Montana Attorney General Austin Knudsen joined a 15-state coalition in asking the Supreme Court to uphold uniform national labeling requirements for farming herbicides. The goal is to ensure farmers have access to glyphosate, a proven safe and environmentally friendly weed control tool in agriculture. The brief was filed in “Monsanto v. John Durnell.” “Permitting states to impose labeling requirements on glyphosate products will have disastrous consequences for farmers and agriculture industries,” the attorneys general wrote in the brief. “Prices will increase, discouraging use of the best and safest product and causing deteriorating downstream effects on consumers and the environment.” Without a nationwide standard, states such as California could impose individual labeling requirements that disrupt supply chains nationwide, leading to increased costs for farmers around the country and threatening their access to glyphosate. Less access could force farmers to use other, often more toxic herbicides in place of glyphosate.
