摘　　要：采用茎叶喷雾法评价了7种防除阔叶杂草的除草剂对野外5～7叶期刺萼龙葵的防除效果。药后30d调查结果表明,7种除草剂对刺萼龙葵的生长均有一定的抑制作用,不同药剂对刺萼龙葵的防效差异显著。防除刺萼龙葵较好的药剂有48%三氯吡氧乙酸乳油、24%氨氯吡啶酸水剂和20%氯氟吡氧乙酸乳油,试验剂量下对刺萼龙葵的鲜重防效均在85%以上,25%氟磺胺草醚水剂对刺萼龙葵的防效较差。三氯吡氧乙酸、氨氯吡啶酸和氯氟吡氧乙酸能够有效防治刺萼龙葵,根据药剂的不同特性,探讨了在不同入侵地的应用可能性。Seven postemergent broadleaf herbicides were applied to evaluate their control efficacy against the buffalobur Solanum rostratum at 5-to 7-leaf stages.After 30 d treatment,the survey revealed that all of the 7 herbicides could inhibit the growth of buffalobur,and there were significant differences in efficacy among these herbicides.It was shown that 48% triclopyr EC,24% picloram AS and 20% fluroxypyr EC provided good control efficacy to buffalobur（85%）,while 25% fomesafen AS had weak control of buffalobur.Triclopyr,picloram and fluroxypyr could effectively prevent and control buffalobur,and the herbicides can be used in different invasion habitats in accordance with their herbicide performance.
