摘　　要：为探寻鄄城县玉米螟有效的防治药剂,于当地进行了田间试验。以‘郑单958’玉米品种为试验材料,设置了3个不同的药剂处理及1个清水对照处理,比较不同处理玉米螟防治效果、挽回产量损失率及产量情况。结果表明:40%氯虫·噻虫嗪水分散颗粒剂、22%甲氧肼·氯虫苯悬浮剂、10%甲维高氯氟微囊悬浮剂等3种药剂在施用2次后,对玉米螟均具备一定的防治效果,其防治效果整体超过了60%;其中,以40%氯虫·噻虫嗪水分散颗粒剂防治效果最佳,平均防效达到了90.67%,挽回产量损失率达到了7.87%,较不施药处理增产10.47%,是最适宜的防治药剂。因此,建议在鄄城县玉米螟防治中大力推广及应用40%氯虫·噻虫嗪水分散颗粒剂。To explore effective control agents for corn borers in Juancheng County,field trials were conducted locally.Taking the'Zhengdan 958'corn variety as the experimental material,three different pesticide treatments and one clear water control treatment were set up to compare the control effects on corn borers,the yield loss recovery rate,and the yield situation.The results showed that after the second application,40%chlorantranyl thiamethoxam water-dispersible granules,22%methoxyhydrazidechlorantranyl suspension concentrate,and 10%emamectin perchlorofluorine microcapsule suspension concentrate all had certain control effects on corn borers,,with overall control effects exceeding 60%.Among them,40%chloranthroxam thiamethoxam water-dispersible granules had the best control effect,with an average efficacy of 90.67%,a yield loss recovery rate of 7.87%,and a yield increase of 10.47%,compared to the untreated control,making it the most suitable control agent.Therefore,it's recommended to vigorously promote and apply 40%chlorantranyl thiamethoxam water-dispersible granules in the control of corn borer in Juancheng County.
