LOS ANGELES—A widely used agricultural pesticide that California environmental officials have said has been linked to brain damage in children will be banned after next year under an agreement reached with the manufacturer, state officials announced Wednesday, Oct. 9.
Under the deal, all California sales of chlorpyrifos will end on Feb. 6, 2020, and farmers will have until the end of 2020 to exhaust their supplies.
The pesticide is used on numerous crops in the nations largest agriculture-producing state—including alfalfa, almonds, citrus, cotton, grapes, and walnuts.

State regulators have said chlorpyrifos has been linked to health defects in children, including brain impairment, and to illnesses in others with compromised immune systems.
“This is a big win for children, workers and public health in California,” Gov. Gavin Newsom, a Democrat, said in a statement after the deal was announced.
The president of the California Citrus Association, which represents about 5,000 growers, said in an interview that he believes the risks were not as great as the state made them out to be.
“We really thought the exposure assessments and risks were just inflated and it wasnt a true characterization of the protections that were already in place,” said Casey Creamer.
Creamer added he appreciated that officials have agreed to budget $5.6 million to help pesticide manufacturers develop a safer alternative to chlorpyrifos.
“But just so youre aware, thats what agriculture does every day, were always looking for new products, safer products that are effective,” he said.
