Use of the phosphate triazine insecticide, Guthion® (O, O- dimethyl S-4-oxo-1, 2,3-benzotriazin-3-( 4H)-ylmethyl phosphorodithioate) as a foliar spray for potato insect control has resulted in increased yields of red-skinned potatoes above that normally obtained as a result of efficient insect and disease control. The magnitude of this increase averaged about 15% and was solely attributable to increases in set of tubers. Dry matter and potato grade based on size was not affected. While tuber set of white-skinned potatoes was also increased slightly, results were not significant, and yields were less than those obtained from other plots treated with insecticides.
