Field trials from 1963 to 1966 showed that UC 21149 (2- methyl-2- (methylthio) propionaldehyde O- (methylcarbamoyl) oxime) applied at planting in furrows at the rate of 16 ounces of active ingredient per acre was the most effective granular systemic insecticide for the control of the green peach aphid, Myzus persicae (Sulzer); the potato aphid, Macrosiphum euphorbiae (Thomas); and the buckthorn aphid, Aphis nasturtii Kaltenbach, on potatoes. One spray of dimethoate in mid-August was necessary for effective control of aphids in disuIfoton- and phorate-treated plots in 1963 when aphid populations were building up but not in 1966 when populations were stationary. Three sprays of oxydemetonmethyl the first at 0.24, the second at 0.48, and the third at 0.72 oz, or 3 sprays at 0.48 oz active ingredient per acre were the most effective of the insecticidal spray treatments.
