As the cost of litigation soared, Bayer ramped up its support to alter pesticide labeling in states across the country. Legislation in Missouri and across states from Montana to Florida has looked to address pesticide labeling and product liability. The bills stated that if a pesticide product is approved by the U.S. Environmental Protection Agency, or is consistent with the agency’s cancer classifications, it doesn’t need additional cancer warning labels. Bills have failed in several other states, including Missouri, where two identical pesticide bills backed by Bayer died when the session ended in May. While no Missouri pesticide labeling bills became law in the 2025 session, an identical bill, House Bill 544, did pass the House.
