Field control efficacy of 6 acaricides against Tetranychus urticae Koch in greenhouse peach
[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 6 frequently 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.
