He has been working with Hudson Valley agricultural producers for over 30 years.

Peter now works as a research entomologist and educational outreach coordinator under Poma Tech Inc.,  a 501(c)(3).  He continues to conduct research for the agricultural industry, presently focusing on yearly insecticide efficacy screening studies of new and alternative tools for insect control on regional orchards. Trial results will continue to provide growers with decision making information for use in commercial fruit production.

Further studies with Poma Tech Inc. include invasive insect monitoring, mapping and management, development of sustainable Ag. production systems employing biological control, mating disruption and attract and kill systems.

Weekly 6AM Monday ‘Morning Brew’ from April to September will focus on weekly upcoming pest management decision making. 


We strive to work directly with regional agriculturalists to solve insect pest related issues, employing effective, economically viable, integrated approaches for IPM production systems.
