PPFS-AG-T-5
Maintaining the Efficacy of Foliar Fungicides for Tobacco Disease Management
7/1/2019 (minor revision)

 UK Authors: Bob Pearce, Emily Pfeufer
 Departments: Plant and Soil Sciences, Plant Pathology
 Series: Tobacco Disease: Plant Pathology Factsheet (PPFS-AG-T series)
 Tags: farm crops, plant diseases, tobacco

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.

Sustainable Disease Management of Cole Crops in the Home Garden
4/1/2019 (minor revision)

 UK Authors: Kimberly Leonberger, Emily Pfeufer
 Departments: Plant Pathology
 Series: Vegetable Disease: Plant Pathology Factsheet (PPFS-VG series)
 Tags: farm crops, fruits and nuts, plant diseases

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-22
Sustainable Disease Management of Legume Vegetable Crops in the Home Garden
4/1/2019 (minor revision)

 UK Authors: Kimberly Leonberger, Emily Pfeufer
 Departments: Plant Pathology
 Series: Vegetable Disease: Plant Pathology Factsheet (PPFS-VG series)
 Tags: farm crops, fruits and nuts, plant diseases

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.

Sustainable Disease Management of Solanaceous Crops in the Home Garden
4/1/2019 (minor revision)

 UK Authors: Kimberly Leonberger, Emily Pfeufer
 Departments: Plant Pathology
 Series: Vegetable Disease: Plant Pathology Factsheet (PPFS-VG series)
 Tags: farm crops, fruits and nuts, plant diseases

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-20
Sustainable Disease Management of Leafy Green Crops in the Home Garden
4/1/2019 (minor revision)

 UK Authors: Kimberly Leonberger, Emily Pfeufer
 Departments: Plant Pathology
 Series: Vegetable Disease: Plant Pathology Factsheet (PPFS-VG series)
 Tags: farm crops, fruits and nuts, plant diseases

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.

Sustainable Disease Management of Cucurbit Crops in the Home Garden
4/1/2019 (minor revision)

 UK Authors: Kimberly Leonberger, Emily Pfeufer
 Departments: Plant Pathology
 Series: Vegetable Disease: Plant Pathology Factsheet (PPFS-VG series)
 Tags: farm crops, fruits and nuts, plant diseases

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

 UK Authors: Philip Konopka, Emily Pfeufer,
 Departments: County Extension, Plant Pathology
 Series: Greenhouse Plant Disease: Plant Pathology Factsheet (PPFS-GH series)
 Tags: plant diseases

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.
