An IPM Scouting Guide for Common Problems of High Tunnel and Greenhouse Vegetable Crops in Kentucky
10/17/2018 (major revision)

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. The key to effective monitoring is accurate identification. The pictures included in this guide represent the more common abiotic and biotic problems that occur on vegetable crops grown in high tunnel and greenhouse structures in Kentucky. This manual is not all-inclusive, and growers may encounter problems not included here. Please contact a local Cooperative Extension Service office for assistance. | ID-235

Collar Rot in the Tobacco Float System
3/1/2018 (major revision)

Collar rot can be found in tobacco float beds each year in Kentucky, causing a great deal of concern when it makes its appearance. Severe losses to this disease tend to be rare but can occur if care is not taken to minimize risk of disease development and reduce spread after it appears. | PPFS-AG-T-3

Managing Rhizoctonia Damping-off and Target Spot in the Float System
3/1/2018 (major revision)

Damping-off and target spot occur each year in tobacco transplant crops in Kentucky. These diseases can cause significant levels of damage to tobacco seedlings. Once considered minor problems in float beds, both have increased steadily in importance in recent years. Sound management practices and early recognition of these diseases are keys to preventing serious losses during the transplant production cycle. | PPFS-AG-T-2

Vegetable Production Guide for Commercial Growers, 2018-19
12/11/2017 (major revision)

Successful vegetable production generally requires the grower to make daily decisions regarding pest management, irrigation, and cultural practices. The most widely commercially-grown vegetables in Kentucky are included in this publication. | ID-36

2017 Fruit and Vegetable Research Report
12/5/2017 (new)

Fruit and vegetable production continues to show sustained growth in Kentucky. As the industry grows around a diverse collec-tion of marketing tactics (wholesale, farmers 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. The 2017 Fruit and Vegetable Crops re-search report includes results for 16 projects. | PR-739

Stewart's Wilt of Corn
1/1/2017 (new)

Historically, Stewart's wilt of corn has resulted in losses for corn producers. Although this disease still occurs occasionally, it has become less prevalent in recent years in Kentucky and surrounding states. Stewart's wilt has been known by other names, such as bacterial leaf blight, Stewart's leaf blight, and maize bacteriosis. | PPFS-AG-C-4

Managing Greenhouse and High Tunnel Environments to Reduce Plant Diseases
3/1/2016 (new)

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. | PPFS-GH-1

Fungicide Guide for Burley and Dark Tobacco, 2016
2/24/2016 (minor revision)

The number of fungicides that are registered for use on tobacco in Kentucky is relatively small in comparison to the large array of products available to producers of other crops. Although growers have a limited number of fungicides from which to choose, those that are available are effective against most of the major diseases of roots, stems, and foliage. | PPFS-AG-T-8

Sustainable Disease Management of Cole Crops in the Home Garden
1/1/2016 (new)

Cabbage, broccoli, cauliflower, kohlrabi, and brussel sprouts, all cole crops, are excellent plants to integrate into gardens. During wet seasons, bacterial diseases, fungal leaf spots, and downy mildew are common problems, while powdery mildew is more common during dry seasons. Bacterial diseases are also benefited by hot weather with occasional strong storms, which injure plants and spread pathogens in the garden. | PPFS-VG-23

Sustainable Disease Management of Legume Vegetable Crops in the Home Garden
1/1/2016 (new)

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-22

Sustainable Disease Management of Solanaceous Crops in the Home Garden
1/1/2016 (new)

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-21

2015 Fruit and Vegetable Research Report
12/21/2015 (new)

The 2015 Fruit and Vegetable Crops research report includes results for more than 19 field research plots and demonstration trials. This year fruit and vegetable research and demonstration trials were conducted in seven counties in Kentucky: Jefferson, Spencer, Trimble, Shelby, Caldwell, Franklin, and Fayette. | PR-706

Sustainable Disease Management of Leafy Green Crops in the Home Garden
12/1/2015 (new)

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. | PPFS-VG-20

Sustainable Disease Management of Cucurbit Crops in the Home Garden
12/1/2015 (new)

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. | PPFS-VG-19

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
