PPFS-VG-24: Biological Products for Tomato Disease Management
Erica Fealko, Emily Pfeufer | Jun. 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-22: Sustainable Disease Management of Legume Vegetable Crops in the Home Garden
Kimberly Leonberger, Emily Pfeufer | Apr. 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 | Apr. 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.
PPFS-VG-23: Sustainable Disease Management of Cole Crops in the Home Garden
Kimberly Leonberger, Emily Pfeufer | Apr. 1, 2019 (Minor Revision)
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-21: Sustainable Disease Management of Solanaceous Crops in the Home Garden
Kimberly Leonberger, Emily Pfeufer | Apr. 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-18: Blackleg and Bacterial Soft Rot of Potato
Kenny Seebold | Oct. 1, 2014 (New)
Blackleg and soft rot are bacterial diseases that cause heavy losses in Kentucky potato patches in some years. These diseases may result in missing hills when seed pieces are destroyed or the sprouts decay before they emerge from the ground. Serious rotting of tubers in potato hills and in storage can also occur.
PPFS-VG-15: Tomato Wilt Problems
Kenny Seebold | May. 1, 2014 (New)
Fusarium and Verticillium wilts are two fungal diseases that cause similar wilts in tomato. Fusarium wilt tends to be more common during warm weather, while Verticillium wilt is found more often when temperatures are cool. Both diseases share similar symptoms and can be hard to tell apart visually; laboratory tests are often needed for an accurate diagnosis.
PPFS-VG-12: Yellow Vine Decline of Cucurbits
Ric Bessin, Kenny Seebold | Aug. 1, 2011 (New)
Symptoms of yellow vine decline begin to appear approximately 2 weeks before fruit maturity. The disease may appear initially as stunting of plants and/or intense yellowing of foliage, followed by a slow decline in plant health. In some cases, a sudden collapse of vines may occur with no other symptoms. Vascular tissue (phloem) from crowns of affected plants is often discolored, appearing light brown rather than a healthy translucent green.
PPFS-VG-8: Gummy Stem Blight and Black Rot of Cucurbits
Kenny Seebold | Apr. 1, 2011 (New)
Gummy stem blight is an important disease of cucurbits in many parts of Kentucky. Under conditions favorable to disease development, commercial growers and home gardeners may experience heavy losses. This disease can occur at any point in plant growth, from seedling stage to fruit in storage. Gummy stem blight is the name given to the disease when leaves and stems are infected. Muskmelon (cantaloupe), cucumber, and watermelon are most commonly affected by this phase of the disease. Black rot refers to the same disease on fruit; it is seen less often than the foliar phase.
PPFS-VG-4: Phytophthora Blight of Cucurbits and Peppers
Kenny Seebold | Mar. 1, 2011 (New)
Under ideal conditions, Phytophthora blight is an aggressive, fast moving disease that can cause extensive losses. This disease has become increasingly problematic on cucurbits and solanaceous crops in the United States. During the past decade, Phytophthora blight has been causing significant losses in several major vegetable production areas of the U.S. In Kentucky, serious outbreaks have been reported on summer squash, winter squash, cucumbers, watermelons, and peppers.
