This regulation establishes an exemption from the requirement of a tolerance for residues of Trichoderma atroviride strain K5 NRRL B- 50520 in or on all food commodities when used in accordance with label directions and good agricultural practices. Agrauxine Corp., submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting the exemption from a requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of Trichoderma atroviride strain K5 NRRL B-50520 under FFDCA when used in accordance with the terms of the exemption.
