In order to analyze the control efficiency of butralin + acetochlor 50% EC to weeds, and the safety to soybean in soybean fields, the experiments were done by soil spray after sowing, pre-emergence and regular investigation. The results showed that butralin+acetochlor 50%EC could effectively control annual grass weeds and most broadleaf weeds. The efficiencies were 77.0%-96.3% on the 20th day after spraying, and 79.5%-97.0% on the 40th day after spraying. It was safe to soybean. The application dose of active ingredients were 1 500-2 250 g/hm2 and sprayed with water of 750 L/hm2. The optimal use time was pre-emergence after sowing.
