The EPA has 60 days to either write a new rule to allow for the safe use of chlorpyrifos or halt all food residue tolerances of the insecticide, which would effectively ban most uses of it, according to a ruling handed down by a federal court on Thursday.
In an opinion from the U.S. Court of Appeals for the Ninth Circuit in San Francisco, the court said EPA has had long enough to respond to a 2007 petition by environmental groups to ban the chemical.
