| Abstract: | Field-tests with 25% pymetrozine WP at 62.5-250ppm to control three species of aphid were conducted in 1998.The results demonstrated that 25% pymetrozine WP was effective for control of the three pests.For Macrosiophum avenae (Fabricius)and Acyrthosiphon porosus (Sqnderson) the control efficacy was similar to or better than that of alphacypermethrin 5EC at 25ppm,but the efficacy was lower than that of alphcypermethrin for Myzus persicae (Sulzer). |
