【摘要】 用1×109PIB/g斜纹夜蛾核型多角体病毒·15%,虫酰肼悬浮剂进行了甘蓝斜纹夜蛾的田间药效试验。结果表明:供试药剂对甘蓝斜纹夜蛾具有良好的防治效果,田间制剂用量1 500 g/hm2时,药后3天对甘蓝斜纹夜蛾幼虫的防效达到80%,以上,且持效期达14 d,显著优于对照药剂1×109PIB/g斜纹夜蛾核型多角体病毒可湿性粉剂1 500 g/hm2的防效和持效期,说明1×109PIB/g斜纹夜蛾核型多角体病毒·15%,虫酰肼悬浮剂在防治甘蓝斜纹夜蛾上具体良好的推广应用前景。更多还原

【Abstract】 Pesticide effect tests using 1×109PIB/g Spodoptera litura nucleopolyhedrovirus·15% Tebufenozide SC against Spodoptera litura Fabricius on cabbage in the field were carried out.The results showed that the Tebufenozide SC has a good effect.After a 3-day spraying of 1 500 g/hm2 pesticide,the control efficacy exceeded 80%,and the persistent period lasted for 14 d,obviously better than those of 1 500 g/hm2 of 1×109PIB/g Spodoptera litura nucleopolyhedro-virus WP.The result indicated that 1×109PIB/g Spodoptera litura nucleopolyhedrovirus·15%,Tebufenozide SC have a good prospect.更多还原
