My goal is to learn when we can apply disease management practices to achieve the best disease control. The research I do as part of the PVY Management program focuses on PVY epidemics, the rate symptoms develop in individual plants, disease spreads to others, and the resulting yield loss.
Current research projects include:
> Long-term storability of PVY-infected tubers
In the first year of preliminary research, we have documented significant reductions in storage quality parameters including percent solids and shrinkage. This area of investigation seems extremely important towards limiting continued storage losses and further assessing the impact of plant disease (PVY infection) on seed tuber physiological age. (Research proceedings).
> Aphid flight dynamics and occurrence of PVY infection
The goal of this project has been to document the seasonal phenology of aphid vector species and their relationship to PVY incidence in the field. Replicated field plots were set up in Wisconsin using green tile pan traps and sentinel potato plants. Sentinel plants were left in the field for a week, then held in an aphid-proof greenhouse for PVY disease development and detection. Over a similar sample interval, aphids were collected from green tile pan traps and identified to species . Correlating aphid movement with PVY disease progress will help to define the relative importance of specific aphid vectors in driving recent PVY disease cycles.
