近年开发的含氟除草剂的简要介绍

Brief introduction of several fluorinated herbicides developed in recent years

近10年开发的除草剂品种中,含氟除草剂约占50%,引发人们的大量关注,因其具有高选择性、高适应性、低成本、低毒、低残留、对环境友好等优点,已经成为当代农药的发展趋势。概述了嘧氟磺草胺、氟酮磺草胺等7个最近上市的含氟除草剂品种,并对其化学结构、合成路线、生物活性及作用机理进行了简要介绍。

Among the herbicides developed in the past 10 years, fluorinated herbicides account for about 50%, which has attracted a great deal of attention. Due to its advantages of high selectivity, high adaptability, low cost, low toxicity,low residue, and environmental friendliness, fluorinated herbicides have become the development trend of contemporary pesticides. In this paper, seven recently listed fluorine-containing herbicides were summarized, such as pyrimisulfan and triafamone, and their chemical structures, synthetic routes, biological activities and action mechanisms were briefly introduced.
