PR-779: 2020 Fruit and Vegetable Research Report

Doug Archbold, Win Dunwell, Bob Perry, Emily Pfeufer, Rachel Rudolph, John Snyder, John Strang | December 18, 2020 (New)

Fruit and vegetable production continues to show sustained growth in Kentucky. As the industry grows around a diverse collection of marketing tactics (wholesale, farmer markets, CSAs, and direct to restaurants) as well as various production systems, there continues to be a need for applied practical information to support the industry. Evaluation of varieties is a continuing necessity and allows us to provide the most up to date information in communications with vegetable growers. The vegetable variety trial results are the basis for updating the recommendations in our Vegetable Production Guide for Commercial Growers (ID-36).

PPFS-AG-T-7: Target Spot and Frogeye Leaf Spot of Field-grown Tobacco

Emily Pfeufer | March 31, 2020 (New)

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.

PPFS-AG-T-6: Black Shank of Tobacco

Emily Pfeufer | March 9, 2020 (New)

Black shank is one of the most important diseases of burley and dark tobacco in Kentucky. It tends to cause the greatest losses in fields with a history of black shank, during seasons with a wet to moderate early season followed by a dry August. Management is dependent on the successful combination of crop rotation, resistant varieties, and soil-directed fungicide applications.

PPFS-VG-1: Black Rot of Crucifers

David Davis, Emily Pfeufer | July 1, 2019 (Minor Revision)

Black rot, caused by the bacterial pathogen Xanthomonas campestris pv. campestris (Xcc), can be a very destructive disease of cabbage, cauliflower, and broccoli. Other susceptible crucifers include: collards, kale, Brussels sprouts, Chinese cabbage, kohlrabi, turnip, mustard, radish, and rutabaga.

PPFS-AG-T-5: Maintaining the Efficacy of Foliar Fungicides for Tobacco Disease Management

Bob Pearce, Emily Pfeufer | July 1, 2019 (Minor Revision)

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-VG-24: Biological Products for Tomato Disease Management

Erica Fealko, Emily Pfeufer | June 1, 2019 (New)

Disease management products with biologically-based active ingredients are often labeled for numerous diseases, but can vary markedly in their efficacy. This Extension publication summarizes factors to consider when choosing biological controls and data available pertaining to tomato disease management efficacy.

PPFS-VG-21: Sustainable Disease Management of Solanaceous Crops in the Home Garden

Kimberly Leonberger, Emily Pfeufer | April 1, 2019 (Minor Revision)

Solanaceous crops, including tomatoes, peppers, eggplants, and potatoes, may be the most popular garden plants, but many diseases commonly affect them. Early blight and Septoria leaf spot occur each year under even the best disease management, and bacterial spot may be spread easily under rainy conditions. A combination of approaches, such as using resistant varieties, record-keeping, cultural, and chemical management, is the best practice for minimizing vegetable garden diseases.

PPFS-VG-22: Sustainable Disease Management of Legume Vegetable Crops in the Home Garden

Kimberly Leonberger, Emily Pfeufer | April 1, 2019 (Minor Revision)

Beans and peas, both legume crops, are excellent plants to integrate into gardens for multiple reasons. These plants are affected by few of the diseases that affect other popular garden plants. Beans and peas increase nitrogen fertility where they are planted, enriching the soil for the plants that are to follow them in a rotation. These plants can be extremely productive, and are a great source of dietary fiber and, in some cases, vegetable protein.

PPFS-VG-19: Sustainable Disease Management of Cucurbit Crops in the Home Garden

Kimberly Leonberger, Emily Pfeufer | April 1, 2019 (Minor Revision)

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.
