近年我省棉蚜危害猖獗.由于棉蚜对现有几种化学农药产生了抗药性,市场上又没有新的高效低毒农药,致使在棉花生产上采取盲目加大药液浓度和增加防治次数,往往造成药害和人力、物力浪费.经试验,近二年从美国进口防治水稻等作物害虫的新农药呋喃丹(Furadan)对防治棉蚜效果显著. In recent years, cotton aphid in our province is rampant because cotton aphid has developed resistance to several existing chemical pesticides and there is no new highly effective and low toxicity pesticide on the market, resulting in blindly increasing liquid concentration and increasing the number of control , Often resulting in phytotoxicity and manpower, material and waste.After the test, Furadan, a new pesticide imported from the United States to control crop pests such as rice in recent two years, has a significant effect on the control of cotton aphid.
