SACRAMENTO – The Environmental Working Group today applauded the California Department of Pesticide Regulation’s announcement that all manufacturers of pesticide products containing paraquat-dichloride have voluntarily cancelled their registrations that allow them to sell paraquat in the state.
The decision starts the phase-out of one of the most toxic weedkillers in use in California agriculture. It’s a major step toward protecting farmworkers, agricultural communities and the environment from a highly toxic herbicide linked to Parkinson’s disease, thyroid disease, childhood leukemia, non-Hodgkin lymphoma and birth defects.
“California is sending a powerful message that there is no place for paraquat in modern agriculture,” said Bernadette Del Chiaro, EWG’s senior vice president for California. “The fact is, farmworkers and nearby communities have been unprotected from the health threats of paraquat making this decision long overdue.
“That, along with the tragic spill in Dorris put the writing on the wall that paraquat’s days were numbered,” said Del Chiaro.
In March, a large container of paraquat fell from a truck in the northern California town Dorris, spilling roughly 60 gallons of the chemical onto a major roadway and into the surrounding community. Citing the risk of exposure to airborne paraquat releases, officials ordered a lockdown affecting about 600 residents, including those at a local elementary school.
