PPFS-FR-T-8: Bacterial Canker and Perennial Canker of Stone Fruit
Nicole Ward Gauthier, Kevin Lyons, Chris Smigell | Sep. 9, 2021 (Major Revision)
Gummosis is a general, nonspecific condition of stone fruits (peach, nectarine, plum and cherry) in which gum is exuded and deposited on the bark of trees. Gum is produced in response to any type of wound, regardless of whether it is due to insects, mechanical injury or disease.
PPFS-FR-T-16: Sooty Blotch and Flyspeck of Apple
Nicole Ward Gauthier | Jan. 26, 2021 (New)
Sooty blotch and flyspeck (SBFS) is a common late summer disease complex. The resulting superficial blemishes do not cause fruit decay, but they can reduce market value for commercial produce. Infections of the waxy cuticle can also shorten storage life, as it allows for accelerated desiccation during refrigerated storage.
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.
PPFS-FR-T-9: Peach Fruit Diseases
Nicole Ward Gauthier | Mar. 9, 2020 (Major Revision)
Peach fruit diseases can cause significant losses in yield and quality in commercial and home orchards. Often these diseases go unnoticed until late in the season or at harvest. Although there are no curative treatments for infected fruit, many diseases can be prevented using cultural practices and (optional) fungicides. Accurate diagnosis, however, is critical to determine the best management practices and to prevent future losses.
PPFS-FR-T-26: Cultural Calendar for Commercial Peach Production
Ric Bessin, Kimberly Leonberger, Matthew Springer, John Strang, Nicole Ward Gauthier, Shawn Wright | Aug. 1, 2019 (New)
Integrated 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. Extension offices can also provide updated pest management recommendations. This cultural guide serves as a supplement to published spray guides and scouting guides.
PPFS-FR-T-2: Apple Fruit Diseases Appearing at Harvest
Nicole Ward Gauthier | Aug. 1, 2019 (Minor Revision)
Diseases of apple fruits appearing at harvest can cause significant losses in yield and quality. To know what control measures to take next year to prevent similar losses, it is important to recognize what is being observed. In some cases, growers will need to cut the fruit open to identify the problem.
PPFS-FR-T-24: Bitter Rot of Apple
Kimberly Leonberger, Madison McCulloch, Nicole Ward Gauthier | Aug. 1, 2019 (New)
Bitter rot is the most common fruit rot of apple in Kentucky. Trees in both commercial and residential plantings can suffer devastating losses. Growers consider bitter rot the most important fruit rot and the second most destructive disease in Kentucky apple orchards. Yield losses can range from 10% to 100%.
PPFS-FR-T-25: Cultural Calendar for Commercial Apple Production
Ric Bessin, Kimberly Leonberger, Matthew Springer, John Strang, Nicole Ward Gauthier, Shawn Wright | Aug. 1, 2019 (New)

PPFS-FR-T-20: Simplified Backyard Peach and Stone Fruit Spray Guide
Ric Bessin, John Strang, Nicole Ward Gauthier | Jul. 1, 2019 (Minor Revision)
Peach, nectarine, apricot, plum, and cherry are all stone fruits. Production of these tree fruits requires pest and disease management programs for quality fruit. Home orchards are no different. Homeowners, however, are generally more tolerant of aesthetic maladies or minor crop losses than commercial orchardists. Thus, homeowners may choose to limit numbers of insecticide and fungicide sprays. Disease resistant cultivars are the preferred method for reducing spray inputs.
PPFS-FR-T-23: Commercial Peach/Stone Fruit Fungicide Spray Schedule Worksheet
Nicole Ward Gauthier | Jul. 1, 2019 (Minor Revision)
A spray schedule worksheet for commercial peach/stone fruit growers.
