吡氟草胺

吡氟草胺用途

【用途一】
本药剂具有以下特点：杀草谱广；可防除恶性杂草；土壤中药效期长；药效稳定；可与其他除草剂混配。药剂施用后，在土表形成一层抗淋溶的药土层，并在作物整个生长期保持活笥，当杂草萌发通过这一药土层时，接触并吸收药剂，杂草根系若接触到药土层，也可吸收。药剂作用能否发挥取决于药剂能否均匀地覆盖地表。在土表或离土表很近的杂草种子发芽后，通过幼芽和根系两个途径吸收药剂。当药剂向上传递时，使幼芽脱色或白化，最后整个植株萎蔫死亡。药剂严重抑制类胡萝卜素的生物合成而使植物产生脱色现象，并间接地破坏光合作用。使用速度与光的强度直接有关。老的植物组织会因新叶的光合作用受抑制而最终受影响死亡。可在杂草芽前或芽后使用。适用作物如小麦、水稻、豌豆、白羽扁豆、胡萝卜、向日葵等。可防除很多杂草。如茜草科（猪殃殃、西洋茜草），玄参科（婆婆纳），堇菜科（三色紫罗兰），苋科（苋菜），石竹科（繁缕），唇形科（黄鼬瓣花），锦葵科和蓼科植物。相反，对伞形科（胡萝卜）和菊科的一些属，几乎无效。总之，能防除绝大部分一年生阔叶杂草，对禾本科莎草也有效。如与其他适用禾本科除草剂混用，可扩大杀草谱。
【用途二】
该品属于类胡萝卜素生物合成抑制剂，是广谱的选择性麦田除草剂。防除禾本科和阔叶杂草，尤其是猪殃殃、婆婆纳和堇菜杂草。
