目前,中国市场上灭生的除草剂只有百草枯、草甘膦、甲嘧磺隆、三氯吡氧乙酸、草铵膦五种。自从先正达在中国市场上推出百草枯之后,取得了大面积使用,到2016年,百草枯水剂将退出中国的历史舞台。甲嘧磺隆、三氯吡氧乙酸用于非耕地除草剂,主要运用于森林防火、铁路、公路等,不能在农田中使用,对人的危害并不突出,所以,此类产品之寿命会更长久一些,余下的就只有草甘膦与草铵膦。一、百草枯1、1882年,百草枯首度合成。 At present, only herbicides, glyphosate, sulfometuron, triclopyr and glufosinate are the only herbicides killed in the Chinese market. Since Syngenta introduced paraquat in the Chinese market, it has achieved a large area of ​​use. By 2016, paraquat will withdraw from the historical stage of China. Sulfometuron and Triclopyr are used in non-arable land herbicides and are mainly used in forest fire prevention, railways, highways and so on. They can not be used in farmland and their harm to human beings is not conspicuous. Therefore, the life span of such products For longer, the only remaining glyphosate and glufosinate. First, paraquat 1, 1882, paraquat for the first time synthesized.
