course of action for treatment, it is essential to accurately identify the specific cause(s).

Juneberry (Amelanchier spp.), also known as serviceberry, is a small multiple-stemmed tree or shrub that bears edible fruit. This genus includes saskatoons (Amelanchier alnifolia), which are grown commercially for fruit production in Canada and the North Central U.S. Unfortunately, saskatoons are not considered winter hardy in Kentucky and have serious leaf spot problems in this region. Most other species of Amelanchier are cultivated for use in landscape plantings; however, several of these ornamental cultivars show potential for fruit production. Among these are the Allegheny serviceberry (A. laevis) and hybrids (Amelanchier x grandiflora), which are hardy and have good leaf spot resistance in Kentucky

The container nursery business involves the production and marketing of ornamental trees and shrubs, fruit trees, and perennial flowers grown in aboveground containers. This production method has helped revolutionize the nursery business in the last few decades. Some of the advantages of container production include: less acreage required for production, handling convenience, and a nearly year-round harvest and planting season.

Field nurseries are the traditional method of producing and marketing ornamental trees, shrubs, fruit trees, and perennial flowers. Until the mid 1900s nearly all nursery crops were produced in the field. Even with the advent of aboveground container and pot-in-pot production, field nurseries are still widely used. Some of the advantages of field production over other production methods include: less maintenance and labor requirements during the growing period, ability of plants to overwinter in the field without additional protective measures, and lower start-up costs. In Kentucky, most field-grown trees and shrubs are sold as balled-and-burlapped (B&B), meaning that the soil surrounding the plant's root system is dug with the plant and wrapped in burlap.

Onions (Allium cepa) are a cool-season biennial crop typically grown as an annual. Dry bulb onions are harvested after the leaves have died back and the bulbs have fully matured. Green bunching onions are harvested while the leaves are still green and before the bulbs have developed. The terms 'scallion' and 'spring onion' are sometimes incorrectly used interchangeably for green onions. Scallions are onions that completely lack bulb formation, while spring onions have bulbs somewhat more developed than green onions.

Baby (petite, miniature, mini) vegetables are smaller versions of full-sized produce. Many baby vegetables are simply standard cultivars that are harvested at an immature stage (e.g. baby corn), while others are cultivars that have been genetically developed to produce miniature vegetables (e.g. cherry tomatoes). Smaller vegetables produced from secondary buds after the initial full-sized crop has been harvested can also be sold as baby vegetables (e.g. broccoli).

Most of the tall fescue growing in Kentucky is colonized by the tall fescue endophyte, a fungus which causes disorders in livestock that feed on the infected grass. The animal disease syndrome is called fescue toxicosis, which some researchers estimate may cost Kentucky producers over $200 million yearly. This problem can be greatly reduced by identifying the infected fields and replacing them with endophyte-free or novel endophyte tall fescue varieties or by managing them in a way to minimize the impact of the endophyte on herd productivity. One of the simplest ways to reduce toxicity symptoms in cattle is add red and white clover to existing tall fescue stands.

The most highly prized gourmet mushrooms in the world are edible mycorrhizal fungi. Included in this group are truffles, chanterelles, matsutake, porcini (boletes), and morels. All of these mushrooms have complex life cycles that make them difficult to produce artificially. Despite the risk and challenges, however, many have attempted to cultivate these valuable culinary delicacies. To date, only truffles are currently in widespread commercial production; they will be the main focus of this profile. The artificial production of other fungi in this group will be discussed briefly.

Integrated Pest Management (IPM) uses a combination of biological, cultural, physical, and chemical methods to reduce and/or manage pest populations. These strategies are used to minimize environmental risks, economic costs, and health hazards. Pests are managed (although rarely eliminated entirely) to reduce their negative impact on the crop. Scouting and monitoring diseases, insects, weeds, and abiotic disorders helps identify potential problems before serious losses result. This is essential to the IPM approach. The key to effective monitoring is accurate identification. The pictures included in this guide represent the more common abiotic and biotic problems that occur in Kentucky strawberry plantings.

There is a growing demand for ethnic fruits, vegetables, and herbs, particularly in larger cities. One obvious reason for this is the increased ethnic diversity of these areas. Many ethnic groups, including Hispanics, have a high per capita consumption of fresh produce. Also contributing to the increased demand for ethnic produce is a greater emphasis on healthy foods and the public's seemingly insatiable desire for variety in their diets. The increased growth of Kentucky's Hispanic population, along with these other factors, present an opportunity for local growers to develop a product mix aimed at these markets.

Many factors cause plants to exhibit poor vigor, changes in appearance, or even death. This chapter focuses on those living organisms that cause disease: fungi, water molds, bacteria, viruses, nematodes, phytoplasmas, and parasitic plants.

Greenhouse and high tunnel environments, which tend to be warm and humid, often create ideal situations for disease development. Environments favoring infection and spread of many disease pathogens include one or more of the following: high relative humidity (90% or above), free moisture (e.g., leaf wetness, wet soil), and/or warm temperature. Because diseases can cause extensive damage, their management is essential to production of high quality, marketable products. While challenging, these environments can be managed to simultaneously encourage plant growth and discourage pathogen spread.

