Rice Pesticide Program

Rice Pesticide Program

Program Overview

The Rice Pesticide Program is a longstanding watershed effort whereby rice growers follow Board-approved management practices contained in use permits obtained from Agricultural Commissioners when applying selected rice pesticides. The Program includes monitoring of Sacramento Valley agricultural drains and the Sacramento River by the California Rice Commission (CRC). The Cities of Sacramento and West Sacramento also conduct monitoring at their drinking water intakes on the Sacramento River. Monitoring is conducted during the peak discharge period for ten weeks from late-April through June to capture the thiobencarb use season. The current Rice Pesticide Program resolution (R5-2010-9001) was adopted in 2010 and outlines the program requirements.
