灭幼脲三号是一种昆虫生长调节剂,它能抑制昆虫表皮几丁质的形成,使昆虫不能正常脱皮、变态而死亡。经试验证明,该药具有高效、低毒、残效期长,对人畜安全,不污染环境,不伤害天敌等特点。灭幼脲三号还能够工厂批量生产,成本低、抗淋溶。它既具备生防制剂的的优点,又克服了生物制剂的不足。为此,于1985～1986年与辽阳市美国白蛾防疫站共同主持,在全省组织了利用灭幼脲三号防治美国白蛾试验网点,先后在大连市、丹东市绿化处,本溪市美国白蛾防疫站,本溪市绿化处,新金、宽甸、凤城、金县等地进行了小区套袋试验,小面积防治试验和大面积推广 Chlorbenzuron III is an insect growth regulator, which can inhibit the formation of insect epidermal chitin, so insects can not be normal peeling, metamorphosis and death. The test proved that the drug has high efficiency, low toxicity, long residual period, the safety of humans and animals, do not pollute the environment, do not hurt the natural enemies and other characteristics. Chlorpyrifos on the 3rd can also be mass-produced factory, low cost, anti-leaching. It not only has the advantages of biological control agents, but also overcome the shortcomings of biological agents. To this end, from 1985 to 1986 and Liaoyang City, the United States White Moth Epidemic Prevention Station co-chaired the use of mefloxacin in the United States organized the control of the United States white moth test network, in Dalian, Dandong City Green Department, Benxi City, the United States White moth Epidemic Prevention Station, Benxi City Afforestation Department, Xinjin, Kuandian, Fengcheng, Jinxian and other places bagging plots, small area control trials and large-scale promotion
