| 中文摘要: |
| 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30 d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。 |
| 英文摘要: |
| 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. |
