摘 要：
Field trials of different doses of 30% Qingjinxiu suspension concentrate against corn field weeds were conducted. The results showed that excellent weed control performance was achieved when 30% Qingjinxiu suspension concentrate was applied at the 2～4 leaf stage of corn and within the application dosage of 0.99～2.70 kg/hm~2. The average control effect against barnyardgrass was 43.0%～98.8%, and 83.2%～100% against all kinds of broadleaf weeds. Its inhibition effect to weed fresh weight was 60.0%～98.8%.30% Qingjinxiu SC is a herbicide of a broad spectrum and a persistent effect. No negative effect on corn growth and corn yield was found.
