除草剂在麦地除草中发挥了重要作用,但从近年的使用情况看,如果不按要求使用,便会造成药害,使小麦叶片发黄。乙羧氟草醚在一些地方使用10%苯磺隆可湿性粉剂时,往往会加入助剂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草死亡。而乙羧氟草醚为触杀性除草剂,能防 Herbicides play an important role in the weed control of wheat fields. However, in recent years, if they are not used as required, they will cause phytotoxicity and yellow the wheat leaves. Chlorfluazuron 10% triasulfuron in some places when wettable powder, tend to join the auxiliary 10% fenofibrate 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 cells from dividing and leaving weeds dead. Butaflufen is a contact herbicide, can prevent
