This regulation establishes an exemption from the requirement of a tolerance for residues of diisopropyl adipate when used as an inert ingredient (solvent) in pesticide formulations applied to pre- and post-harvest crops under EPA regulations at no more than 40% in formulated products intended for mosquito control. Wellmark International submitted a petition prepared by Technology Sciences Group Inc. to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting establishment of an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of diisopropyl adipate.