Grain sorghum can be used for a variety of purposes including animal feed, unleavened breads, cakes, wallboard, starch, dextrose, brooms, ethanol, high quality wax, and alcoholic beverages. Grain sorghum produced in Kentucky is most commonly used for animal feed and was first grown here in the 1920s. Although acreage in Kentucky has fluctuated considerably over the years, yields have generally exceeded the national average since the 1970s, indicating that grain sorghum is an option for producers interested in diversifying grain crop operations.

Chia (Salvia hispanica) is an annual plant in the mint family that is grown commercially for its seeds, which are rich in omega-3 fatty acids. Chia seeds also provide an excellent source of soluble fiber and antioxidants. Until recently, chia seed production was only feasible in tropical and subtropical latitudes due to the long growing season required to complete seed development. While chia plants grow well in temperate climates, they require short days to flower and are normally killed by frost before seeds mature. Researchers at the University of Kentucky (UK) have been engaged in groundbreaking chia breeding research. This has resulted in patented varieties of long daylength flowering lines of chia capable of producing seed in the Commonwealth and the Midwest. After several years of research and field trials, chia is emerging as a viable commercial crop for Kentucky growers.

Mushrooms are strange and wonderful things--some are beautiful, some are ugly, some are delicious, and some are deadly. Mushroom hunting is a fun and rewarding hobby that can turn a hike through local woods into a puzzle-solving adventure. Many people are drawn to mushroom hunting and the potential to forage for food. Unfortunately, there is a dark side to mushroom foraging: poisoning. Each year, wild mushrooms lead to numerous illnesses and even a few deaths.

Anthracnose is the common name given to several fungal shade tree diseases with similar dark, irregularly-shaped leaf lesions. While they are primarily foliar diseases, damage on some hosts may extend to twigs, branches, and buds. In established trees, anthracnose usually does not cause permanent damage. However, resulting defoliation and dieback, especially if it occurs year after year, can weaken trees and make them more susceptible to environmental stresses and secondary pathogens.

"Wet feet" is the common term for a condition that affects plant species intolerant of wet growing conditions. This problem occurs when soils become saturated with water, which, in turn, displaces available oxygen. Roots require oxygen to function; when oxygen is deficient, roots suffocate. Once root damage occurs, plants decline and may eventually die. While "wet feet" is an abiotic disorder and is not caused by infectious organisms, declining root health and wet soil conditions can inhibit the ability of some plants to thrive. This also provides ideal conditions for many root and collar rot water mold pathogens, such as Phytophthora and Pythium.

Industrial hemp was widely grown in the United States from the Colonial Period until the mid-1800s. During that time, Kentucky established itself as the leading hemp producer in the U.S. After the Civil War, hemp production declined in Kentucky, as well as in other areas of the country. Production temporarily resumed as part of the war effort during World War II. However, once the war was over, acreages dwindled until U.S. production ended in 1958. However, the last couple of decades have brought a renewed interest in commercial hemp as an alternative or supplementary crop. As the pro-hemp movement has spread, a number of states, including Kentucky, have passed laws favoring its production, generally in connection with scientific, economic, and environmental research studies.

Industrial hemp (Cannabis sativa L.) is a versatile plant that can be grown for its fiber, seed, or oil. Hemp fields were once a common sight in Kentucky during the state's prominence as the leading hemp producer in the U.S. Although commercial hemp production ceased throughout North America in the late 1950s, there is currently renewed interest in growing this crop. While hemp faces significant legal obstacles due to its close relationship to the marijuana plant, there are a number of states, including Kentucky, working toward reviving the hemp industry. Section 7606 of the Agricultural Act of 2014 (the federal farm bill) authorized state departments of agriculture in states that have legalized hemp, including Kentucky, to develop pilot programs for industrial hemp research. The Kentucky Department of Agriculture has been working with universities, farmers and processors around the state since 2014 to implement pilot programs.

Wood decay leads to loss of tree vigor and vitality, resulting in decline, dieback, and structural failure. Wounds play an important part in this process since they are the primary point of entry for wood decay pathogens. While other factors may also result in decline and dieback, the presence of wounds and/or outward signs of pathogens provides confirmation that wood decay is an underlying problem. Wounds and wood decay reduce the ability of trees to support themselves.

Blueberry is considered one of the most disease-free fruit crops in Kentucky. Many of the diseases that affect blueberry result in minor damage. However, the most common disease of blueberry, Phytophthora root rot, can cause severe dieback and often results in plant death. The causal agent of blueberry root rot is Phytophthora cinnamomi, a soilborne water mold that occurs world-wide and can infect a wide range of hosts, including woody ornamentals. Under optimal conditions, the pathogen proliferates, and disease symptoms occur.

Many Kentucky vegetable and greenhouse producers are beginning to include fall chrysanthemum production in their operations. Garden mums are usually planted in June and sold in September when fall color is in demand. Production can vary in size; small scale growers may produce as few as 200 plants per season. Size of the operation influences cultural practices, as well as initial investments in important practices (e.g., surface drainage, pre-plant fungicide dips, and pre-emergent herbicides); all of which can impact disease management.

