NOTICE TO PESTICIDE REGISTRANTS
REGARDING INITIATION OF RISK ASSESSMENT PROCESS
FOR THE ACTIVE INGREDIENT
SULFURYL FLUORIDE
This notice informs registrants that the Department of Pesticide Regulation (DPR) is initiating the risk assessment
process for registered pesticide products containing the active ingredient sulfuryl fluoride.
Food and Agricultural Code (FAC) sections 13121-13130 require DPR to review the toxicology database of all registered
pesticide active ingredients. In addition, FAC section 12824 requires DPR to endeavor to eliminate from use in
California any pesticide that endangers the agricultural or nonagricultural environment. DPR identified sulfuryl
fluoride as having potential adverse health effects in studies of sufficient quality to allow risk characterization.
During the risk assessment process, DPR evaluates the significance of the adverse effects. If DPR decides that
use of, or certain uses of, the active ingredient sulfuryl fluoride result in a significant adverse effect, action
must be taken to mitigate the adverse effect.
When DPR identifies the endpoints of toxicological significance, you will be informed of those endpoints and given
an opportunity to provide comments.
Please address all requests for additional information to, Ms. Ann Prichard by e-mail at aprichard@cdpr.ca.gov
or by telephone at (916) 324-3931.
