    预防措施:QDNRM(2005)报告说:新建立的植群应在开花结果之前予以摧毁。鸟类食其浆果,将种子散播到新的地方。不要把此植物种在花园,因为这将会是一个潜在的传播据点。路边的侵袭应进行控制。同样的建议,适用于种植区,先控制过度放牧的地区,限制此植物的竞争力,应定期检查新的侵袭。

    柳叶夜香木(Cestrum parqui)的风险评估,由澳大利亚太平洋岛屿生态系统风险计划执行(PIER),使用澳大利亚风险评估标准(Pheloung, 1995)。其结果是11分,建议如下:应禁止进口此植物(澳大利亚)或此物种可能具有高风险(太平洋)。

    机械方法:克罗夫特和Holding(2004)报告说:机械控制法是用手挖除植物,包括移除所有的根。由于它能从根部碎片吸根再生,后续控制往往是必需的。使用覆盖以抑制幼苗生长已被使用。这种方法可保持土壤水分,并提供原生植物保护。覆盖法常在化学或机械控制法之后使用。

    化学方法:克罗夫特和Holding(2004)报告说:喷洒除草剂的化学控制法,用于大型侵袭,攻击成熟的植群。个别的植株可在基部树皮用滴管瓶注入除草剂。处理时机是重要的,应该在结实之前实施。可能需要后续处理以抑芽和幼苗生长。

    QDNRM(2005)列出了多种化学物质及各种不同的方式来控制柳叶夜香木(Cestrum parqui)。毒莠定和绿草萣(Grazon DSR)可以应用于晚春到初秋,并彻底覆盖所有的叶和茎。当柳叶夜香木生长非常活跃时,可用三氯氧乙酸(Garlon 600R)彻底喷洒叶片。Amitrole(Amitrole TR)可用于开花前夕,如有必要,可重复施用,直至达到足够的控制效果。2,4-D的和毒莠定(毒莠定 75~DR)的可用于处理小区域。最后,毒莠定和绿草萣,AccessR可以作为一个基部树皮或削砍残端应用(QDNRM, 2005)。

    生物方法:QDNRM(2005)报告说:柳叶夜香木(Cestrum parqui)树苗可以经由其它植物的激烈竞争抑制。先控制植物成株,然后种植积牧草或本地原生树种,与其幼苗竞争。这种方法不太适用于河岸和砾石床。把植物完全挖出来,可以杀死它。必须小心移除所有黄色的根,否则会再生。最好是把根烧掉。 English

    Bega Valley
    C. parqui is declared noxious in Bega Valley, Eurobodalla and the Shoalhaven, meaning that it must be fully and continuously suppressed and destroyed (Eurobodalla Shire Council, 2004).
    Eurobodalla Shire Council (2004) explains that “Seedlings may be hand pulled or dug out. Cut and paint or stem inject mature plants, preferably before they begin to develop seed. To improve the effectiveness when using the cut and paint method, peel the bark back all around the stump and apply herbicide quickly to both the cut face and the exposed outer wood. Spray with selective herbicides. Follow-up treatment will be needed on seedlings”.

    New South Wales
    In Queensland, New South Wales, and Victoria, C. parqui is a declared noxious weed due to its ability to invade agricultural land, and its known toxicity to livestock (Croft and Holding, 2004).
    “In the New South Wales communities of Bundeena and Maianbar, Community involvement programs have been highly successful on public land, and on the properties of cooperative landowners who have removed all plants with the help of council. The joint efforts of the community and the council proved to be a great approach, especially for a weed that was found in many home gardens. The nature of the area, however, is a high proportion of ‘weekender’ properties, which are rarely occupied. These present a long-term challenge to the program.
    The group is hoping that several highly visible and successful spray events by council, and continued local media releases will improve the likelihood of compliance on private property, which is now where a majority of infestations can be found.
    Community support for the program has meant that to date the noxious weeds legislation has not been enacted. It is anticipated, however, that in order to complete the planned eradication of cestrum from the area some landowners will eventually have to be pressured.
    Council has now developed a fully integrated management plan for green cestrum. It involves mobilising interested members of the community to participate, liaison with other authorities (especially the NPWS) and using a variety of control methods. As the program progresses it will be measured against outcomes and adapted as required to achieve the stated goals” (Croft and Holding, 2004).
    New Zealand
    C. parqui is included in the First Schedule of the National Pest Plant Accord. All plants on the list are designated as Unwanted Organisms, and are banned from sale, propagation and distribution throughout New Zealand. Please see National Pest Plant Accord for the complete list.
