This regulation establishes an exemption from the requirement of a tolerance for residues of isoamyl acetate (CAS Reg. No. 123-92-2) when used as an inert ingredient (buffering agent) in pesticide formulations applied to growing crops and raw agricultural commodities after harvest. The Technology Sciences Group on behalf of the Jeneil Biosurfactant Company submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting establishment of an exemption from the requirement of a tolerance.
