近年来,棉铃虫对菊酯类、有机磷农药抗药性逐年加重,棉铃虫防治成为极其严重的问题,对棉花生产威胁极大。为了延缓棉铃虫抗药性的发展,探求对抗性棉铃虫防治效果好的药剂。我们于1991～1992年在冠城镇五里铺、东关、西街、农牧良种场等,对几种新农药进行了药效试验、示范大面积推广,现将两年来的情况总结如下。 In recent years, cotton bollworm to pyrethrins, organophosphate pesticide resistance increased year by year, bollworm prevention and control has become an extremely serious problem, a great threat to cotton production. In order to delay the development of cotton bollworm resistance and explore the effective control agent against cotton bollworm. From 1991 to 1992, we studied the efficacy of several new pesticides in the Wulipu, East Gate, West Street, agricultural and pastoral breeding farms in Guancheng Town to demonstrate the large-scale promotion. The current situation over the past two years is summarized as follows.
