This regulation establishes an exemption from the requirement of a tolerance for residues of the microbial pesticide, Pasteuria usgae, in or on all food commodities when applied preharvest and used as a nematicide in accordance with good agricultural practices. MacIntosh and Associates Incorporated (on behalf of Pasteuria Bioscience Incorporated) submitted a petition to 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 Pasteuria usgae.
