Objectives and Anticipated Impacts: The overall objective of this project is to develop advanced, biointensive apple IPM tactics and apply them in a system to reduce pesticide reliance and lower non-target pesticide impacts. Specific objectives address seven key areas. 1. Plum curculio - use a trap tree approach to replace general orchard sprays. 2. Apple maggot - use pesticide-treated sphere traps for management rather than general orchard sprays. 3. Obliquebanded leafrollers and internal Lepidoptera - use seasonal fruit monitoring programs for optimizing insecticide treatments. 4. Eliminate organophosphates and use pesticides with fewer non-target impacts. 5. Apple scab - use potential ascospore dose, inoculum destruction and degree-day model to delay initial fungicide applications in the following season and end applications when unnecessary. 6. Sooty blotch and flyspeck - develop model-directed applications of reduced-risk fungicides. 7. Eliminate carbaryl - for fruit thinning, develop approaches that do not use carbaryl as a thinning agent.
Use a trap tree approach to replace general orchard sprays in plum curculio. Use pesticide-treated sphere traps for management rather than general orchard sprays for apple maggot.
