This regulation amends tolerances for residues of clopyralid (3,6-dichloro-2-pyridinecarboxylic acid) in or on sugar beet roots and sugar beet tops. In addition, this regulation establishes a tolerance for sugar beet molasses. Finally, the established tolerances for barley forage and milled fractions of barley, oats and wheat are being added back to the tolerance expression for clopyralid after being inadvertently deleted. Dow AgroSciences LLC requested this tolerance under the Federal Food, Drug, and Cosmetic Act, as amended by the Food Quality Protection Act of 1996.
