This regulation establishes tolerances for residues of fludioxonil in or on carrots, the stone fruit group 12-12, and the rapeseed subgroup 20A, except flax seed. Interregional Research Project Number 4 (IR-4) requested the tolerances for carrots and the stone fruit group 12-12, and Syngenta Crop Protection requested the tolerance for the rapeseed subgroup 20A under the Federal Food, Drug, and Cosmetic Act (FFDCA).
