摘要
[目的]筛选防治设施桃二斑叶螨的高效杀螨剂。[方法]对设施桃开展田间小区药效试验,分析6种常用杀螨剂对桃二斑叶螨的防治效果。[结果]43%联苯肼酯悬浮剂对桃二斑叶螨卵、幼若螨和成螨均表现出良好防效;其次,30%乙唑螨腈悬浮剂对桃二斑叶螨卵、幼若螨和成螨防效较好。[结论]防治设施桃二斑叶螨的首选药剂为联苯肼酯;乙唑螨腈可轮换使用;三唑锡、螺螨酯、乙螨唑和矿物油对二斑叶螨防效较低,不能有效的控制设施桃二斑叶螨。
[Aims]This study aims to screen out the best acaricides to control Tetranychus urticae Koch in greenhouse peach.[Methods]Field plot trials were carried out on peach to analyze the control efficacy of 6frequently used acaricides against T.urticae.[Results]Bifenazate 43%SC exhibited excellent control efficacy against the eggs,nymphs,and adults of T.urticae,while cyetpyrafen 30%SC showed good control efficacy against the eggs,nymphs,and adults of T.urticae.[Conclusions]Bifenazate is the preferred acaricide for controlling T.urticae in greenhouse peach,cyetpyrafen can be used as a rotational pesticide,but azocyclotin,spirodiclofen,etoxazole and petroleum oil with low activity can′t effectively control T.urticae in greenhouse peach.
