摘要
为明确10%四氯虫酰胺悬浮剂对甜菜夜蛾的防治效果,开展了室内毒力测定和田间药效评价。结果表明:四氯虫酰胺对甜菜夜蛾具有较好的防治效果,95%四氯虫酰胺原药对甜菜夜蛾的LC50值为0.123 7 mg/L。10%四氯虫酰胺悬浮剂有效成分用量为30~60 g/hm^2时,药后3 d、7 d、10 d对甜菜夜蛾的田间防治效果大于90%。
In order to provide the basis for the new pesticide application, the control of effect silv chong xian’an 10% SC to Spodoptera exigua were studied in laboratory and field trails. The results showed that Silv chong xian’an had good control effects on Spodoptera exigua, and LC50 value was 0.334 5 mg/L. The control effects of silv chong xian’an 10% SC30-60 g/hm^2 were more than 90% on the third day, seventh day and the tenth day after spraying.
