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 created printable maps covering the entire County of Colusa (ledger-size with the ability to print as ledger and letter-sizes). We have also included poster size maps with a higher resolution. Please contact our office if you have any questions regarding these maps.
