Abstract:Diazinon was applied to wheat as an emulsion from 0.25 to 2.0 lb/1000 bushels, and the treated grain then stored in open containers for 130 days. Grain samples were removed at intervals to determine the external and internal diazinon residues on the grain, as well as the distribution in 3 milled fractions: bran, shorts, and flour. Diazinon was found to penetrate to the interior of the grain with a stable level reached at about 45 days. Residue dissipation beyond this period was extremely slow. Distribution of diazinon in the milled fractions showed more than half of the insecticide in the bran at 24 hours (57%), while the shorts contained 26%, and the flour the least amount (17%). At the longer posttreatment intervals diazinon residues decreased in the bran with a corresponding rise in the shorts and flour. Averages of all treatment rates indicated that about 70% of the theoretical application adhered to the grain and that cleaning, tempering, and milling processes appear to dissipate approximately half of the residue.
