High Tunnel Tomatoes
9/5/2017 (minor revision)

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." | CCD-CP-62

8/11/2017 (minor revision)

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. | CCD-CP-50

High Tunnel Leafy Greens and Herbs
7/11/2017 (minor revision)

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. | CCD-CP-60

Propagation Nursery
6/5/2017 (minor revision)

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. | CCD-SP-8

Managing Diseases of Herbaceous Ornamentals
5/1/2017 (new)

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). | PPFS-OR-H-1

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 | CCD-CP-11

Field Nursery Production
4/17/2017 (minor revision)

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. | CCD-SP-6

Container Nursery Production
4/17/2017 (minor revision)

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. | CCD-SP-5

4/12/2017 (major revision)

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. | CCD-CP-107

Baby Vegetables
4/12/2017 (minor revision)

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). | CCD-CP-86

Baby Corn
4/12/2017 (minor revision)

Baby corn (Zea mays) is a popular Asian vegetable that can be consumed cooked or raw due to its sweet and succulent taste. Many people presume the tiny ears come from dwarf corn plants. In fact, baby corn is the immature ear of fully grown standard cultivars; ears are harvested two or three days after silk emergence, but prior to fertilization. | CCD-CP-85

Sampling for the Tall Fescue Endophyte in Pasture or Hay Stands
4/10/2017 (minor revision)

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. | PPA-30

Chemical Control of Turfgrass Diseases, 2017
4/4/2017 (major revision)

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. | PPA-1

An IPM Scouting Guide for Common Problems of Strawberry in Kentucky
11/17/2016 (new)

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. | ID-238

Ethnic Vegetables: Hispanic
9/13/2016 (minor revision)

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. | CCD-CP-97

Organic Lettuce and Leafy Greens
8/5/2016 (minor revision)

Leafy greens and lettuce, which are among the most popular fresh market vegetables grown commercially in Kentucky, have excellent potential for organic production. Organic crops are produced using integrated pest management and fertilization methods that do not include synthetic compounds. Growers producing and selling lettuce and greens with an organic label must be certified by a USDA-approved state agency (e.g. the Kentucky Department of Agriculture) or private agency, plus follow production standards regulated by the National Organic Program (NOP). | CCD-CP-109

Hop (Humulus lupulus) is an 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 and aroma to beer. | CCD-CP-80

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. | CCD-CP-26

"Wet Feet" of Ornamentals
11/1/2015 (new)

"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. | PPFS-OR-W-4

Industrial Hemp: Legal Issues
9/24/2015 (minor revision)

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. | CCD-CP-32

Industrial Hemp Production
9/23/2015 (minor revision)

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. | CCD-CP-33

Tree Wounds: Invitations to Wood Decay Fungi
9/1/2015 (new)

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. | PPFS-OR-W-1

Maintaining the Efficacy of Foliar Fungicides for Tobacco Disease Management
7/1/2015 (new)

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. | PPFS-AG-T-5

An IPM Scouting Guide for Common Problems of Legume Vegetables in Kentucky
1/30/2015 (new)

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. | ID-227

Considering the Environment in the Maintenance of Your Kentucky Lawn: A Season by Season Approach
7/30/2014 (new)

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. | ID-222

Shade Tree Decline and Related Problems
7/1/2014 (major revision)

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. | ID-50

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. | CCD-CP-7

Blackberries (Rubus spp.) are included in the group of small fruits generally referred to as 'brambles' or 'caneberries.' They have perennial crowns and roots that produce biennial canes. Most blackberry types produce canes that bear fruit the second year and then die naturally after harvest. Primocane fruiting blackberries produce canes that grow and fruit the first season (primocane) in late summer and fall and also produce fruit on these same canes (floricanes) the second season in July and early August before dying. Blackberries are grouped according to their growth habit: erect, semi-erect, and trailing. The trailing types are not recommended for commercial production in Kentucky due to their lack of winter hardiness. Erect (thorny and thornless) and semi-erect (thornless) blackberries, however, grow and yield well in most parts of the state. Primocane fruiting thorny and thornless blackberries also do well in Kentucky, however hot summers substantially reduce the primocane crop because temperatures above 85 F cause flowers to abort. With favorable growing conditions, a planting may produce for 12 or more years. | CCD-CP-4

An IPM Scouting Guide for Common Problems of Apple in Kentucky
5/7/2014 (new)

