This regulation establishes an exemption from the requirement of a tolerance for residues of Pasteuria spp. (Rotylenchulus reniformis nematode)--Pr3 in or on all food commodities when applied as a nematicide and used in accordance with label directions and good agricultural practices. Pasteuria Bioscience, Inc. 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 spp. (Rotylenchulus reniformis nematode)--Pr3 under the FFDCA.
