The main purpose of this legislation is to amend the Federal Insecticide, Fungicide, and Rodenticide Act to ensure that state laws regarding pesticide misbranding are not overridden by federal law. This aims to enhance consumer protection by allowing state-level claims related to pesticide labeling and safety to be pursued, even if they align with federal standards. Key provisions of the legislation include the clarification that state law claims concerning pesticide misbranding are preserved and not preempted by federal law.
