Pesticide warning labels.

HB 285 requires pesticide manufacturers and sellers in Wyoming to use warning labels approved by the U.S. Environmental Protection Agency (EPA) under federal law to meet their legal duty to warn consumers about risks. This creates a legal presumption that warnings are sufficient if based on EPA-approved labels and federal registration, shifting the burden to challenge this if scientific evidence shows the warning wasn't supported by peer-reviewed research. To rebut the presumption, challengers must provide academically peer-reviewed, published evidence demonstrating the warning lacked scientific support at the time of sale. The bill takes effect July 1, 2025, directly affecting pesticide manufacturers, sellers, and consumers relying on label warnings.