Eastern white pine (Pinus strobus) is a popular conifer in many Kentucky landscapes, although its use may be limited to loose, well-drained, pathogen-free soil. Often, needle browning is the primary symptom that alerts homeowners and nursery growers of health problems. In Kentucky, brown needles on white pine are often caused by one of the following three conditions: white pine decline, white pine root decline (Procerum root rot), or Phytophthora root rot.

All crop plants produced in Kentucky have the potential to become diseased under certain conditions. Diseases of crops can affect yield and/or quality of the harvested commodity, which can impact profitability and increase the risks of farming. A plant is diseased when it is affected by some agent that interferes with its normal development. Some disorders are caused by noninfectious factors, such as temperature extremes or nutrient deficiencies. However, this publication focuses on diseases caused by infectious microorganisms.

Long before the term "sustainable" became a household word, farmers were implementing sustainable practices in the form of Integrated Pest Management (IPM) strategies. IPM uses a combination of biological, cultural, physical, and chemical methods to reduce and/or manage pest populations. These strategies are used to minimize environmental risks, economic costs, and health hazards. Pests are "managed" (but rarely eliminated entirely) to reduce their negative impact on the crop. Scouting and monitoring diseases, insects, weeds, and abiotic disorders in order to identify potential problems before they result in serious losses is essential to the IPM approach. Proper identification is essential to determining the proper course of action. The pictures included in this guide represent some common pests or problems that growers may encounter during bean and pea production in Kentucky. This manual is not all-inclusive, and growers may encounter a problem that is not included here. Please contact your county Extension service for assistance.

Incorporating hanging baskets in with bedding plant production enables growers to generate income from otherwise unused space above benches and in walkways. Hanging baskets can fetch a higher price (on a per plant basis) than small pots and can, therefore, enhance the profitability of greenhouse bedding plant operations. In some cases, growers may devote whole greenhouses or sections of greenhouses to hanging basket production.

Although some of the early resistant varieties lagged behind susceptible varieties in yield, newer resistant varieties adapted for use in Kentucky do not suffer the same yield penalty. In fact, in the absence of SCN, it is common for modern SCN-resistant varieties to out-yield the best susceptible varieties in university research trials.

Most people do not realize the environmental benefits of lawns. Lawns are known to cool the air, reduce soil erosion, remove dust and pollutants (including CO2) from the air, reduce run-off of water and pollutants, create oxygen for humans, and improve soils over time by supplying organic matter. Lawns are also important aesthetically and have been shown to improve human well-being. However, to be 100 percent environmentally friendly, we could never fertilize or water our lawns and only mow with a self-propelled reel mower. Or, we could get rid of our lawn altogether. Neither of these options is particularly appealing for most people. We can, however, have a high quality lawn and reduce our impact on the environment by doing some very simple things at the right times of the year. The following guide will walk you through a series of steps that are important for keeping your lawn looking thick and healthy and at the same time reducing pests and the need for chemicals and other inputs.

Woody plant stress has many causes that might ultimately lead to plant decline. Tree and shrub degeneration is often referred to as a "complex," meaning the condition is usually caused by multiple factors. Typically, one or more primary stresses cause deterioration of plant health, followed by secondary pathogens and/or insects that further decline or destroy plants. Determining causes of decline requires careful examination of plants and growing sites, as well as knowledge of site history. Nevertheless, diagnoses may be difficult, as the original cause(s) of plant stress may be obscure or no longer present. Some of the most common plant stresses are addressed in this publication. A wider range of possible causes of plant stress and decline should be considered during evaluation of woody plant material.

Pattern, frequency, and amounts of rainfall are important components to plant health. Water is an essential plant component, making up 70 percent to 90 percent of plant mass. During dry seasons and drought conditions, plants become stressed. Growth ceases, nutrient transport slows, and plants wilt as cells become water-deficient. Severe, long-term, or consecutive drought events may cause permanent damage.

Grapes (Vitis spp.) are suitable for either large-scale or small-scale commercial production. Typically three types of grapes are grown in Kentucky: Native American, hybrid, and European grapes. The climate in Kentucky is the limiting factor to grape production. Although American and hybrid cultivars are better suited for production in Kentucky, European (vinifera) cultivars are more desirable and potentially have the highest economic gain for grape growers and wine makers. However, vinifera cultivars are more susceptible to winter injury and diseases resulting in a lower yield, reduced fruit quality, and often vine death. Growing grapes in Kentucky can be highly successful and rewarding if the cultivars are matched to a specific site and proper production techniques are implemented.

In terms of acreage, sweet corn is the largest commercial vegetable crop grown in Kentucky. Integrated Pest Management (IPM) programs have played an important role in its production and have enabled growers to improve quality and minimize input costs. IPM uses a combination of biological, cultural, physical, and chemical methods to reduce and/or manage pest populations. These strategies are employed in such a way as to minimize environmental risks, economic costs, and health hazards. Pests are "managed" but not necessarily eliminated in order to reduce their negative impact on the crop.

