Phenoxyacetic acid herbicides (such as 2,4-butyl or 2- methyl -4 chlorine), benzoic acid herbicides (such as paraquat and its mixture), nitrile herbicides (such as bromoxynil or ioxynil), sulfonylurea herbicides (such as thifensulfuron-methyl) and heterocyclic herbicides (such as bentazone) can be used to control broad-leaved weeds in wheat fields. In the mixed field of broad-leaved weeds and monocotyledonous weeds, urea herbicides (such as chlorotoluron, isoproturon, Liguron, etc. ) can be replaced; In the field dominated by wild oats, herbicides such as yetanwei, herbicides, dried wild swallows or yetanfen can be used alone; When wild oats are mainly used and there are also broad-leaved weeds, 2,4-butyl ester can be mixed with wild swallows.
