摘　　要：[目的]刺萼龙葵是外来有毒有害杂草,筛选高效防控药剂对控制其危害蔓延具有重要意义。[方法]采用室内生测法研究了10种茎叶处理除草剂对刺萼龙葵的防效及对植株生物量的影响。[结果]结果表明:百草枯和草甘膦对刺萼龙葵的防效最佳,施药后第5天百草枯的效果达100%,而草甘膦药后15 d可达到相同的防效。氯氟吡氧乙酸、草铵膦和2,4-滴丁酯药后30 d对刺萼龙葵也具有较好的防效(≥85%),对植株生物量的抑制效果均在90%以上。[结论]百草枯、草甘膦、草铵膦、氯氟吡氧乙酸和2,4-滴丁酯可作为应急防控刺萼龙葵的候选除草剂。Buffalobur（Solanum rostratum）is an exotic noxious weed and it is most important to screenhigh effective herbicides to control its spread and infestation.[Methods]Greenhouse studies were conducted toevaluate the control efficacy and biomass inhibition of 10 foliar-applied herbicides to buffalobur.[Results]Resultsshowed that paraquat and glyphosate have better control effects on buffalobur,the efficacy of paraquat reached100%at 5 days after treatment（DAT）,while glyphosate achieved the same efficacy at 15 DAT.Fluroxypyr,glufosinate and 2,4-D butylate also have good efficacy（≥85%）on buffalobur and the biomass inhibition were allmore than 90%at 30 DAT.[Conclusions]Paraquat,glyphosate,fluroxypyr,glufosinate and 2,4-D butylate arehopeful candidate herbicides for emergency control of buffalobur.
