| 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30d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.

| Abstract: | 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.... |
