Welcome to the Department of Pesticide Regulation

U.S. – Mexico Border Project

Back to Pesticide Use Enforcement


The Department of Pesticide Regulation (DPR) works with several state and federal agencies, along with authorities from Mexico, to foster effective enforcement of pesticide laws in the border area, a zone extending 100 miles north and south of the U.S./Mexico border.

Pesticide Episode Response Plan

The Pesticide Episode Response Plan began in 1995 after pesticide drift incidents in the Calexico/Mexicali area. It provides a framework for local, state, and federal agencies in both California and Mexico to communicate and coordinate responses to pesticide emergencies.

Residue Tracking Program

California and Baja California promotes efforts to reduce illegal pesticide residues on produce. The primary goals of the program are to establish a database and improve tracking procedures on shipments of produce from Mexico found to contain illegal residues. Staff work with representatives of the Secretaria de Agricultura, Ganaderia, Desarrollo Rural, Pesca y Alimentacion when commodities for sale in California are found contaminated with illegal pesticide residues. DPR staff provides training to border region agricultural officials and the grower community on strategies that reduce drift and pesticide contamination of produce.

U.S./Mexico Pesticide Information Exchange Program

The main goal of this program is to exchange information at the state and federal level between the governments of the United States, Mexico, and the Border States. Information includes the regulation of pesticides; exchange personal and professional contact information; facilitate the discussion and resolution of pesticide issues along the border; and provide training and instruction on specific areas of pesticide regulation.
