Description

包含R型吡啶氧基羧酸衍生物的除草组合物及其应用 技术领域
本发明属于农药领域,具体涉及一种包含R型吡啶氧基羧酸衍生物的除草组合物及其应用。
背景技术
化学除草是农田杂草防除中最为经济、有效的手段,但长期连续高剂量地使用单一品种或单一作用方式的化学除草剂,容易造成杂草耐药和抗性演化等问题。除草剂化合物的合理复配或混配具有扩大杂草谱、提高防除效果、延缓杂草耐药性和抗药性的发生与发展等优点,是解决上述问题的最为有效的方法之一。因此生产上仍需开发安全性高、杀草谱广、能够产生增效作用并解决抗性杂草问题的除草组合物品种。
发明内容
为解决现有技术中存在的上述问题,本发明提供一种包含R型吡啶氧基羧酸衍生物的除草组合物及其应用。该组合物能有效防除作物田中的各种杂草问题,具有扩大杀草谱、减少施用量、能够产生增效作用并解决抗性杂草等特点。