The National Integrated Pest Management Network defines IPM as "a sustainable approach to managing pests by combining biological, cultural, physical and chemical tools in a way that minimizes economic, health, and environmental risks." One of the key components of IPM is to continually scout and monitor crops to identify problems before they result in significant economic losses. Proper identification of pathogens and insect pests as well as nutritional and physiologic disorders and even herbicide drift is essential to determining the proper course of action. The pictures included in this guide represent some common pests or problems that growers may encounter during apple production in Kentucky.

Tall fescue, orchardgrass, bluegrass, and timothy are the dominant forage grasses in Kentucky. They have potential for the cash hay market and for intensive grazing. Significant price premiums may be possible for high-quality hay. Timothy hay, either alone or in mixtures with alfalfa, is much desired by horse owners. Historically, timothy has been an important seed crop in Kentucky; however, at present only a small acreage of timothy is grown for seed.

Grain sorghum (Sorghum bicolor), commonly called "milo," is used primarily as a feed grain for livestock. Sorghum stubble makes excellent roughage following harvest and can be used for pasture. Grain sorghum can also be made into silage, although sorghum/sudangrass hybrids are more commonly used for this purpose.

Poinsettias (Euphorbia pulcherrima) are subtropical plants which originated in Mexico and Guatemala. In their native climate, poinsettias are small woody shrubs that may reach a height of over 10 feet. In the U.S. poinsettias are grown as indoor potted plants popular at Christmas time. While the showy bracts are suggestive of flower petals, they are really modified leaves. The actual poinsettia flowers are less conspicuous by comparison, forming a yellow to red cluster in the center of the bracts.

When trees and shrubs are moved from one growing site to another (e.g. from nursery to landscape), they endure stress. If care is taken to minimize stress through proper transplanting techniques and maintenance, plants are likely to recover rapidly and become well-established in their new sites. Unfortunately, the opposite usually occurs.

Many homeowners in Kentucky grow a variety of fruits in their garden and are rewarded for their effort. One distinct advantage homeowners have over commercial orchardists is the diverse ecosystem of the home landscape (vegetable gardens, flower and fruit plantings intermixed with turf and landscape plants). Diversity often reduces the spread of insect and disease organisms and tends to keep their populations at lower, more manageable levels.

Growers who plan to market their agricultural products as "organic" or "certified organic" must first be certified by a USDA accredited certifier. Certification, required by federal regulation, provides third party verification that the grower is complying with production standards regulated by the National Organic Program (NOP). Annual inspections and detailed record keeping are required for continuing certification. These strict regulations are meant to protect consumers by ensuring that all organic producers are adhering to the same set of uniform standards.

Sunflower is classified as either an oil type or a confection (non-oil) type, each with its own distinct market. Seeds from oil types are processed into vegetable oil or as meal in livestock feed. Most confection type seed is sold, with or without the hull, as snack foods. While either type can be packaged for birdseed, the confectionery type is grown in Kentucky for this purpose. Sunflowers are not recommended for oil crop production here.

Kenaf (Hibiscus cannabinus) is a warm season annual row crop in the same plant family as okra and cotton (Malvaceae). Kenaf plants are capable of growing to a height of 20 feet under favorable conditions; however, heights generally average 8 to 14 feet in a growing season of 4 to 5 months. The stalks consist of two kinds of fiber: an outer fiber (bast) and an inner fiber (core). The bast is comparable to softwood tree fibers, while the core is comparable to hardwood fibers. After harvest, the plant is processed to separate these fibers for various products

The soybean cyst nematode (Heterodera glycines, SCN) causes many millions of dollars worth of damage to Kentucky soybean fields each year. This occurs even though damage is mostly preventable and controls are inexpensive. This situation exists because a large number of soybean producers are unaware that cyst nematode is damaging their crops. In most cases soybean cyst nematode will cause significant yield reductions without producing any detectable symptoms in soybeans. When symptoms do occur, they are frequently thought to be associated with some other factor, such as soil compaction or low soil fertility.

Fungicides are important tools in modern crop production. Unfortunately, one of the risks of using these products is that fungi sometimes develop resistance to them. Resistance development is a concern because the products may become less effective--or even useless--for controlling resistant pathogens and pests. This is a concern for all pesticides, including fungicides, insecticides, and herbicides. This fact sheet is intended to help pesticide applicators better understand this process.

Iron deficiency is a nutritional deficit that can occur in woody and herbaceous plants in landscapes, nurseries, greenhouses, and production fields. It is most often associated with soils that have neutral or alkaline pH (pH 7.0 or above). Plants that grow best in acidic soils are particularly vulnerable to this condition. In Kentucky, iron deficiency is most commonly observed on pin oak, willow oak, azalea, rhododendron, and blueberry, but other woody plants are also susceptible.

Cole crops are important as a group, particularly when all acreage of cabbage, broccoli, cauliflower, and brussel sprouts are combined. Spring planted crops may have very different problems associated with them compared to fall crops. Integrated Pest Management (IPM) programs fill an important role in production of these crops and have enabled growers to improve quality and minimize input costs. IPM uses a combination of biological, cultural, physical, and chemical methods to reduce and/or manage pest populations. These strategies are employed in such a way as to minimize environmental risks, economic costs, and health hazards. Pests are "managed," but not necessarily eliminated, in order to reduce their negative impact on the crop.