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. | ID-219

Cool-season Forage Grasses: Tall Fescue, Orchardgrass, Bluegrass, and Timothy
5/5/2014 (minor revision)

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. | CCD-CP-27

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. | CCD-CP-64

Root-knot Nematode in Commercial and Residential Crops
5/1/2014 (new)

Root-knot nematode (RKN) is a soil-dwelling microscopic roundworm. This nematode is parasitic on numerous plants, including vegetables, fruits, field crops, ornamentals, and common weeds. RKN can occur in commercial and homeowner plantings. Frequently, the nematode interacts with other plant pathogens to form a disease complex in which the resulting disease is much more severe than that caused by either component alone. Root-knot nematode is particularly serious when high populations are allowed to build up due to continuous replanting of susceptible plants on the same site. | PPFS-GEN-10

Hot Peppers and Specialty Sweet Peppers
4/15/2014 (minor revision)

Hot peppers, also known as chili (or chile) peppers, owe 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. Peppers that do not contain capsaicin, such as bell peppers, are considered "sweet". In addition to the hot types, other specialty peppers include sweet varieties of unusual shape, size and/or color. | CCD-CP-101

Sampling Soybean Fields for Soybean Cyst Nematode Analysis
1/1/2014 (minor revision)

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. | PPFS-AG-S-9

An IPM Scouting Guide for Common Problems of Cole Crops in Kentucky
7/22/2013 (new)

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. | ID-216

Greenhouse Sanitation
3/1/2013 (new)

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. | PPFS-GH-4

Downy Mildew of Soybean
9/1/2012 (minor revision)

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. | PPFS-AG-S-3

Phytophthora Root and Stem Rot of Soybean
7/1/2012 (minor revision)

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. | PPFS-AG-S-4

Wildcrafting Non-Timber Forest Products: Legal Considerations
6/28/2012 (minor revision)

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. | CCD-SP-14

Foliar Fungicide Use in Corn and Soybeans
10/1/2011 (new)

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. | PPFS-GEN-12

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. | PPFS-AG-SG-5

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. | CCD-CP-30

Turfgrass Sod Production
7/18/2011 (minor revision)

The demand for sod is highly dependent on new housing starts and industrial development. Because turfgrass is highly perishable once harvested, it cannot be shipped long distances, thus favoring local production. Most Kentucky-grown sod is marketed locally and little is either exported to or imported from neighboring states. While temporary sod shortages may occur, there is generally no consistent shortage of cultivated sod in Kentucky, indicating that current production is meeting demand. The market is extremely tight and new growers will have to produce a better quality turfgrass at a lower price in order to compete. | CCD-CP-74

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. | CCD-SP-1

Greenhouse Tomatoes
5/4/2011 (minor revision)

Greenhouse tomato production has attracted a great deal of attention in recent years. 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 in order to be successful. Prospective growers need to get as much information as they can about all aspects of greenhouse production before beginning this enterprise. | CCD-CP-57

Seed Treatment Fungicides for Soybeans: Issues to Consider
4/1/2011 (minor revision)

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. | PPFS-AG-S-12

For a variety of reasons, few Kentucky wheat producers place much emphasis on scouting their wheat diseases. Time and labor constraints (for do-it-yourselfers), the cost of hiring a crop consultant, and indifference to the need for scouting rank among the top reasons why this is the case. However, scouting is essential for those interested in managing diseases using an integrated approach. | PPFS-AG-SG-12

Preplant Decisions Greatly Impact Disease Potential in Wheat
4/1/2011 (minor revision)

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. | PPFS-AG-SG-6

Recognizing Late Blight on Tomato Seedlings
4/1/2011 (new)

Tomato seedlings that have late blight when transplanted can serve as sources of inoculum (spores) that can spread to nearby gardens and commercial plantings, so every measure should be taken to prevent these plants from making it to the field. The added threat is that sources of disease are introduced early in the tomato production season, magnifying the potential for heavy losses in seasons that favor late blight. | PPFS-VG-14

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. | PPFS-AG-SG-3

Soybean Loss Prediction Tool for Managing Soybean Rust
7/1/2010 (new)

Soybean rust (SBR), caused by the fungus, Phakopsora pachyrhizi, is a potentially devastating foliar disease of soybean. 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. | PPFS-AG-S-10

