目前,用于麦田的除草剂日益增多,在除草中发挥了重要作用。但是近些年来,从使用情况来看,有些除草剂如果不按要求使用,便会造成药害,使小麦叶片发黄,应引起注意。1、乙羧氟草醚。在一些地方使用10%苯磺隆可湿性粉剂,往往会加入助剂,这种助剂大多数是用10%乙羧氟草醚乳油。苯磺隆是磺酰脲类内吸传导型芽后选择性除草剂,茎叶处理后可被杂草茎、叶吸收,并在体内传导,通过阻塞乙酰乳酸合成酶,使缬氨酸、异亮氨酸的生物合成受到抑制,阻止细胞分裂而使杂 At present, the increasing use of herbicides in wheat fields has played an important role in weeding. However, in recent years, from the point of view of usage, some herbicides may cause phytotoxicity if they are not used as required, causing the yellowing of wheat leaves to attract attention. 1, B fluoride fluoride grass ether. In some places using 10% tribenuron-methyl WP, often will add additives, most of this additive is with 10% fenoflurane EC. Tribenuron-methyl is a sulfonylurea-type conduction-induced post-emergence selective herbicide that can be absorbed by the weed stems and leaves and processed in the body after stems and leaves treatment. By blocking acetolactate synthase, Leucine biosynthesis is inhibited, preventing cell division and miscellaneous
