The following herbicides can be selected: 15% propargyl WP, mainly controlling many kinds of grass weeds, wide control spectrum, strong permeability, longer grass age, weeds can be controlled at 2~8 leaf stage after wheat, but the weeds at 2~4 leaf stage are the best. 20~30 grams per mu, mixed with 30 kilograms of water for spraying. Fu-Ning + Qu-Yu, i.e. fluazuron-methyl 70% water dispersible granules plus propargyl ester 15% micro emulsifiable concentrate It mainly controls annual and perennial grass weeds.
