摘要
为筛选出防治大豆斜纹夜蛾的有效药剂,在斜纹夜蛾低龄幼虫发生高峰期用药,进行田间试验,测定乙基多杀菌素等4种生物农药和茚虫威、虫螨腈等6种化学农药对斜纹夜蛾的防治效果。结果表明:生物农药60 g/L乙基多杀菌素SC防效最好,药后3 d、10 d对斜纹夜蛾的防效分别为89.05%、93.77%。化学农药240 g/L虫螨腈SC、30%茚虫威WG、24%甲氧虫酰肼SC防效较好,药后3 d、10 d的防效均超过90%。
To screen out effective insecticides aganist Prodenia litura in soybean field, field trials were carried out with four kinds of biological insecticides and six kinds of chemical insecticides. The results showed that spinetoram 60 g/L SC could control Prodenia litura effectively, the control effects on the third day and the 10th day after spraying were 89.05%and 93.77%. The control effects of chlorfenapyr 240 g/L SC, indoxacarb 30% WG, methoxyfenozide 24% SC were more than 90% on the third day and the 10 th day after spraying.
