The Department of Pesticide Regulation is scheduling a hearing to determine if it should allow the registration of imidacloprid to continue for agricultural use.

Last year DPR discovered 15 groundwater wells in Fresno, Santa Barbara and Tulare counties tainted with high concentrations of the neonicotinoid. DPR determined the contaminants came from legal use of the pesticide.

At the hearing, DPR’s advisory committee for pesticide registration will review the evidence and take testimony from registrants, along with other public comments, before providing recommendations to the DPR director.

The first part of the hearing will take place March 22–24; the second part is still to be determined.
