This regulation establishes an exemption from the requirement of a tolerance for residues of the biochemical pesticide Reynoutria sachalinensis extract on all food commodities. The Interregional Research Project Number 4 (IR-4), on behalf of KHH Bioscience, Inc., submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), as amended by the Food Quality Protection Act of 1996 (FQPA), requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of Reynoutria sachalinensis extract.
