The U.S. Supreme Court ruled 7-2 on June 25 that plaintiffs cannot sue Bayer for failing to include cancer warning labels on glyphosate products, citing federal preemption over state laws. Following the ruling, Bayer petitioned a federal judge to dismiss approximately 4,000 consolidated lawsuits. The company stated the decision provides regulatory clarity necessary for innovation, while the Environmental Working Group criticized the administration's stance as favoring large corporations over public health.
In February 2026, the Environmental Protection Agency (EPA) approved the use of the weedkiller dicamba for the next two growing seasons. The approval includes new restrictions, such as lower application rates and temperature-based limits, intended to prevent the chemical from drifting onto neighboring crops. The Center for Biological Diversity has challenged the move, arguing that the new guardrails are insufficient to prevent environmental damage.
Additionally, the U.S. Fish and Wildlife Service issued a biological opinion in April concluding that the herbicide atrazine does not pose an extinction risk to studied endangered species. This finding is part of an ongoing EPA registration review. While the Centers for Disease Control and Prevention notes that some studies have suggested potential links between atrazine and specific health risks, the Fish and Wildlife Service stated the chemical's continued registration is unlikely to jeopardize the existence of the species under review.