Winter small grains, especially wheat and barley, are an important part of the typical crop rotation system of many Kentucky farmers. These crops are primarily grown for their grain; however, harvesting the straw as a secondary product can provide additional income. Harvesting straw as a secondary commodity when grown in a double crop system with soybeans also minimizes harvest residue, which helps the establishment and growth of the following soybean crop. Some growers choose to forgo the grain harvest altogether, producing high quality straw as the main commodity. Other grains, such as rye, oats, and triticale, also have potential for straw production.

U.S. producers face international competition in the livestock category; corn prices have fluctuated greatly in recent years. Expanded corn markets, as well as the emergence of more uses for corn, could help stabilize future prices. In addition to animal feed, field corn uses include industrial (sweeteners) and energy (ethanol) products

Soybean foliage is susceptible to a number of fungal and bacterial pathogens. These pathogens cause leaf spots and blights and are generally common in Kentucky; however, few fields in any given year are seriously damaged by foliar diseases. Crop rotation and weather that is unfavorable to disease typically keeps foliar diseases at low levels. Occasionally an extended period of wet and humid weather in July to early August will result in significant amounts of foliar disease and yields may be seriously affected. However, this scenario is relatively uncommon in Kentucky.

Broomcorn (Sorghum vulgare) is not actually corn, but is instead related to the sorghums used for grain and syrup (Sorghum bicolor). Broomcorn has a coarse, fibrous seed head that has been used to make various types of brooms and brushes for several hundred years. While there are still artisans creating these natural brooms today, this crop is now more commonly used to make decorative items, such as wreaths, swags, floral arrangements, baskets, and autumn displays. It takes about 60 sprays (heads) to make a broom, but wreaths and dried arrangements require only a few plants. Broomcorn is available in natural colors, as well as purple and various fall colors.

Wheat, a cereal grain in the grass family, is the fourth most valuable cash crop grown in Kentucky. Current intensive management technology has made it possible for growers to produce a high quality, high-yielding crop. Wheat production is mechanized; with the exception of scouting, little to no handwork is involved with this crop. Despite significant acreage already dedicated to wheat production, additional opportunities continue to be available to make profitable returns. Most wheat grown in the Commonwealth is soft red winter wheat (Triticum aestivum) which is used in cakes, pastries, cookies, crackers, and cereals.

However, they require a specialized niche market that may take some time to develop. Flowers intended for human consumption must be grown without pesticides, providing organic growers a production edge. Plant material obtained from most commercial florists, garden centers, and nurseries is not pesticide-free and, therefore, is NOT suitable for consumption.

Small, irregular spots on upper leaf surfaces are initially pale yellow in appearance, later becoming gray-brown with a yellowish margin. On the underside of the leaves, the spots have a gray, fuzzy appearance due to the presence of the pathogen. These fungal-like tufts are reproductive structures of the organism and their appearance is diagnostic for this disease. Symptoms frequently occur at low levels throughout the crop canopy. Early leaf spots are non-descript and are commonly confused with leaf spots and pustules caused by soybean rust.

The highly nutritious seed is grown for fresh, processed, and dried uses. Interestingly, southernpeas are not a pea at all, but a type of bean related to the yardlong bean and marble pea. This profile will only discuss its production as a vegetable crop, but southernpea is also an excellent cover crop for weed suppression and nitrogen fixation. It can also be used as livestock feed.

Fire blight is a highly destructive disease of apple and pear that can occur in commercial orchards and home plantings. Many landscape trees and shrubs in the rose family are also susceptible to this disease. Fire blight can cause severe damage in a very short period of time. Because precise conditions are needed for infection, disease appearance is erratic from year to year.

Apple scab is the most consistently serious disease of apple and flowering crabapple in Kentucky. This disease also occurs on hawthorn and mountain ash; a similar disease affects pear and pyracantha (firethorn). The most noticeable losses on apple result from reduced fruit quality and from premature drop of infected fruit. Scab also causes a general weakening of the host when leaves are shed prematurely. Summer defoliation of flowering crabapple due to scab invariably results in fewer flowers the next spring.

Phytophthora root and stem rot (PRSR), caused by Phythophthora sojae, is infrequently encountered in Kentucky. However, where it does occur, the disease can be quite destructive. Soon after planting, P. sojae can cause damping-off of germinating seeds and/or young seedlings. Severe stand loss often necessitates replanting. Alternately, this pathogen can infect and kill established plants of susceptible soybean varieties any time during the season. Varieties that have some resistance to P. sojae may be stunted, but rarely die. PRSR is primarily a problem in poorly drained fields (due to high clay content, "hard pan," and/or soil compaction) or areas of fields that are prone to flooding.

Wildcrafters who want to harvest materials outside their own property lines need to know there are laws which protect other privately owned property and public areas from unauthorized harvesting and trespassing. Poaching, the illegal taking of wild plants or animals, is a serious problem in Kentucky. Not only are there legal ramifications, but poaching is also responsible for the decline in selected native Kentucky plant species, such lady slipper orchids. Some plant species are protected by state and/or federal laws. Even plant material collected and sold from personally owned property is not without its legal restrictions.

