筛选棉花蕾期和铃期防治绿盲蝽药剂的研究

有效控制棉花蕾期和铃期绿盲蝽的发生为害，是保铃增产的关键环节，本研究针对生产实践筛选几种质优价廉的常规农药品种及科学混配药剂，进行了田间药效试验。结果表明：马拉硫磷、吡虫啉、高效氯氰菊酯+毒死蜱和高效氯氰菊酯+氧化乐果复配药剂在蕾期和铃期对绿盲蝽的防治效果较好，且复配药剂具有一定的增效作用，但马拉硫磷持效期较短。现予以整理报道，供大规模控制绿盲蝽危害提供参考。

The Study on Screening the Effective Insecticides on Lygus lucorum Meyer-Dür at flower stage and boll stage of cotton

The aim was that effectively controlling the Lygus lucorum MeyerDur at flower stage and boll stage for protecting the boll and improving the products of cotton. On this study, we screened several qualified and economic common insecticides and scientific mixture to deploy by spraying in anxin cotton field. The results indicate that the controlling effect came to better of malaliulin, imidacloprid, synergistic mixture beta-cypermethrin plus Chlorpyrifos and omethoate mixed beta-cypermethrin at flower stage and boll stage, respectively. And we found there is a synergized action in the synergistic mixture, and the malaliulin durable effect is shorter than other pesticides. This paper will provide a reference to cosmically controlling the cotton plant bugs.
