摘　　要：为了验证10%苯嘧磺草胺悬浮剂防除冬小麦(Triticum aestivum L.)田阔叶杂草的田间药效及安全性,采用茎叶喷雾法进行田间药效试验。结果表明,药后20 d,10%苯嘧磺草胺悬浮剂30.0、52.5、75.0、105.0 g/hm2对繁缕[Malachium aquaticum(L.)Moench]、猪殃殃[Galium spurium L.]、婆婆纳[Veronica didyma Tenore]等杂草的综合防效为89.20%~100.00%;药后40 d,株防效为88.60%~100.00%,鲜重防效为89.10%~100.00%。同等用量下该药剂对猪殃殃的防除效果优于婆婆纳和繁缕。田间拟推荐剂量为30.0~75.0 g/hm;。供试药剂在拟推荐剂量内使用可有效防除冬小麦田阔叶杂草,且对冬小麦安全。In order to verify the field efficacy and safety of 10%saflufenacil suspension agent(SC)in controlling broadleaf weeds in winter wheat(Triticum aestivum L.)fields,field pharmacodynamic experiments were carried out by the stem and leaf spray methods.The results showed that 20 days after the administration,the dosage of the 10%saflufenacil SC in the field were 30.0,52.5,75.0,105.00 g/hm2,the weeds control effects on quantity were 89.20%~100.00%on Malachium aquaticum(L.)Moench,Galium spurium L.and Veronica didyma Tenore.40 days after the administration,the weeds control effects were 88.60%~100.00%,and the fresh weight control effects were 89.10%~100.00%.Under the same dosage,the agent had better control effect on Galium spurium L.than Malachium aquaticum(L.)Moench and Veronica didyma Tenore.The recommended dosage of 10%saflufenacil suspension agent SC in field were 30.0~75.0 g/hm2.Within the range of recommended dose,10%saflufenacil SC could effectively control broadleaf weed in winter wheat field,and it was safety to winter wheat.
