CAS: 139-40-2; Propazine

该化合物是一种属于三联苯类的选择性除草剂,主要用于控制各种作物特别是玉米的宽叶素和草杂草,其化学结构具有三联苯环,这是该类许多除草剂的特征.Propazine在植物中抑制光合作用,具体针对光系统II综合体,从而扰乱电子运输链.这会导致目标杂草最终死亡.该物质通常根据具体的农业做法,在出现前或出现后施用.Propazine在水中可中中等溶解,并且具有相对较低的挥发性,有助于其在环境中的持久性.然而,由于潜在的环境影响,包括地下水污染和对非目标有机体的影响,所以许多地区的使用都受到管制.在处理丙胺时,安全措施是必不可少的,因为它可能对人类健康和生态系统构成风险,如果管理不当的话,则会对丙基磺碱产生危害.总的来说,在农业杂草管理中仍然是一个重要的工具,尽管其应用必须加以仔细控制.
