This regulation amends the existing exemption from the requirement of a tolerance for residues of polyoxin D zinc salt when used as a fungicide on almonds, cucurbit vegetables, fruiting vegetables, ginseng, grapes, pistachios, pome fruits, potatoes, and strawberries by expanding the current exemption to include all food commodities. This regulation establishes an exemption from the requirement of a tolerance for residues of polyoxin D zinc salt in or on all food commodities when applied as a fungicide and used in accordance with good agricultural practices. On behalf of Kaken Pharmaceutical Co., Ltd., Conn & Smith, Inc. submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting that EPA amend the existing exemption from the requirement of a tolerance for polyoxin D zinc salt. This regulation eliminates the need to establish a maximum permissible level for residues of polyoxin D zinc salt under the FFDCA.
