This regulation establishes tolerances for residues of acibenzolar-S-methyl in or on onion, bulb, subgroup 3-07A; and vegetable, cucurbit, group 9. It also removes the section 18 time- limited tolerance on onion, bulb which is superseded by the new tolerance on onion, bulb, subgroup 3-07A. Interregional Research Project Number 4 (IR-4) and Syngenta Crop Protection requested these tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA).
