PPFS-GH-7: Cleaning and Sanitizing Commercial Greenhouse Surfaces
Samantha Anderson, Nicole Ward Gauthier, Josh Knight, W. Garrett Owen | Aug. 3, 2020 (New)
Greenhouse and nursery sanitation practices help prevent the introduction and spread of plant diseases and pests, as well as eliminate safety hazards. In general, being proactive in maintaining a clean growing environment will often be less expensive and more effective than reacting to a disease or pest issue after it emerges.
PPFS-OR-W-28: Laurel Wilt Disease and Redbay Ambrosia Beetle
Ellen Crocker, Tyler Dreaden, Nicole Ward Gauthier, Jonathan Larson, Kimberly Leonberger | Jul. 8, 2020 (New)
Laurel wilt is a newly discovered fungal disease that presents a major threat to sassafras in Kentucky. The disease was first detected in the U.S. in 2003 and in southwestern Kentucky in 2019. Currently, laurel wilt is known to occur in eleven southeastern states bordered by Kentucky (north), North Carolina (east), Florida (south), and Texas (west). Research is ongoing to determine the impact and distribution of both the laurel wilt fungus and the redbay ambrosia beetle that carries it.
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.
ID-260: An IPM Scouting Guide for Common Problems of Peach in Kentucky
Ric Bessin, Nicole Ward Gauthier, Cheryl Kaiser, Matthew Springer, John Strang, Shawn Wright | Jun. 8, 2020 (New)
Long before the term "sustainable" became a household word, farmers were implementing sustainable practices in the form of Integrated Pest Management (IPM) strategies. IPM uses a combination of biological, cultural, physical, and chemical methods to reduce and/or manage pathogen and pest populations. These strategies are used to minimize environmental risks, economic costs, and health hazards. Pathogens and pests are managed (although rarely eliminated entirely) to reduce their negative impact on the crop. Scouting and monitoring for diseases, insects, weeds, and abiotic disorders helps identify potential problems before serious losses result. This is essential to the IPM approach. The key to effective monitoring is accurate identification. The images included in this guide represent the more common abiotic and biotic problems that occur in Kentucky peach plantings.
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-FR-S-30: Cultural Calendar for Commercial Strawberry Production
Ric Bessin, Nicole Ward Gauthier, Kimberly Leonberger, Matthew Springer, John Strang, Shawn Wright | May. 27, 2020 (New)
Inegrated pest management (IPM) includes the combination of biological, cultural, physical, and chemical tools in efforts to manage diseases and pests while minimizing risks associated with pesticides. Cultural practices are an integral part of an IPM program and should be incorporated into all commercial systems whether large or small, conventional or organic. This publication provides recommended practices at approximate growth stages and/or production periods. However, these timelines are approximate and may require adjustment for particular conditions. Growers who encounter situations that may not align with suggestions here should contact their county Extension office for assistance.
PPFS-FR-S-29: Cultural Calendar for Commercial Blueberry Production

PPFS-FR-T-27: Brown Rot of Peach
Nicole Ward Gauthier, Erica Wood | Apr. 17, 2020 (New)
Brown rot is the most devastating disease of peach in Kentucky. The disease affects both commercial and backyard orchards. Crop losses occur primarily as a result of fruit decay; however, blossom blight is also part of the disease cycle. All stone fruit (peach, nectarine, plum, and cherry) are susceptible to brown rot.
SR-112: Science of Hemp: Production and Pest Management, 2020
Bernadette Amsden, Samantha Anderson, Ric Bessin, Susan Fox, Nicole Ward Gauthier, Ross Guffey, Tom Keene, Tyler Mark, Bob Pearce, Christopher Schardl, Jonathan Shepherd, Frank Sikora, Desiree Szarka, Raul Villanueva | Mar. 13, 2020 (New)
Hemp is grown for fiber, grain, and cannabinoid extraction in Asia, Europe, and the Americas. Until recently, Cannabis sativa has been classified as a Schedule 1 controlled substance in the US. The Agricultural Act of 2014 (Farm Bill) allowed for reintroduction of industrial hemp under a pilot research program. Acreage increases and addition of state legislation resulted in over 78,000 acres of hemp grown in 23 states by the end of 2018. Hemp became a legal commodity under the 2018 Farm Bill, and by the end of 2019, over 500,000 licensed acres were documented across 45 states. Canada re-introduced the crop in 1998, and in 2018, almost 78,000 acres of hemp were licensed and planted.
