The Department of Pesticide Regulation (DPR) adopted regulations to reduce potential runoff and surface water contamination from nonagricultural applications of specified pyrethroid pesticide products, effective July 19, 2012.

Implementation Information

To help County Agricultural Commissioners train their staff or stakeholders about the new regulations, DPR posted a PowerPoint presentation on the DPR external web site under the Enforcement Training web page. The PowerPoint includes examples of acceptable and prohibited application methods

The new regulation limits many applications to crack and crevice, spot or pin stream applications. Crack and crevice applications and spot treatments are defined in 3CCR section 6000. DPR characterizes a pin stream application as an application of a narrow band to a surface where no crack or crevice is present, such as an application that deposits a one inch band onto the surface around windows or doors.
