70年代初,美国孟山都(Monsanto)公司制备了大量氨基甲基膦类化合物,并从中筛选出一个优秀的有机磷除草剂:草甘膦。草甘膦是高效、低毒、低残留、广谱性有机磷芽后除草剂,世界上危害最大的杂草有78种,草甘膦能有效的控制其中的76种,因其性能优越而受到世界农药行业的关注,就在注册的那年(1974),即被美国评为当年最优秀的农药,并被誉为现代农药史上的一个重大发现。目前草甘膦已发展成为最大的除草剂品种。
In the early 1970s, a large amount of aminomethylphosphine compounds were prepared by Monsanto Company in the United States, from which an excellent organophosphorus herbicide, glyphosate, was screened out. Glyphosate is a highly effective, low toxicity, low residue, broad-spectrum organophosphate postemergence herbicide. Among the 78 most weed species in the world, glyphosate can effectively control 76 of them. Because of its superior performance By the world’s pesticide industry attention, just in the year of registration (1974), the United States was rated as the best pesticide of the year, and was hailed as a major discovery in the history of modern pesticides. Glyphosate has now grown into the largest herbicide variety.
