甜菜夜蛾药剂防治技术研究

Studies on the technique of controlling beet armyworm with some insecticides

室内和田间试验结果表明 ,新型药剂富锐 18 1Ec、美满 2 4F对甜菜夜蛾具有良好的防治效果 ,可作为当地防治甜菜夜蛾的首选药剂使用 ;米满 2 0F防效好但速效性差可在一般发生年份使用 ;歼灭、高效灭百可、农地乐等速效性较好 ,但对高龄幼虫效果差 ,可与其他药剂交替作用。富锐 5 0 0 0倍与辛硫磷 15 0 0倍、米满 2 0 0 0倍与高效氯氰菊脂 2 0 0 0倍液混合使用 。

Experiments were conducted to study the technique of controlling beet armyworm( Spodoptera exigua Hb.)with some insecticides.The results showed that insecticides such as Fury?Runer can be used as best insecticides in pest control;Mimic,which has high efficiency,but slower killing speed,can be used as regular pesticide when the pest occurs slowly;Springtac,Chinmix and Nurelle can be used alternatively with other insecticides.In order to prevent the resistance,the insecticides such as Fury and Phoxim,Mimic and beta cypermethrin can be used together.
