This regulation establishes an exemption from the requirement of a tolerance for residues of glycine betaine (CAS Reg. No. 107-43-7) when used as an inert ingredient (plant nutrient) in pesticide formulations applied to growing crops only. SciReg, Inc., on behalf of Fine Agrochemicals Ltd, submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting establishment of an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of glycine betaine.
