This regulation revokes the tolerance exemption for residues of the antimicrobial pesticide ingredient phenol when used as an inert ingredient (solvent/cosolvent) in pesticide formulations applied to growing crops. This rulemaking is established on the Agency's own initiative under the Federal Food, Drug, and Cosmetic Act (FFDCA) to implement a tolerance action the Agency determined was appropriate during the registration review conducted under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) for phenol.
