用途简介


磺酰脲类除草剂,通过阻碍缬氨酸及异亮氨酸合成,从而抑制细胞分裂及细胞的长大。用药手生长停止,5~10d植株开始黄化、枯萎、死亡。可用于插秧稻、直播稻及秧田,防除一年生阔叶杂草及莎草科杂草。用于插秧田在水稻插秧后4~7d用20%水分散粒剂90~150g/hm2 (有效成分18~30g),进行叶茎喷雾或撒毒土(沙)处理,处理后保持田水3~5d,防除鸭舌草、节节菜、萤蔺、眼子菜、牛毛毡、三雄沟繁缕。用于直播田,在水稻播种后7~15d,用20%水分散粒剂90~150g/hm2 (有效成分18~30g)进行撒毒土或喷雾,处理后保持田水3~5d。醚磺隆还可用于可可、橡胶、棕榈园中防除一般杂草和蕨类杂草。
