Info

Research update Part I) Identify trends in AY risk - Use historical data collections - Target control to high AY risk periods, offset high costs of new “softer” chemistries Part II) Advance predictive tools to address sporadic risks - Integrate previous research findings into current management - Allow advanced preparation for ALH infestations to mitigate yield loss
Part I: Research questions AYI = relative leafhopper abundance * % infectivity Can we better understand the factors that are important for the variability in insect abundance and infectivity in carrot fields Can we discover and exploit temporal trends in either of the components of the AYI
