Objective:
The overall objective of this proposal is to refine the current management strategies based on industry needs to reduce overall levels of PVY and prevent the continued spread of necrotic and recombinant strains.

Approach:
Our overall objective in this proposal is to refine the current management strategies used by the certification agencies to reduce the initial virus inoculum planted in the field and those used by growers to reduce the spread of virus within the crop. Specifically, we will 1. Work with seed certification agencies to monitor PVY strains and develop new diagnostic and training tools to better identify and eliminate PVY from seed stocks. "Specialty Crops Research Initiative" 2. Work with breeding programs to better recognize and screen for virus resistance and symptom expression. 3. Work with growers to develop cost effective virus control strategies for both minituber and conventional seed production that can be implemented on the farm.
