This regulation establishes tolerances for residues of flumioxazin in or on vegetable, cucurbit, group 9; leaf petioles subgroup 4B; and hop, dried cones. This regulation additionally deletes the existing tolerances on almond and melon, subgroup 9A, as they will be superseded by inclusion in tree nut group 14 and cucurbit vegetable group 9, respectively. Interregional Research Project Number 4 (IR-4) requested these tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA).
