摘要
采用不同剂量的25 g/L高效氯氟氰菊酯EC进行甘蓝菜青虫防治试验,验证其防治效果,确定最佳剂量。结果表明,25 g/L高效氯氟氰菊酯EC防治菜青虫低龄期的最佳用药量为有效成分9.4 g/hm2,平均防效在94.6%以上。
The control effect of different concentration of 25 g/L Cyhalothrin EC on Preris rapae Linnaeus was studied.The results showed that the best dosages of 25 g/L Lambda-cyhalothrin EC on young Pieris rapae Linnaeus was 9.4 g/hm^2 and the average control effect was above 94.6%.
