This regulation establishes an exemption from the requirement of a tolerance for residues of Bacillus pumilus strain BU F-33 in or on all food commodities when applied to elicit induced systemic resistance in plants and used in accordance with label directions and good agricultural practices. Becker Underwood, Inc., submitted a petition to the EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA) requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of Bacillus pumilus strain BU F-33 under the FFDCA.
