| 摘 要： | 目的]研究了几种药剂防治十字花科小菜蛾的药效试验,以筛选出高效、低毒、低残留的农药,促进贵阳市无公害蔬菜生产可持续发展。方法]设天佑(37.5%硫双威悬浮剂)1500倍液、抑太保(5%氟啶脲乳油)1500倍液、虫满克(1.8%阿维菌素乳油)1 500倍液、克蛾宝(15%阿维.辛乳油)1500倍液以及空白对照(CK)5个处理,开展药剂防治小菜蛾的药效试验。药后3、7、15 d,分别在标记的结球甘蓝上调查残存的幼虫活虫量,并计算防治效果。结果]施药后3、7、15 d,克蛾宝1500倍液对小菜蛾防治效果分别达82.4%、81.5%、79.6%,表现出较好的速效性;天佑1500倍液、抑太保1500倍液、虫满克1500倍液对小菜蛾防治效果分别达60.2%以上,但均低于克蛾宝1500倍液的防治效果。方差分析表明,施药后3、7 d,克蛾宝1500倍液的防治效果与天佑1 500倍液、抑太保1500倍液、虫满克1 500倍液处理间差异极显著。施药后15 d,克蛾宝1500倍液的防治效果与天佑1500倍液、虫满克1500倍液处理间差异极显著,与抑太保1500倍液处理间差异显著。结论]克蛾宝(15%阿维.辛乳油)1500倍液是防治十字花科蔬菜小菜蛾的较好农药,是可作为替代常规药剂来防治小菜蛾的新型复配杀虫剂。

| Abstract: | Objective] The research aimed to study the effects of several pesticides controlling Plutella xylostella(L.) of Cruciferae,to screen high effective,low poison and low remnant pesticides,to promote the sustainable development of uncontaminated vegetable production.Method] Five treatments including Tanyou(37.5% thiodicarb SC),Yitaibao(5% chlorfluazuron EC),Chongmanke(1.8% Avermectin EC),Keebao(15% abamectin·phoxim EC) and contrast were designed to make the effect test of controlling Plutella xylostella(L.).The remnant number of larvae was investigated in cabbage(Brassica oleraces var.capitata L.) signed after treated 3,7,15 days.Result] The control effects of Keebao after treated 3,7,15 days were 82.4%,81.5%, 79.6% respectively,and those of Tanyou,Yitaibao and Chongmanke were all over 60.2%,but all less than Keebao.The difference analysis showed that there were significant differences on the control effect between Keebao and Tanyou,Yitaibao and Chongmanke after treated 3,7 days.There were very significant differences on the control effect between Keebao and Tanyou,Chongmanke after treated 15 days,and there was significant difference between Keebao and Yitaibao.Conclusion] Keebao(15% abamectin· phoxim EC) is a good pesticide for controlling Plutella xylostella(L.) of Cruciferae,and also a new type mixed insecticide replacing normal pesticides |
