This regulation establishes an exemption from the requirement of a tolerance for residues of laminarin in or on all food commodities when applied preharvest as a biochemical pesticide to stimulate natural defense mechanisms in plants. Laboratoires Go[euml]mar SA c/o SciReg, 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 laminarin.
