麦草畏

麦草畏用途

【用途一】
对小麦、玉米等作物中的一季生和多季生阔叶杂草有显著效果
【用途二】
安息香酸系除草剂（苯甲酸类）。具有内吸传导作用，对一年生和多年生阔叶杂草有显著防效。用于小麦、玉米、谷子、水稻等禾本科作物防除猪殃殃、荞麦蔓、藜、牛繁缕、大巢菜、播娘莴、苍耳、薄朔草、田旋花、刺儿菜、问荆、鲤肠等。苗后喷雾，药剂通过杂草的茎、叶、根吸收，通过韧皮部及木质部上下传导，阻碍植物激素的正常活动，从而使其死亡。一般用48%水剂3～4.5mL/100m² (有效成分1.44～2g/100m² )。由于麦草畏杀草谱较窄，对某些抗性杂划效果不佳。对小麦安全性较小，常与2，4-滴丁酯或2甲4氯胺盐混用。
【用途三】
用作植物发芽后的除草剂。常与一种或多种苯氧羧酸类除草剂或其他除草剂混合加工成混剂，用于谷物地除草。
