Kentucky lawmakers have enacted a new law aimed at protecting pesticide manufacturers from a growing wave of lawsuits, overriding a veto from Democratic Gov. Andy Beshear and reinforcing a broader push to align state rules with federal science-based standards.
The Republican-led legislature last week approved Senate Bill 199 over Beshear’s objections, establishing that pesticide labels approved by the Environmental Protection Agency meet state warning requirements. Supporters say the change provides much-needed certainty for farmers and crop protection companies facing costly litigation tied to products that have already undergone federal safety reviews.
Agricultural groups, including the Kentucky Farm Bureau, argued the measure helps prevent rising legal costs from being passed down to producers at a time when margins are already tight. Industry advocates point to thousands of lawsuits filed in recent years—many centered on glyphosate, a widely used herbicide—despite the EPA’s determination that it is not carcinogenic and does not require a cancer warning label.
Backers of the law say allowing state-level lawsuits to impose additional warning requirements creates a patchwork system that conflicts with federal oversight under the Federal Insecticide, Fungicide, and Rodenticide Act. They contend that without clearer legal protections, manufacturers could be forced to add warnings not supported by federal science or withdraw products from the market altogether, limiting tools farmers rely on to control weeds and protect yields.
The Kentucky law applies specifically to failure-to-warn claims and preserves liability in cases where a company is found to have misled regulators. Still, supporters say it strikes the right balance by upholding federal authority while maintaining accountability for misconduct.
Kentucky’s action reflects a growing national trend, with several states considering similar legislation and Congress weighing provisions that would further standardize pesticide labeling requirements. The U.S. Supreme Court is also expected to weigh in on the issue, a decision that could ultimately determine how much authority states have to regulate pesticide warnings beyond federal guidelines.