High tunnels, also known as hoop houses, are relatively simple polyethylene-covered greenhouse-like structures built over ground beds. High tunnels can be used to extend the production season and marketing window of a wide variety of crops. They have been used in Kentucky to produce early season vegetables, cut flowers, brambles, and strawberries. High tunnels can also make it possible to produce leafy greens and herbs during the winter. Shaded, well-vented high tunnels can be used to grow some cool-season crops later into early summer.

Kentuckians have been collecting plant products from forests, meadows, and other natural habitats for generations. This practice, commonly referred to as wildcrafting, is a tradition in many areas of the state, especially Appalachia. Plant materials other than timber that are harvested from the forest are generally referred to as non-timber forest products (NTFPs) or special(ty) forest products. Although often collected for personal use, many wildcrafted materials also have commercial value and could offer a means of providing additional income.

Whether collecting for personal use or for commercial sales, wildcrafting has the potential of adversely impacting our native plant populations. While the effects of collecting NTFPs are not always as obvious as, for example, harvesting timber in logging operations, some wildcrafting activities can cause subtle but lasting damage to the forest ecology.

Brown spot, caused by the fungus Septoria glycines, is present in all soybean fields in Kentucky. In most years the disease causes little to no yield impact; however, up to 15% yield losses can occur in select environments. For example, brown sport tends to be worse where soybeans follow no-till soybeans, where early-maturing varieties are planted, and/or when fields are planted in late April. River bottom fields or fields subject to fog or morning shade are frequently impacted.

Sweetpotato (Ipomoea batatas L.) is a member of the morningglory or Convolvulaceae family. Sweetpotatoes have their origins in tropical America, with early remains having been found in Panama, Peru and Mexico. A perennial plant in their native regions, they are typically killed by frost when grown in a temperate climate. Sweetpotatoes are true roots and not tubers as is the case with the Irish Potato (Solanum tuberosum). Because they are true roots they will continue to grow and enlarge as long as the plant continues to grow.

Spelt (Triticum aestivum var. spelta) is a subspecies of wheat that is primarily used as an alternative feed grain for livestock. It is generally grown for on-farm use, often as a substitute for oats. Most of the nation's feed-grade spelt is grown in Ohio. Spelt can also be used in many of the same processed foods as soft red winter wheat (for example, pasta, high fiber cereals, and crackers). Some people with allergies to wheat are not allergic to spelt, making spelt an excellent substitute for wheat in their diets. Spelt products are available through organic and health food stores.

Peanuts (Arachis hypogaea), also referred to as groundpeas or groundnuts, are an annual herbaceous legume with an indeterminate growth habit. As these alternate names imply, this unique plant produces its fruit (peanut) below ground. Once the small yellow flowers are self-pollinated, the fertilized ovary elongates into a "peg" which grows downward and penetrates into the soil. Peanuts develop underground at the ends of the pegs. The peanut seed is referred to a kernel and the outer shell is called a pod or hull.

Canola (Brassica napus) is a genetically altered and improved version of rapeseed that was developed for its superior edible oil and high value meal. The term "canola" can only be applied to those varieties that produce less than 2 percent erucic acid. Canola oil is lower in saturated fats than any other vegetable oil, making it a popular choice among health-conscious consumers. The portion of the seed left after the oil is extracted (canola meal) is of value as feed for livestock and poultry. Canola may also be used as an annual forage. In addition, canola is being considered as a source of biodiesel fuel.

Soybean cyst nematode (SCN) is the most serious disease pest of soybean in the United States (and Kentucky) and results in an estimated $1 billion in losses annually. SCN is a microscopic roundworm (Heterodera glycines) that feeds on root of soybean and reduces its capacity to absorb water and nutrients. Yield losses of 30% or more are common where SCN-susceptible soybean varieties are grown and SCN levels are high. SCN was first discovered in Kentucky in 1957 in Fulton County but is now found in every Kentucky county in which soybean is grown commercially.

Interest in the use of foliar fungicides for corn and soybean has expanded dramatically in the U.S. over the past few years, resulting in a major change in how these crops are being produced on many farms. Until recently, foliar fungicides for soybeans and corn were reserved for seed production fields to protect seed quality in very specific circumstances or for specialty crops. Applications for the purpose of protecting crop yield were rarely economical. However, the current trend in Kentucky, as well as many other corn/soybean producing states, is towards an increased use of foliar fungicides on these crops as a means of maximizing yields.

Disease management is a key component of high-yielding wheat production. In most years, it simply is not possible to produce high wheat yields without paying attention to disease control. Most diseases are best managed through the use of multiple tactics, both proactive (e.g., crop rotation, delayed and/or staggered planting plates, use of resistant varieties of varying maturities, proper fertility, and application of seed treatment and/or foliar fungicides) and reactive (e.g., application of foliar fungicides and timely harvest). Fungicides are just one tool in the disease management arsenal; however, growers often place too much emphasis on this one tool.

Symptoms of yellow vine decline begin to appear approximately 2 weeks before fruit maturity. The disease may appear initially as stunting of plants and/or intense yellowing of foliage, followed by a slow decline in plant health. In some cases, a sudden collapse of vines may occur with no other symptoms. Vascular tissue (phloem) from crowns of affected plants is often discolored, appearing light brown rather than a healthy translucent green.

