Description

一种除草组合物及其应用 技术领域
本发明属于农用除草剂领域，涉及一种除草组合物及其应用。
背景技术
通式I化合物具有很好的除草活性，可以有效地控制稗草、狗尾草、异型莎草、水莎草、马唐、荩草、苘麻、百日草、反枝苋、马齿苋、苍耳、龙葵、决明、野西瓜苗、野大豆等不同叶期的杂草，在低剂量下就可以获得很好的除草效果。
任何一种除草剂的使用，都有其局限性，有机磷类除草剂，特别是草甘膦在使用过程中，也同样存在以下问题：1.部分杂草种群对草甘膦具有天然的耐药性，需要较高的用量或较多的用药次数才能彻底防除，如旋花科的田旋花和打碗花、木贼科的问荆、苋属的铁苋菜、某些豆科杂草、蕨类植物、地下部分繁殖的杂草、竹类和某些灌木等；2.抗性杂草的出现对草甘膦的使用带来了巨大的挑战。目前，尽管我国还未有正式的报道表明草甘膦抗性杂草的出现，但在某些地区已经出现了由于连年使用草甘膦，有些杂草需要很高的剂量才能防除的现象，如小飞蓬，目前已成为长江流域棉花田的优势杂草种群，牛筋草在广东、福建的蔬菜田及果园普遍发生，使用单一的很难防除。
除草剂的混用是扩大杀草谱、降低使用量和使用频率、防止抗性杂草抗性产生和防除抗性杂草的一个有效途径，因此急需一种能够替代单一草甘膦作为活性组分的复配除草剂。
