This regulation revises a use of pyridate on mint (with tolerances on mint, fresh leaves and mint, dried leaves); a crop group expansion to field corn subgroup 15-22C; and a crop group conversion to vegetable, brassica, head and stem, group 5-16, which includes a tolerance on orphan crop kohlrabi. The Interregional Project Number 4 (IR-4) requested this tolerance under the Federal Food, Drug, and Cosmetic Act (FFDCA).
