What does it really mean when we talk about the “impact” of pesticides? In this episode, we explore the origin and purpose of the Environmental Impact Quotient (EIQ)—a tool designed to translate pesticide use into measurable environmental impact.

Frank Rossi reflects on his early work with the EIQ, stemming from the apple industry and later extending into turfgrass, where it became a way to demonstrate the thoughtful, environmentally aware decisions turf managers make every day. He also revisits his original collaboration with Jennifer Grant, former New York State IPM director, and Bob Portmess, former extension associate, who helped shape the EIQ into a tool in pest management.
