| 中文摘要: |
| 化学防治是一种对恶性入侵杂草豚草有效的防治措施，可在IPM中作为应急手段。为筛选出对豚草具高效的除草剂品种，采用茎叶喷雾法，在田间测定了草甘膦、百草枯、氟磺胺草醚、乳氟禾草灵、氯氟吡氧乙酸、双氟磺草胺·唑嘧磺草胺6种除草剂对豚草的防治效果。结果表明，无论是苗期(株高30 cm)还是成株期(株高60 cm)，除双氟磺草胺·唑嘧磺草胺，参试除草剂均对豚草表现出良好的防治效果。可见，草甘膦、百草枯、氟磺胺草醚、乳氟禾草灵、氯氟吡氧乙酸均可应用于防治野外发生的豚草。 |
| 英文摘要: |
| Common ragweed,〖WTBX〗 Ambrosia artemisiifolia 〖WTBZ〗Linn., is one of the worst invasive weeds. Chemical control is an effective measure that can be chosen as an emergency approach in IPM. In order to select highly effective herbicides, effects of six herbicides (glyphosate isopropylammonium, paraquat, fomesafen, lactofen, fluroxypyr and florasulam+flumetsulam) on common ragweed were evaluated by foliar spraying in the field. The results showed that with exception of florasulam+flumetsulam, other tested herbicides showed good control efficiencies on common ragweed at both seedling (30 cm in height) and mature (60 cm in height) stages. Based on this experiment, we suggest that glyphosate-isopropylammonium, paraquat, fomesafen, lactofen and fluroxypyr can be used for controlling common ragweed in non arable land. |
