PPFS-GEN-19: Botrytis Blight

PPFS-GEN-18: Edema
Nicole Ward Gauthier, John Hartman | May. 10, 2021 (Major Revision)
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.
PPFS-GEN-17: Cleaning and Disinfecting Home Garden Tools and Equipment
Kara Back, Nicole Ward Gauthier, Kimberly Leonberger | Jun. 26, 2020 (New)
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.
PPFS-GEN-6: Mulch Mushrooms, Slime Mold, and other Saprophytes
Nikki Bell, Nicole Ward Gauthier, Cheryl Kaiser | Jun. 4, 2020 (Major Revision)
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.
PPFS-GEN-1: Crown Gall
David Embry, Nicole Ward Gauthier | Oct. 1, 2019 (Minor Revision)
Crown gall can affect a wide range of crops, including woody ornamentals, tree fruits and small fruits. Some vegetable and herbaceous ornamentals are also susceptible but these crops are less commonly affected.
PPFS-GEN-15: Considerations for Diagnosis of Ornamentals in the Landscape
Amy Aldenderfer, Adam Leonberger, Kimberly Leonberger, Nicole Ward Gauthier | Jul. 1, 2019 (Minor Revision)
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.
PPFS-GEN-8: Simplified Fungicide Guide for Backyard Fruit
Nicole Ward Gauthier | Apr. 1, 2019 (Minor Revision)
This fungicide spray guide is intended as a supplement to the more detailed spray schedule available in Disease and Insect Control Programs for Homegrown Fruit in Kentucky, Including Organic Alternatives, ID-21.
PPFS-GEN-7: Homeowner's Guide to Fungicides
Kenny Seebold, Nicole Ward Gauthier | Apr. 1, 2019 (Minor Revision)
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.
PPFS-GEN-16: Southern Blight
Carl Bradley, Emily Pfeufer, Nicole Ward Gauthier | Aug. 1, 2018 (New)
Southern blight affects hundreds of different plants, including vegetables, field crops, ornamentals, and fruit. This disease is also known as southern stem blight, basal stem rot, Sclerotium blight, crown rot, and white mold (not to be confused with Sclerotinia white mold). Depending on host plant, production system, and environmental conditions, the severity of this disease can vary from a minor problem on isolated plants to extensive damage causing significant crop losses.
