本所于1958年用上海农业药械厂的敌百虫原粉在田间实际应用中,发现具有应用范围广、药效迅速、使用安全的三大特点。为促使敌百虫能在国内大量生产及早支援农业生产大跃进的需要,兹参照有关文献将我们实际应用的点滴经验介绍如下,以供读者参考。 一、敌百虫的化学成分和性状 敌百虫是一种新的有机磷杀虫剂。纯粹的敌百虫是白色结晶固体,融点81℃,比重1.73,工业纯度的敌百虫也是白色固体;但含微量油状杂质,融点在70℃左右,略具挥发性气味,能溶解在水中,每100分水可
The Institute in 1958 with the Shanghai Agricultural Machinery Factory trichlorfon original powder in the field of practical application and found to have a wide range of applications, rapid efficacy, the use of three safety features. In order to facilitate the mass production of trichlorfon in China and to support the great leap forward in agricultural production as early as possible, we refer to the relevant documents as follows for our practical experience. First, the chemical composition and properties of trichlorfon Trichlorfon is a new organophosphate insecticide. Pure trichlorfon is a white crystalline solid, melting point 81 ℃, the proportion of 1.73, the industrial purity of trichlorfon is also a white solid; but with traces of oily impurities melting point at about 70 ℃, slightly volatile odor, can dissolve in water, Every 100 minutes of water can be
