Supreme Court Rules FIFRA Preempts State Failure-to-Warn Claims: Monsanto v. Durnell Explained - Crowell & Moring LLP
The Supreme Court ruled that FIFRA preempts state failure-to-warn claims, meaning pesticide applicators cannot be sued under state law for inadequate labeling if the label complies with FIFRA. This reduces litigation risk for applicators using EPA-approved labels.
Aforeworn detected this change in the Pesticide & Pest-Control Applicators space on July 6, 2026 and published this briefing so affected operators are forewarned rather than caught off guard.
