Control Efficiency of Seven Insecticides against Frankliniella tenuicornis (Uzel)
[Objective] The aim was to screen efficient and low-toxicity insecticides which had good control effect on F.tenuicornis.[Method] Control effects of seven insecticides on F.tenuicornis in field were studied.[Result] The seven tested insecticides could kill the most of F.tenuicornis.The control efficiency of Spinetoram was the highest,and it reached 84.30％ three days after treatment,83.30％ seven days after treatment and 82.34％ 14 days after treatment.The control efficiency of Spinetoram and Cyantraniliprole were both more than 80％,furthermore there was no significance between them.[Conclusion] In is suggested that Spinetoram and Cyantraniliprole could be sprayed at the incipient stage of F.tenuicornis to reduce them.
