柑桔红蜘蛛(Panoychus citri Meg.)在我省一年有17～19代,危害期长,对药剂易生抗性。因而寻找更多的高效低残留、不具交互抗性、既能控制害螨、又能提供防治上轮换使用的新剂型杀螨剂,是当前急需解决的问题。单甲脒为有机氮类药剂,是浙江省工学院化工系合成的具有生物活性的新剂型杀虫杀螨剂,1982～1983年我们使用25％单甲脒水剂1000倍(250ppm)杀伤成若螨达100％,杀卵效果为98.5％,与双甲脒一样,对成、若螨均
Citrus red spiders (Panoychus citri Meg.) 17 to 19 generations a year in our province, the long-term damage, the drug susceptible to resistance. Therefore, looking for more efficient and low residue, not cross-resistance, both to control pests, but also provide a new type of control on the rotation of acaricide, is currently the urgent need to solve the problem. Monoamidine is a kind of organic nitrogenous medicine. It is a new type of biocidal acaricidal and acaricidal agent synthesized by Department of Chemical Engineering, Zhejiang University of Technology. From 1982 to 1983, we used 1000% (250ppm) 25% If mites up to 100%, the ovicidal effect of 98.5%, as amitraz and the same as if the mites were
