| 摘 要： | 为了测定和评价20%虫酰肼悬浮剂对甜菜夜蛾的防治效果和安全性,为其推广使用提供技术支持,利用20%虫酰肼悬浮剂对甘蓝甜菜夜蛾幼虫进行了田间药效试验研究。结果表明,20%虫酰肼悬浮剂对甘蓝甜菜夜蛾的防治,在有效成分用量200～300 g/hm2范围内,药后1～2 d防效为83%～99%,药后3～5 d防效为86%～99%,药后7～10 d防效为89%～98%,防效好于对照药剂48%毒死蜱乳油和1%甲氨基阿维菌素苯甲酸盐乳油,其速效性好、持效性较长。20%虫酰肼悬浮剂可以作为防治甘蓝甜菜夜蛾的有效替代药剂进行推广使用,最佳用药量以有效成分用量200～300 g/hm2为宜。

| Abstract: | Experimental test was carried out to measure and evaluate the efficiency and security of Tebunozide 20% SC, which was used to control cabbage beet armyworm, and to provided technical support for its popularization. The results showed that when the dosage of active ingredient was 200 - 300 g/hm^2, the control effect was 83% - 99%, 1 - 2 days after application; 86% - 99%, 3 - 5 days after application and 89% - 98%, 7 - 10 days after application, which was better than those contrasting pesticides Chlorpyrifos 48% EC and Emamectin Benzoate 1% EC in term of rapidly efficiency and long persistent period. As a safe and environmental friendly water-based dosage, Tebufenozide 20% SC could be used as an effective ahemative pesticide to control cabbage beet armyworm, and the best dosage of active ingredient is 200 - 300 g/hm^2. |
