棉蚜是我省棉花的主要害虫,鉴于近年来棉蚜对有机磷杀虫剂抗药性的日益增强,提高药液浓度和增加施药次数又遭致杀伤天敌和污染环境的问题。1979年我们在裴村大队,对3%呋喃丹(FURADAN 3G,美国产)颗粒剂进行了隐蔽施药防治棉蚜试验示范,面积达120亩次,获得良好效果,并摸索出一些使用方法。通过试验示范,我们认为该药剂是目前棉蚜综合防治中一个理想药剂,具有许多突出的优点,值得扩大示范推广.现将其性能、治蚜效果和使用方法简介于下:
Cotton aphid is the main pest of cotton in our province. In view of the increasing resistance of the cotton aphid to organophosphate insecticide in recent years, the problem of pesticide natural enemies and pollution of the environment caused by increasing the concentration of the medicinal solution and increasing the number of pesticides applied to the cotton aphid.
