This regulation establishes tolerances for residues of acetochlor, including its metabolites and degradates, in or on cotton, gin byproducts; cotton, undelinted seed; soybean, meal; and soybean, seed. Monsanto Company requested these tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA).
