The overall goal of our research is to develop integrated pest management systems for small fruit crops, nursery crops, and hops. Our objective is to reduce synthetic chemical inputs through augmentation or replacement with biologically based control strategies.

 

Pathogen epidemiology and the microbial ecology of plant surfaces are being investigated to understand how to better implement biological control strategies for control of plant pathogens.

 

Our research on small fruit crops focuses on powdery mildew (Uncinula necator) and gray mold fruit rot (Botrytis cinerea).

 

The nursery crops component of our program includes the discovery and development of biological control agents against Botrytis spp. and the use of compost for disease control.
