This regulation establishes tolerances for the combined residues of the insecticide diflubenzuron (N-[[4-chlorophenyl)amino]- carbonyl]-2,6-difluorobenzamide) and its metabolites, 4- chlorophenylurea (CPU) and 4-chloroaniline (PCA) in or on the following raw agricultural commodities: Grass, forage, fodder, and hay group 17 at 6.0 ppm; pepper at 1.0 ppm; stone fruit group 12 (except cherries) at 0.07 ppm; nut, tree, group 14 at 0.06 ppm; almond, hulls at 6.0 ppm; pistachio at 0.06 ppm; cattle, meat byproducts at 0.15 ppm; goat, meat byproducts at 0.15 ppm; hog, meat byproducts at 0.15 ppm; horse, meat byproducts at 0.15 ppm; sheep, meat byproducts at 0.15 ppm. This regulation is increasing the tolerance level for meat byproducts of cattle, goat, hog, horse, and sheep. This regulation is also changing the tolerance on pasture grass to grass, forage, fodder, and hay group 17. Interregional Research Project Number 4 (IR-4), and Uniroyal Chemical Company requested these tolerances under the Federal Food, Drug, and Cosmetic Act, as amended by the Food Quality Protection Act of 1996.
