Chlorpyrifos Mitigation Documents and Activities

Back to Mitigating Exposure

Chlorpyrifos Mitigation

These documents describe the controls that DPR has developed to reduce risk from exposure that might occur near fields treated with products containing chlorpyrifos when labeled for the production of agricultural commodities.

Chlorpyrifos Regulations

In response to exposure concerns associated with off-site movement, the Department of Pesticide Regulation (DPR) proposed to designate chlorpyrifos as a restricted material when labeled for the production of agricultural commodities. This designation will facilitate county agricultural commissioner (CAC) oversight of chlorpyrifos use by applicators. CACs will be able to evaluate chlorpyrifos use in the specific local conditions of each application and consider permit conditions to further protect bystanders and the environment.

Related Chlorpyrifos Regulations

To meet federal ozone air quality standards, DPR is required to reduce volatile organic compounds (VOC) emissions from pesticides. To that end, DPR adopted regulations to reduce VOC emissions from nonfumigant pesticides. The regulations set a trigger level of emissions that, if exceeded, invokes limitations to high-VOC products containing chlorpyrifos (among other products) when used from May 1 to October 31 on alfalfa, almonds, citrus, cotton, grapes, pistachios, and walnuts grown in the San Joaquin Valley.
