摘要
【目的】筛选出适合新疆南疆阿克苏地区棉花生产上防控棉叶螨的药剂,对棉叶螨进行有效防控。【方法】通过对南疆阿克苏地区主要叶螨截形叶螨Tetranychus truncatus、敦煌叶螨Tetranychus dunchuangensis开展田间药效试验,分析9种药剂对新疆阿克苏地区棉叶螨的药效情况。【结果】敦煌叶螨药后3 d 30%乙唑螨腈悬浮剂、24%联肼·螺螨酯悬浮剂、40%稻丰·仲丁威乳油剂均效果较好,其中30%乙唑螨腈悬浮剂稀释3000倍后防效达到了97.21%,另外10%阿维菌素悬浮剂稀释2000倍后在药后5 d时防效达到了98.13%,显著性高于其他8种药剂的防效;在防治棉田截形叶螨时,药后3 d 10.5%阿维·哒螨灵微乳剂、22.4%螺虫乙酯悬浮剂均较好的效果较佳,其中10.5%阿维·哒螨灵微乳剂稀释2500倍后防效达到了91.16%,显著性高于其他7种药剂的防效。【结论】在棉叶螨发生初期,在生产上轮换使用40%稻丰·仲丁威乳油剂、24%联肼·螺螨酯悬浮剂、30%乙唑螨腈悬浮剂、10%阿维菌素悬浮剂这4种药剂防治敦煌叶螨,轮换使用10.5%阿维·哒螨灵微乳剂、22.4%螺虫乙酯悬浮剂2种药剂防治截形叶螨。
【Objective】To effectively control cotton spider mite,this study will be conducted to screen suitable acaricides for the prevention and control of cotton spider mite in the cotton production of the area.【Methods】Field efficacy trials were carried out on the main mite species in the Aksu area of southern Xinjiang,namely the Tetranychus truncatus and the Tetranychus dunhuangensis Wang,to determine the acaricidal efficacy of nine chemical agents against cotton spider mite in the area.【Results】The research findings revealed that T.dunchuangensis responded exceptionally well to treatments with 30% Tolfenpyrad Suspension Concentrate,24% Bifenazate spiralate Suspension Concentrate and 40% Phenthoate Fenobucarb Emulsifiable concentrates emulsion after three days.Among them,a 3,000-fold dilution of the 30% etoxazole Suspension control efficacy reached 97.21%.Additionally,a 2,000-fold dilution of the 10% abamectin suspension reached a control efficacy of 98.13% at 5 days post-application.,significantly surpassing the performance of the other eight agents tested.Furthermore,in the management of T.truncatus in cotton fields,the 3-day application of 10.5% Abamectin pyridaben Micro-emulsion and 22.4% spirotetramat ethyl ester Suspension Concentrate presented exceptional results.Among them,2500-fold dilution of the 10.5%Abamectin pyridaben microemulsion yielded a control efficacy of 91.16%,significantly outperforming the remaining seven drugs evaluated.【Conclusion】It is recommended that at the onset of cotton mite occurrence,a rotation of four acaricides in production is used to control T.dunchuangensis:40% Phenthoate Fenobucarb Emulsifiable concentrates,24% Bifenazate spiralate Suspension Concentrate,30% Tolfenpyrad Suspension Concentrate,and 10% Avermectin Suspension Concentrate.For the control of T.truncatus,a rotational use of 10.5% Abamectin pyridaben Micro-emulsion and 22.4% spirotetramat ethyl ester Suspension Concentrate is suggested.
