Which act requires all pesticides to be labeled according to specific guidelines?

The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) is the correct answer because it establishes the legal framework for the registration, distribution, sale, and use of pesticides in the United States. One of its key requirements is that all pesticides sold or distributed in the U.S. must be labeled according to specific guidelines set forth by the Environmental Protection Agency (EPA). This includes providing essential information on safe use, handling, and environmental protection measures.

FIFRA's labeling requirements are designed to ensure that users are adequately informed about how to safely apply pesticides, the potential risks to human health and the environment, and the necessary precautions to take. This ensures that both the applicators and the general public are protected from misuse or accidental exposure.

Other acts mentioned may have their own regulations relating to pesticides or broader environmental concerns, but none specifically address pesticide labeling with the same comprehensive approach as FIFRA.
