Pesticide Buffer Zone Maps

Certain crops, such as walnuts, peaches, nectarines, and prunes, are highly sensitive to specific pesticides that are commonly used in agricultural practices. Colusa County Agricultural Biologists have created annual maps to promote quality control of these crops during pesticide applications.

For your convenience, we have linked an updated 2025 interactive map tool to determine where sensitive crops are located in Colusa County and the buffer zones they require. Follow the link below to learn more.
