This regulation establishes tolerances for residues of Cloquintocet-mexyl (acetic acid [5-chloro-8-quinolinyl) oxy]-1- methylhexyl ester) in or on teff when cloquintocet-mexyl is used as an inert ingredient (herbicide safener) in pesticide formulations containing pyroxsulam. Dow AgroSciences LLC requested these tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA) in order to cover residues of cloquintocet-mexyl in imported teff commodities.
