摘要
[目的]研究几种三氯杀螨醇替代杀螨剂对苹果害螨的防效。[方法]研究了3种低毒、低残留杀螨剂对苹果树螨害的防效,并对其田间应用效果进行了评价。[结果]5%唑螨酯、15%哒螨灵乳油和12.15%阿维·三唑锡防治苹果螨害平均防效分别为74.84%、71.22%、58.19%,施药后第7天防效最好,分别为99.46%、99.09%、98.83%,处理间差异不显著,3种杀螨剂对苹果螨害均有较好的防治效果。从速效性分析,15%哒螨灵乳油均优于5%唑螨酯、12.15%阿维·三唑锡,差异性达到极显著,防治后第1天分别为47.60%、45.10%、20.36%。3种杀螨剂施药后对果园害螨天敌均有一定影响,施药后第7天对天敌的消除率分别为31.9%、75.6%、91.8%。[结论]5%唑螨酯悬浮剂对果园天敌影响较小,哒螨灵乳油次之,阿维·三唑锡复方药剂相对影响较大。
[Objective] The aim was to study the control effect of three kinds of dicofols substituting for acaricide on apple acarus.[Method]The control effect of three kinds of low-toxicity and low-persistent acaricide on apple trees acarus was studied,and the application effect was evaluated.[Result] The result of the test indicated that the average control effects on apple trees acarus control of using fenpyroximate(5%),pyridaben E.C(15%) and abamectin-azocyclotin (12.15%) were 74.84%,71.22%,8.19% respectively.The best control effects were 99.46%,99.09%,98.83% respectively after 7 days of using the pesticide,which showed little distinguish between test groups.All three kinds of acaricides had certain extent of effects on natural enemy of orchard acarus.The eliminate ratios were 31.9%,75.6%,91.8% respectively after 7 days of using the pesticide.[Conclusion] The fenpyroximate suspending agent(5%) had the least effect on natural enemy while the abamectin-azocyclotin polypharmaceutical(12.15%) had the most effect.
