Monsanto v. Durnell · ¶98

FIFRA fits this mold. It is a federal statute that regulates the sale and use of pesticides, and among other things, requires that pesticides bear detailed labels providing consumers with information about how to use them and what risks they pose. FIFRA expressly limits States’ authority to regulate pesticide labels, but it does not eliminate that authority. Instead, FIFRA preempts only those state “requirements for labeling or packaging in addition to or different from” the requirements under FIFRA. §136v(b). This means that state labeling requirements “equivalent to” FIFRA’s requirements are not preempted. Bates, 544 U. S., at 447. In other words, FIFRA’s preemption clause does not block state-law claims where the violation of state law is also a violation of FIFRA. Id., at 454.
