摘  要:
为验证50%仲灵.乙草胺乳油对大豆田杂草的药效、杀草谱及对大豆生长的安全性,采用播后苗前土壤喷雾处理、定期调查的方法进行田间药效试验。结果表明,药剂50%仲灵.乙草胺乳油的杀草谱较广,对一年生禾本科杂草及大部分阔叶杂草有良好的防效。施药后20 d调查,对各种杂草株防效为77.0%~96.3%;施药后40 d调查,对各种杂草株防效为79.5%~97.0%。对大豆产量未见不良影响。50%仲灵.乙草胺乳油适宜有效成分用量为1500~2250 g/hm2,对水750L/hm2,播后苗前土壤喷雾。

摘  要:
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.
