My research is focused on developing sustainable production methods for berry crops. A major focus is on environmental modifications, primarily using high and low tunnels, to produce tender crops (e.g. blackberries) in colder climates, and to extend the season into fall for strawberries and raspberries. Managing weeds is a major challenge for berry growers and using non-herbicidal approaches (such as integrating cover crops and reduce tillage planting systems) is a significant component of my research program. Also, using cultural practices to reduce damage from pests (e.g. black root rot, Phytophthora root rot, tarnished plant bug) is another facet of my research. Finally, I am interested in better understanding some of the basic physiological responses of berry crops to the environment and developing ways to improve plant growth and productivity.
Outreach and Extension Focus
I believe that we have a responsibility to help educate all citizens (not just commercial growers) about issues that affect their lives. In my case, this education involves issues of food choice, sustainability, food safety and food quality. One of my professional objectives is to be a credible resource on these broader issues, in addition to developing a high level of expertise in berry crops. The audience for my extension program is national. Many of my presentations are given to out-of-state audiences, many phone calls come from out-of-state, and the printed materials and electronic resources are written for a regional audience. Berry crops are the most widely grown of all fruit crops, so the audience is dispersed throughout the entire northeastern United States and Canada. In addition to commercial berry crops, I have worked on developing Good Agricultural Practices materials to improve food safety on the farm. I also attempt to allocate a portion of my outreach efforts to non-commercial audiences, both youth and adult. Occasionally I present and consult internationally. I strive to inform all audiences about the many issues that affect the food system.
