农药“敌百虫”为一种合成有机磷杀虫剂,由三氯乙醛(氯加酒精)与亚磷酸二甲酯(三氯化磷加甲醇)缩合而成易溶于水。喷(氵丽)0.1％浓度左右的药液,对各种昆虫均有良好兼治作用,对各种圆虫扁虫也有效果。“敌百虫”不仅效能高,价钱便宜,对人畜无巨毒,而且原料和制造都简单方便。除城市工厂内可以大量生产外,在人民公社内亦可生产,因而是一较好的杀虫农药。为了探求“敌百虫”的使用方法,我系对棉虫、谷子害虫、油菜害虫进行了试验,结果证明在较高浓度,0.15％以上时,有良好的渗透内吸杀虫作用。根据:(1)叶面喷(氵丽)防治
Pesticide “Trichlorfon” is a synthetic organophosphorus pesticide, which is easily dissolved in water by the condensation of trichloroacetaldehyde (chlorinated alcohol) with dimethyl phosphite (phosphorus trichloride plus methanol). Spray (氵 Li) 0.1% concentration of the liquid medicine, all kinds of insects have a good both governance role, on a variety of round worm flatworms also have effect. “Trichlorfon” is not only high efficiency, cheap, non-toxic to humans and animals, and raw materials and manufacturing are simple and convenient. In addition to being mass-produced in urban factories, it can also be produced in people’s communes and is therefore a better pest-killing pesticide. In order to explore the use of “trichlorfon”, I conducted tests on cotton insects, millet pests and rape pests. The results showed that there was a good osmotic insecticidal effect at higher concentrations above 0.15%. According to: (1) foliar spray (氵 Li) prevention and treatment
