摘　　要：苹果红蜘蛛作为北方主要果树虫害,近几年发生逐渐加重。为了延缓其抗药性增加,对三唑锡悬浮剂防治苹果红蜘蛛的效果进行了试验。结果表明,与25%三唑锡可湿性粉剂相比,20%三唑锡悬浮剂在水中分散性良好,在1000~1500倍试验剂量下,防效均大于95%,且对苹果树安全。三唑锡悬浮剂可以作为防治苹果树红蜘蛛的轮换与替换农药。As a major fruit tree pests in north China,European red mite had gradually increased in recent years.To delay the increase of drug resistance,the control effect of Azocyclotin suspension on European Red Mite was tested.The result showed that compared with 25% Azocyclotin wettable powder,20% Azocyclotin suspension had good dispersibility in water.The control effect of 20% Azocyclotin suspension was more than 95% at 1000-1500 times of test dose,and it was safe for apple trees.Azocyclotin suspension can be used as a rotation and replacement pesticide to control red mite in apple trees.
