Overall summary: refining the AYI Advance our basic understanding of the epidemiology of aster yellows in Wisconsin towards the development and implementation of a comprehensive management plan Incorporate biological information about the AY disease system from multiple scales to improve on-farm AY management decisions Utilize available and emerging technologies in the context of management to: I) Ensure AYp detection is accurate and reflects biology – Reduce unwarranted sprays II) Identify trends in AY risk – Target control to high AY risk periods, offset high costs of new “softer” chemistries