Amaranth is a versatile warm-season, broadleaf plant that can be grown as a grain, ornamental, leafy vegetable, or forage crop. In the U.S. it is grown almost exclusively for its grain, which is produced on large, brightly colored seed heads. Most grain amaranth grown in the States is Amaranthus hypochondriacus; however, A. cruentus is grown to a lesser extent. The seeds are high in lysine, fiber, and protein; low in saturated fats; and gluten-free. Amaranth can be ground into flour, popped like popcorn, or flaked like oatmeal. Because many of amaranth's uses are similar to that of cereal grasses, amaranth is often referred to as a pseudo-cereal.

A greenhouse is a "tool" that can be used to facilitate the growing of plants. Generally, the tool is fitted for the job, and not the other way around. Growers need to determine what plants will be produced before making a decision about the type of greenhouse needed to accomplish the job. Depending on the crops to be grown, a conventional greenhouse may not even be needed. Instead, a simpler structure could more economically extend the growing season into spring and fall. For example, if the primary target is an early start date for farmers markets, row covers or a high tunnel may be quite adequate to handle the job.

Kentucky soybean producers frequently ask the question "Is it advisable to treat soybean seed with fungicides?" There is no pat answer to this question because of the many variables involved. Historically, soybean has not been treated to the same extent that corn and wheat have in the U.S. There are many good reasons for this, and some of them are discussed below. However, the trend is toward greater use of fungicide seed treatment on soybean, both in Kentucky and nationally.

Kentucky wheat producers have a majority of their disease management program in place once the seed is in the ground. By that time, decisions have been made regarding the length of time since the last wheat crop, tillage method and seedbed preparation, variety selection, seed quality, seed treatment, planting date, seeding rate, seeding method, and fall fertility. Individually and collectively, these decisions play an important role in determining which diseases might develop, their severity, and their potential impact on crop yield, test weight, and grain quality. Because pre-plant and planting decisions are so important in the management of wheat diseases, you need to understand how they influence disease development.

Barley yellow dwarf (BYD) is a virus disease that can cause serious yield loss when stunted and discolored plants are widely distributed in a field. Severe losses due to BYD occur state-wide about every five years or so, but individual fields are impacted to varying degrees each year. There are many diseases that can reduce wheat yields, but in the case of BYD, most of the disease management decisions (such as field selection, tillage practices, variety, and planting date) are made by the time the seed is actually sown in the fall.

The xylem-limited bacterium Xylella fastidiosa, first associated with Pierce's disease of grapevines and alfalfa dwarf disease in 1973 (4) continues to be an economically important pathogen of several commercial crops. It also causes bacterial leaf scorch in urban shade trees such as sycamore, oaks, maples, mulberry, and elm (5). The usual course of action, in an effort to control the spread of this pathogen by insect vectors (9), is to prune out infected branches and vines or to rogue infected plants. Therefore, timely testing of suspect hosts is important.

The disease was first detected in the Continental United States in the fall of 2004. Since that time, it has caused only sporadic yield losses in the U.S., primarily in the Gulf States. However, the potential still exists for devastating losses to occur in all soybean producing areas of the U.S. should the proper combination of weather conditions come together to support significant disease development by mid-summer. Currently, the only way to avert significant yield loss caused by SBR when disease risk is high is by applying foliar fungicides.

Effective use of fungicides to control soybean rust is not very complicated. The whole idea is to wait to spray until the soybean rust risk is at least moderate, and make a fungicide application before significant infection has occurred. This means applying fungicides when plant pathologists in and around Kentucky are "sounding the alarm," but before symptoms are evident. Many soybean producers in the deep South have been using fungicides to control soybean rust since 2005 with considerable success. I believe we will have the same experience if it ever becomes necessary to apply fungicides for soybean rust in Kentucky.

"Take-all" is the common name of a root, crown, and basal stem (foot) rot that primarily affects wheat, but can also affect barley, oats, rye, as well as other grass crops and weeds. The disease has been known to destroy entire stands of wheat, thus the name. Barley, oats, rye, and other grass crops, however, have not been seriously impacted in Kentucky. Take-all is most common where susceptible crops are grown continuously without adequate rotation, or in fields where weedy grass hosts were not controlled in non-host crops, and were subsequently sown to wheat. The disease is rarely a serious problem in Kentucky due to excellent weed control practices, as well as the widespread adoption of cropping systems where wheat is produced, at most, every other year.

Occasionally, wheat leaves and spikes are invaded by the bacterium, Xanthomonas campestris pv. translucens. When leaf tissue is affected, the resulting disease is known as bacterial streak. When the bacterium invades the head, the disease is called black chaff. While this disease has primarily been a problem in the lower mid-South, it is often found in Kentucky in fields that have been impacted by strong winds with blowing soil or following a damaging freeze.

Kentucky is generally well suited for growing nut trees. Northern pecans, black walnuts, heartnuts, hickory nuts, hardy Persian walnuts (Carpathian strain), American hazelnuts, and Chinese chestnuts all grow well in the state. Although most nut trees are grown by hobbyists and backyard gardeners, several varieties appear to have potential for commercial production, particularly some of the USDA pecan selections and some Chinese chestnut varieties.

