California Farm Bureau Files Amicus in U.S. Supreme Court Case on Pesticide Labeling and Roundup
Published Friday, June 26, 2026
On June 25, the U.S. Supreme Court issued its opinion in Monsanto Co. v. John L. Durnell. California Farm Bureau, along with 12 other state Farm Bureaus, submitted an amicus brief to the U.S. Supreme Court in March, urging the court that the Federal Insecticide, Fungicide, and Rodenticide Act, or FIFRA, prevents states from imposing additional or different labeling requirements on pesticides. In its decision, the nation’s highest court agreed with our position and disagreed with the decision by the Missouri Court of Appeals. The U.S. Supreme Court’s opinion affirms that federal law regulating the sale and labeling of pesticide products bars failure-to-warn lawsuits in state courts.
