For the control of broad-leaved weeds in wheat fields, phenoxyacetic acid herbicides (such as 2,4-dibutyl or 2 methyl chloride), benzoic acid herbicides (such as paraquat and its mixtures), and nitrile herbicides can be selected. Agents (such as bromobenzonitrile or iodobenzonitrile), sulfonylurea herbicides (such as thifensulfuron), and heterocyclic herbicides (such as imazapine). Broad-leaved weeds and monocotyledon weeds can be substituted for urea herbicides (such as green wheat, isopropylon, and liguron, etc.); wild oats can be used alone, and oat, Herbicides such as grass grass, wild swallowtail, or oat foe; when wild oats are used as well as broadleaf weeds, wild swallowtail can be used in combination with 2,4-dibutyl ester.
