Presentation Outline Goal - Sustainable Carrot IPM ‣ Define Aster Yellows disease and the insect vector ‣ Identify periods of ‘elevated risk’ for disease transmission. ‣ New approaches to achieve sustainable, reduced-risk, IPM in carrot. Seed Treatments
Next Steps - 2011: Using information about periods of elevated AY risk What tactics or combinations of tactics, can effectively provide plant protection during high AY risk period (i.e. planting later, insecticide treated seed, and/or fewer applications of reduced risk insecticides) •- Compare reduced risk and less broad spectrum insecticides (neonicotinoid) to current AY management (seed treatments and foliar applications) •- Timing of foliar applications based on ALH infectivity, AY risk phenology and degree day model forecasting the emergence of local ALH
