This regulation establishes an exemption from the requirement of a tolerance for residues of the microbial pesticide, Aspergillus flavus AF36, in or on corn food and feed commodities, when applied/used as an antifungal agent. The Arizona Cotton Research and Protection Council submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting an amendment to the existing exemption from the requirement of a tolerance for Aspergillus flavus AF36. This regulation eliminates the need to establish a maximum permissible level for residues of Aspergillus flavus AF36 under the FFDCA.
