PPFS-AG-T-5: Maintaining the Efficacy of Foliar Fungicides for Tobacco Disease Management
Bob Pearce, Emily Pfeufer | Jul. 1, 2019 (Minor Revision)
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.
PPFS-FR-T-18: Simplified Backyard Apple Spray Guides
Ric Bessin, John Strang, Nicole Gauthier, Beth Wilson | Jul. 1, 2019 (Minor Revision)
Apple production 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.
PPFS-FR-T-21: Backyard Apple and Pear Disease, Pest, and Cultural Practices Calendar
Ric Bessin, Kimberly Leonberger, John Strang, Nicole Gauthier, Shawn Wright | Jul. 1, 2019 (Reviewed)
Backyard apple production requires a proactive approach to disease, insect, and weed management. Preventative practices are recommended to minimize inputs. While intensive culture may result in the highest quality fruit, reduced inputs can result in acceptable fruit with minor crop losses or aesthetic maladies. This guide focuses on preventative cultural practices with options of low-input pesticide applications. Refer to the homeowner fruit spray guide (ID-21) for a more complete pesticide spray schedule.
PPFS-FR-S-18: Effectiveness of Fungicides for Management of Grape Diseases
Nicole Gauthier | Jul. 1, 2019 (Minor Revision)
This guide is a decision-making tool to help growers select fungicides from different chemical classes (FRAC). Additional information can be found in a number of UK Cooperative Extension Service publications, including ID-232, or by contacting county Extension agents.
PPFS-FR-S-21: Sample Fungicide Spray Schedule for Commercial Blueberry
Nicole Gauthier | Jul. 1, 2019 (Minor Revision)
A sample fungicide spray schedule for commercial blueberry growers (table).
PPFS-OR-T-2: Reducing the Risk of Resistance to Fungicides Used to Control Diseases of Turfgrasses
Paul Vincelli | Jul. 1, 2019 (Minor Revision)
Fungicides can be an important tactic in an overall integrated program for turf disease control. In order to insure that products available today remain available in the future, golf course superintendents should be aware of the need to use fungicides in ways that minimize the risk of fungicide resistance.
PPFS-VG-1: Black Rot of Crucifers
David Davis, Emily Pfeufer | Jul. 1, 2019 (Minor Revision)
Black rot, caused by the bacterial pathogen Xanthomonas campestris pv. campestris (Xcc), can be a very destructive disease of cabbage, cauliflower, and broccoli. Other susceptible crucifers include: collards, kale, Brussels sprouts, Chinese cabbage, kohlrabi, turnip, mustard, radish, and rutabaga.
