A plot with monocotyledonous weeds such as brome. As dominant weeds: 3% methyl disulfonate oil suspension 20-30ml, 7.5% sulfanilamide (priority) water dispersible granules12-65438+2-3g adjuvant 70-80ml or 70% sulfuron-methyl (Hu Biao) water dispersible granules 2 per mu.
Weedy land dominated by Aegilops tauschii: 30 ml of 3% methyl disulfonate (Shima) oil suspending agent and special additives are used per mu.
Mixed sowing of monocotyledonous and dicotyledonous weeds in wheat field: 3-3.6g of 12% melamine or wheat+wheat and 70% sulfuron-methyl water dispersible granules can be used per mu.
Plot mixed with broad-leaved weeds: The compound preparation of melamine (0.5% fomesafen+10% fluroxypyr+1.5% carfentrazone) can expand the weed control spectrum, improve the control effect, and effectively control weeds such as descurainia sophia, shepherd's purse, swiftlet and wheat straw.
Descendants, descurainia sophia, shepherdess, shepherdess, shepherdess, shepherdess, shepherdess, shepherdess, shepherdess and shrubbery are resistant to sulfonylurea herbicides such as tribenuron-methyl, and the maximum dosage is 50-75ml/ mu.
