Cotton growers in Pima County, Arizona are working together to implement a community-wide Integrated Pest Management program. Participation is voluntary; and is unanimous in at least some components of the program. The IPM program employs many control components aimed at the pink bollworm, the principle cotton insect pest in the area. Growers time the deployment of the control components to act in unison throughout the community. Insecticide applications in the area have trended downward since the program began in 1991, indicating that we are making progress toward our goal of reducing the reliance on pesticides.