Soybean cyst nematode (SCN) exists virtually everywhere soybean is grown in Kentucky. The pest is insidious in that significant yield damage often occurs without the appearance of visible disease symptoms. This is an extremely important point because it suggests that farmers are frequently unaware that SCN is active and doing damage in a field.

The Corn and Soybean Production Calendar was developed to help producers prioritize and schedule work events in a timely fashion on the farm. Weather events and equipment breakdowns rarely follow an organized schedule. However, if other practices within the farming operation are prioritized, perhaps a producer can better address the emergencies that will occur.

In most years, Cercospora leaf blight (CLB) is a minor disease problem in Kentucky soybeans. It is one of the more common "late-season" diseases, but usually comes in too little, too late to cause damage. However, in wet, late seasons like the one we experienced in 2009, significant yield and grain/seed quality losses can occur in fields that develop severe CLB before pod fill has completed.

Historically, wheat planting in Kentucky has involved tillage. With conventional tillage practices, most residues from the previous crop are cut and buried prior to seeding wheat. No-till wheat planting eliminates tillage and reduces soil erosion, particularly on sloping soils, as well as reducing labor, machinery, and energy costs.

Hot, humid weather with occasional showers is favorable for cottony blight, caused by various Pythium species. This disease, also known as Pythium blight, can be very destructive in swards of creeping bentgrass and perennial ryegrass in a high-maintenance setting, such as golf courses, croquet courts, etc. Cottony blight can occasionally be found on other cool-season turfgrasses, though very infrequently.

Long before the term "sustainable" became a household word, farmers were implementing sustainable practices in the form of integrated pest management (IPM) strategies. IPM uses a combination of biological, cultural, physical, and chemical methods to reduce and/or manage pest populations. These strategies are used to minimize environmental risks, costs, and health hazards. Pests are managed to reduce their negative impact on the crop, although pests are rarely eliminated.

Crown rots are chronic disease problems of alfalfa throughout the world. Crown rots cause loss of stand and forage yield in several ways. If the crowns are rotted severely enough, infected plants will die simply by being choked off. Carbohydrates for winter survival are stored in the crown and upper taproot. By rotting this area, crown rots also make alfalfa plants more sensitive to winter kill. Some crown rot fungi produce toxins, thus weakening or even killing the plant.

Soybean Cyst Nematode (SCN; Heterodera glycines) is the most widespread and significant pest of soybean in Kentucky. SCN is managed primarily by rotating fields to non-host crops (such as corn) and using SCN-resistant varieties. However, for a variety of reasons, producers occasionally desire to plant a SCN-susceptible variety.

Alfalfa seeded during late summer or fall is susceptible to the destructive disease Sclerotinia crown and stem rot. Fall-seeded stands are particularly vulnerable to this disease because the young seedlings have not had sufficient time to develop adequate resistance before infectious spores of the pathogen are produced in late October. In contrast, spring-seeded stands are able to develop larger, more resistant crowns prior to this infectious period. Thus, spring plantings are better able to withstand an attack, should these air-borne spores be present in the field.

Rhizoctonia fungi, particularly Rhizoctonia solani, are found in most agricultural soils in Kentucky. These fungi are natural soil inhabitants that colonize and live on dead organic matter. Under the right environmental conditions, the Rhizoctonia organisms are often able to attack living plants, including alfalfa. When warm, wet conditions prevail, Rhizoctonia fungi can cause just about every conceivable type of alfalfa disease.

Downy mildew is an important disease of commercial and backyard grapes in Kentucky. This disease causes direct losses when flowers, clusters, and shoots decay and yields are reduced. Indirect losses result when premature defoliation predisposes grapevines to winter injury. It may take a vineyard several years to fully recover after severe winter injury.

Evaluating damaged corn stands and determining when to replant is often a difficult task. Survival, health, and expected yield of the current stand must be weighed against replanting costs, additional management, and expected yield of a replanted crop. The options are rarely clear-cut because damaged corn is rarely uniform throughout the field. The following information will help when making evaluations and management decisions.

Most woody landscape plants are susceptible to shoestring root rot, cause of dieback and decline in the landscape. Diagnosis of this problem requires close examination of the base of the trunk which often reveals loose or decayed bark and dead cambium. By peeling back the bark one can often observe dark brown rhizomorphs (thick strands of hyphae), resembling narrow "shoestrings."

This publication is written for those who wish to maintain their lawn with minimal inputs. Low-maintenance lawn care offers certain benefits, such as minimal pesticide use, reduced fertilizer input, less need for irrigation, and reduced mowing frequency. However, when choosing a low-maintenance approach, recognize that the lawn will not offer the same dark green, uniform sward of turf that is seen under a high-maintenance lawn-care program.

Kentucky has a long record of good grape production. As a home fruit crop or commercial crop, grapes have many benefits. Grapevines are relatively inexpensive and easy to propagate. They reach full bearing potential in four years and bear annually. The many varieties of grapes can be consumed fresh or used to make grape juice, jams, jellies, and wine. Grapes are also easy to manage. Vines are trained on trellises or arbors and easily can be sprayed using small equipment for control of insects and diseases.
