【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。更多还原

【Abstract】 [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.更多还原
