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.

Sooty blotch and flyspeck (SBFS) is a common late summer disease complex. The resulting superficial blemishes do not cause fruit decay, but they can reduce market value for commercial produce. Infections of the waxy cuticle can also shorten storage life, as it allows for accelerated desiccation during refrigerated storage.

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.

Laurel wilt is a newly discovered fungal disease that presents a major threat to sassafras in Kentucky. The disease was first detected in the U.S. in 2003 and in southwestern Kentucky in 2019. Currently, laurel wilt is known to occur in eleven southeastern states bordered by Kentucky (north), North Carolina (east), Florida (south), and Texas (west). Research is ongoing to determine the impact and distribution of both the laurel wilt fungus and the redbay ambrosia beetle that carries it.

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.

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.

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.

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.

Cankers on woody plants can result in dieback, decline, structural failure, or plant death. Cankers form when plant pathogens enter woody tissues. Plants stressed by poor planting practices, improper maintenance, extreme weather, insect damage, mechanical damage, or other wounds are at increased risk for infection by canker causing pathogens.

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.

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.

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).

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.

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.

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.

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.

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.

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.

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.

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.

Diseases can become a significant problem in commercial and home fruit plantings, resulting in premature leaf drop, fruit decay, dieback, decline, and even plant death. When diseases do occur, it is often presumed that fungicides are the most important and effective disease management tools available. However, a good sanitation program can help reduce the need for chemical controls and can improve the effectiveness of other practices for managing disease. This often-overlooked disease management tool reduces pathogen numbers and eliminates infective propagules that cause disease.

Taxus (yew) is an evergreen shrub commonly found in Kentucky landscapes. Numerous conditions can cause these shrubs to exhibit yellowing and browning symptoms. While diseases and insect pests can result in damage, Taxus troubles are often the result of adverse growing conditions. Pinpointing the specific cause requires a thorough examination of the affected shrub, an investigation of the surrounding area, and knowledge of possible stress factors.

Black rot is the most prevalent and one of the most important grape diseases in Kentucky. While this disease can affect all young developing plant tissues above ground, fruit infections are the most destructive. Without an adequate disease management program, both home and commercial vineyards suffer significant yield losses.

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.

Damping-off can occur on any herbaceous crop grown from seed, including vegetables, ornamentals, and field crops. Seeds, seedlings, and young plants may be affected, resulting in poor stands in home gardens, greenhouses, and commercial fields. Losses to damping-off can be severe, especially when cool, wet weather prevails at seeding or seed emergence.

Thousand cankers disease (TCD) is a fatal disease of black walnut (Juglans nigra), and most recently, butternut (Juglans cinerea). The disease complex involves a fungus that is carried to trees by the walnut twig beetle, causing numerous cankers on branches and killing trees 5 to 6 years after infection. The disease complex is widespread in the western U.S., and has recently been identified in Tennessee, Pennsylvania, and Virginia.

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.
