the EPA under the authority of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)
through the product labeling, and all necessary and appropriate precautionary, use, storage, and
disposal information is set forth on that labeling. It is a violation of federal law to use a pesticide
product in any manner not prescribed on the EPA-approved label.
