Excerpts from the report: This report presents results of a small-bin, intermediate-type experiment with wheat protectants. The treatments studied were low-volume (LV) spray and drip-on applications of malathion, an ultra-low volume (ULV) application of a chemically active insecticide, Gardona, and a formulation of malathion in granular carbon for protection against insect attacks. All malathion treatments were applied at the standard dosage rate of 10.42 parts per million technical malathion. The primary objectives of this study were (1) to determine the effectiveness of different formulations and methods of application of malathion and a chemical, Gardona, as protectants of Hard Winter wheat against insect attack and (2) to record the residues remaining on the wheat at selected intervals during 12 months' storage.
