| Abstract: | 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 1500-2250 g/hm2 and sprayed with water of 750 L/hm2.The optimal use time was pre-emergence after sowing. |
