outreach overview
- The biocontrol research is expected to result in improved products for nontoxic control systems for control of plant diseases and to improve plant productivity and yield. I am focused on commercial vehicles for delivery of these. Similarly, I am engaged in a local start-up company, Terrenew, that is well along towards commercial utilization of agricultural waste products, through appropriate processing and manufacturing systems, for pollution remediation and that is located in the Cornell Agricultural and Food Technology Park.
