不同药剂防治玉米草地贪夜蛾田间药效试验

Field Efficacy Test of Different Insecticides Against Spodoptera frugiperda of Maize

摘要: 选用20%氯虫苯甲酰胺、14%高效氯氟氰菊酯、15%茚虫威、5.7%甲氨基阿维菌素苯甲酸盐和2.5%敌杀死共计5种药剂，进行草地贪夜蛾田间药效试验。结果表明，5种药剂均对防治草地贪夜蛾有效，且药后安全无药害现象发生。其中，20%氯虫苯甲酰胺防效最好，可达96.68%;14%高效氯氟氰菊酯次之，为93.74%;15%茚虫威、5.7%甲氨基阿维菌素苯甲酸盐和2.5%敌防效分别为92.93%、92.31%、90.63%。

Abstract: Field efficacy tests were conducted on 20% chlorfenamide, 14% cyhalothrin, 15% indocarb, 5.7% amamectin benzoate and 2.5% diphenacide. The results showed that all the five drugs were effective in controlling Spodoptera frugiperda, and there was no harm after taking them. Among them, 20% chlorfenamide had the best control effect, up to 96.68%; Cyhalothrin（14%） was followed by 93.74%; The control effects of 15% indocarb, 5.7% amamectin benzoate and 2.5% were 92.93%, 92.31% and 90.63%, respectively.
