2.5三氟氯氰菊酯微胶囊剂防治菜青虫田间药效试验

摘要

In order to validate the control effect of cyhalothrin CJ to the cabbage caterpillar,three doses of 2.5% cyhalothrin CJ and reference of 2.5% cyhalothrin EC and blank test had been done.The result showed that 2.5% cyhalothrin CJ had good control effect,it was superior than that of 2.5% cyhalothrin EC,and held the longer effective date.It was a worth extending high-efficiency and low toxicity pesticide.%为验证2.5%三氟氯氰菊酯微胶囊剂对菜青虫的防治效果,设计了2.5%三氟氯氰菊酯微胶囊剂3个不同剂量与2.5%三氟氯氰菊酯乳油及清水对照试验。结果表明：2.5%三氟氯氰菊酯微胶囊剂对菜青虫具有较好的防治效果,优于对照药剂2.5%三氟氯氰菊酯乳油,并且持效期较长,是值得推广的一种高效低毒杀虫剂。
