Monsanto v. Durnell · ¶83

With respect to pesticide labels, FIFRA demands “[u]niformity” and expressly preempts state labeling requirements that are “in addition to” or “different from” federal labeling requirements. §136v(b). Durnell’s state- law failure-to-warn claim would require a cancer warning on Roundup’s label—a requirement “in addition to” and “different from” the label required by EPA under FIFRA. FIFRA therefore expressly preempts Durnell’s claim. We reverse the judgment of the Missouri Court of Appeals and remand the case for further proceedings not inconsistent with this opinion.
