皖北地区玉米田草地贪夜蛾防控比对试验分析

Comparative Experiment and Analysis on Control of Spodoptera frugiperda in Corn Fieldin Northern Anhui

本文对3种不同施药机械(背负式电动喷雾机、自走式喷杆喷雾机、植保无人机)和3种药剂(10%甲维·虫酰肼乳油、12%甲维·虫螨腈悬浮剂、9%甲维·茚虫威悬浮剂)对草地贪夜蛾防控效果进行了对比分析,结果显示:3种植保机械、药剂对草地贪夜蛾防控效果均较好无明显差异,其中自走式喷杆喷雾机防效最好,可达92.99%;10%甲维·虫酰肼悬浮剂防效最高,可达到90.2%。建议在实际防控过程中,结合虫龄和作物生育期,因地制宜选择合适的植保机械及防治药剂,有效提高防治效果。

This article compared and analyzed the control effects of the combination of different application machinery(Knapsack electric sprayer,self propelled boom sprayer,plant protection UAV)and pesticides(10%methotrexate+tebufenozide EC,12%Emamectin+fenapyr SC,9%Emamectin+indoxacarb SC)on the control of Spodoptera frugiperda in corn fields.The results showed that the three kinds of machinery and insecticides had no significant difference in preventing and controlling spodoptera litura.Among them,the self propelled sprayer and 10%Methoyl buzide SC had the best control effect,up to 92.99%and 90.2%,respectively.It is suggested that in the actual control practice,taking consideration of insect age and crop growth period,appropriate plant protection machinery and control agents should be chosen to improve the control effect.
