DPR 22-001 – Neonicotinoid Pesticide Exposure Protection

DPR 22-001 Neonicotinoid Pesticide Exposure Protection (Noticed 2/25/22; Comment period closed 4/26/22; “15-day” comment period 10/5/22-10/21/22)

DPR adopted sections 6990 through 6990.16 of Title 3, California Code of Regulations as control measures necessary to protect pollinator health as identified in the “California Neonicotinoid Risk Determination” and “Addendum to the July 2018 California Neonicotinoid Risk Determination.” The control measures would affect the pesticide regulatory program activities pertaining to pesticide use and enforcement by regulating certain production agricultural applications of pesticide products containing the nitroguanidine-substituted neonicotinoid active ingredients, clothianidin, dinotefuran, imidacloprid, and thiamethoxam (collectively referred to as neonicotinoids). In summary, the control measures consist of application method and rate restrictions, application timing restrictions, and seasonal application rate caps for the four-neonicotinoid active ingredients and are specific based on crop group.

A virtual public hearing was held on April 25, 2022, to receive oral or written comments regarding the proposed changes.
