摘　　要：在番茄幼苗移栽时,将噻虫嗪内吸性杀虫剂包囊于缓释载体之中制成颗粒,施入移栽穴内,能有效地防治番茄白粉虱。在移栽后110d内,0.5%噻虫嗪缓释颗粒在剂量4.0kg/667m2时对白粉虱幼虫和成虫的平均防效分别为74.5%和77.9%;而用相当药剂量的25%阿克泰水分散粒剂处理,对白粉虱幼虫和成虫的平均防效分别为50.5%和56.5%。噻虫嗪缓释颗粒还能有效地减少煤污病的发生。The controlled-release formulation of thiamethoxarn was added in soil when tomato seedlings were planted in order to control Trialeurodes vaporariorurn. The control effects of thiamethoxam in controlled-relase formulation against the larvae and imagoes were 74. 5% and 77.9% respectively, and those of thiamethoxam in water dispersible granule formulation against the larvae and imagoes were 50. 5 % and 56.5 respectively when both two formulations were at the same dosage. Otherwise, thiamethoxam in controlled-release formulation had better effect to control tomato sooty blotch dis- ease than that in water dispersible granule formulation.
