C)大田示范
利用实施例1-85制得的除草组合物进行田间杂草效果试验。2017年在山东黄岛试验点进行示范性推广试验。田间发生的杂草主要有：稗草、马唐、绿色狗尾草、牛筋草、反枝苋、马齿苋、粟米草、水莎草，等等。
试验方法：
茎叶处理(F)：待杂草处于2-3叶期，手动喷雾器，兑水量30公斤/667m 2，采用茎叶喷雾均匀喷雾。
土壤处理(S)：于杂草发芽前，手动喷雾器，兑水量45公斤/667m 2，采用土壤表面均匀喷雾。
具体试验药剂及剂量详见表86，小区面积20平方米，每处理重复3次。施药后20天调查防除效果见表86。

经过大量试验和探索，本发明意外地发现，所述组合物用于防除主要禾本科杂草、阔叶杂草及莎草科杂草等，具有令人惊讶的、意想不到的增效作用，这种增效作用在低剂量下表现更为显著，可降低用药量，降低对环境的污染，且合理复配降低了农用成本，对ALS、ACCase抑制剂抗性杂草高效，具有很好的应用前景。同时经过测试在小麦田、玉米田、水稻田、花生、甘蔗、高粱、谷子、马铃薯、油菜、大豆、棉花、蔬菜、早熟禾、高羊茅、结缕草等植物显示良好的选择性和优异的增效作用，可以开发成具有广泛市场价值的除草剂混剂。
