Abstract: To screen out herbicides with high efficient and safe control effect on broadleaf weeds in flax field, spraying treatments after sowing before seedling emergence were completed by 6 mixed combinations of 5 herbicides. The results showed that: 42% atrazine SC 1500 mL/hm2 + 80% oxadiargyl WP 180 g/hm2 combination was safe for flax in recommended dose and the seedling emergence rate of flax was 53.01%, showing excellent control effect on broadleaf weeds in flax field. After 45 days, the control effect of plant and fresh weight was 97.96% and 98.4%, respectively. Thus, 42% atrazine SC 1500 mL/hm2 + 80% oxadiargyl WP 180 g/hm2 with water consumption of 900 kg/hm2 for soil surface spray treatment on the first day or the second day after sowing has good control effect and can be widely used in production.