Soybean Rust Fungicide Use Guidelines
6/1/2010 (minor revision)

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. | PPFS-AG-S-23

"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. | PPFS-AG-SG-1

Poinsettia Diseases
5/1/2010 (minor revision)

Poinsettias grown through the fall months for Christmas sales are vulnerable to destructive diseases from the time the cuttings are stuck into the rooting media until they are mature and ready for sale. A number of poinsettia diseases are favored by the same environmental conditions that promote propagation, making plant material at this stage particularly vulnerable. Diseases occurring in the later stages of production can be related to management issues or cultural problems, as well as the cooler temperatures needed for finishing. Some other diseases can be problematic to poinsettias at any phase of production. And finally, a phytoplasma organism found associated with poinsettias provides evidence that some host/pathogen relationships can actually be economically beneficial. | PPFS-GH-6

Risk Factors for Sclerotinia Crown and Stem Rot in Fall-Seeded Alfalfa
12/1/2008 (minor revision)

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. | PPFS-AG-F-2

Diseases of Concern in Continuous Corn
10/1/2008 (minor revision)

Although most corn in Kentucky is planted following a rotation to other crops, individual producers are often interested in planting corn following corn. In these situations, one of the main concerns voiced by producers is increased pressure from diseases, and rightfully so. Crop rotation is one of the most fundamental disease control practices available. Rotating to other crops deprives pathogens (disease-causing microorganisms) of a food source and exposes them to "starvation." Furthermore, as infested crop residues decompose, pathogens are exposed to antagonism by native soil microbes. These mechanisms have the effect of naturally reducing the populations of many pathogens in the soil. | PPFS-AG-C-1

Southern Blight of Soybeans
10/1/2008 (minor revision)

Southern blight is a minor disease of soybeans in the United States. Although the disease can occur in plants anytime from emergence through pod fill, it most commonly occurs in isolated plants in the latter stages of reproductive development. Occasionally, southern blight develops when plants are in the early to mid-vegetative stages. When this occurs, the disease may spread rapidly down rows, resulting in serious stand losses in patches. However, even in the worst case scenario, it would be extremely rare for southern blight to cause measurable yield losses in a commercial soybean field. | PPFS-AG-S-6

This infectious disease is capable of spreading rapidly, resulting in devastating losses. It is a particularly difficult disease to manage because not only is there no cure, but the pathogen can be hard to eradicate once it has been introduced into a greenhouse, garden, or field. | PPFS-VG-6

Blossom End Rot
1/1/2008 (minor revision)

Blossom end rot is a physiological disorder (non-parasitic disease) caused by a lack of calcium (Ca) in the distal ends of developing fruit. Calcium is an essential part of the chemical "glue" that binds cells together within the fruit. When fruits are enlarging rapidly, sufficient amounts of Ca fail to reach the end of the fruit and cells then come apart. This is because Ca is not a very mobile element, so any disruption in uptake of Ca can result in a deficiency of Ca in developing fruit. | PPFS-VG-2

Replanting Options for Corn
7/27/2007 (new)

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. | AGR-195

Shoestring Root Rot: A Cause of Tree and Shrub Decline
5/1/2005 (minor revision)

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." | PPFS-OR-W-5

Raspberry Fruit Rots
7/1/2004 (minor revision)

Rainy summer and fall weather in Kentucky can provide ideal conditions for fruit decay diseases of raspberries. The most damaging are the fungal diseases gray mold (Botrytis cinerea) and soft rot, or leak (Rhizopus and Mucor spp.). Both diseases are favored by long periods of wet fruit and foliage, and by high humidity levels. During some parts of the season, fruit rots account for up to 50% loss of potential harvest, and additional losses after harvest. | PPFS-FR-S-4

A Comprehensive Guide to Corn Management in Kentucky
9/30/2001 (new)

The corn grown in Kentucky is used mainly for livestock feed and as a cash crop. As a cash crop sold from the farm, corn ranks third behind tobacco and soybeans but is the number one row crop in terms of acreage. Because the cost of producing an acre of corn is high and the value per bushel has declined in recent years, producers must manage and market their corn crop more carefully for adequate profits. The goal of this publication is to serve as a guide for corn production strategies that focus on efficient use of resources and provide the principles and practices for obtaining maximum, profitable corn yields. | ID-139

Growing Grapes in Kentucky
4/30/2000 (reprinted)

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. | ID-126
