摘要
为验证7.5%除虫·高氯悬浮剂对甘蓝菜青虫防治效果,确定最佳剂量,我们做了田间药效试验,结果表明,7.5%除虫·高氯悬浮剂对甘蓝菜青虫的最佳用量为17￣28ga.i./hm2(有效成分,下同),平均防效在78.1%以上。
Field trials were conducted to validate the efficacy of a 7.5% suspension concentrate package mixture of beta-cypermethrin plus diflubenzuron in control of cabbage caterpillar, and to determine the optimum application rate. For cabbage caterpillar control, the best rate of beta-cypermethrin plus diflubenzuron 7.5% SC was 17 to 28 g a.i./ha. Efficacy averaged 78.1% or higher.
