Effects of three 10% granular systemic insecticides, disulfoton, carbofuran, and TemikĀ® (UC-21149) (2-methyl-2- (methyIthio)propionaldehyde O-(methylcarbamoyl)oxime) , were evaluated for control of the aphids Eulachnus agilis (Kaltenbach) and Cinara Pinea (Mordvilko) on Scotch pine. Temik and disulfoton were applied in circular and broadcast applications, while carbofuran was applied only as a circular application. In the broadcast application, the granular materials were applied at 56.0, 112.0, and 224,0 kg/hectare, and in the circular application at 22.3, 44.5, and 66.9 g/cm of trunk diameter. The aphid population was sampled weekly from the end of May to December 1966. Temik gave complete control from the 1st sampling date throughout the season. The performances of disulfoton and carbofuran were not equal to that of Temik.
