    预防措施:将入侵移除后,种植本地物种将有助于阻碍重新羽绒草建立族群。监测其幼苗并加以清除是一个很好的做法,因为幼苗很容易拔除。
    羽绒草(Pennisetum setaceum)的风险评估,由Kaulunani 都市森林计划与美国森林服务部赞助,Dr. Curtis Daehler (UH Botany)执行,针对夏威夷与其它太平洋岛屿。外来植物检查系统源于Pheloung 等(1999) 小幅修正后,使用在太平洋岛屿。其结果是26分,建议如下:可能对夏威夷和其它太平洋群岛造成重大生态和经济损害,WRA 分数很高,这是依据已出版的描述物种生物学和行为学的数据在夏威夷或其它地方的世界。

    物理方法:根据Benton (1998),其种子寿命很长,使其很难控制。小型侵袭可用手连根拔起,消灭花序,以为防止种子扩散。用手拔除可能需要每年重复几次。咨询服务中心(2002)建议,消灭种子头以减缓其蔓延。由于它每年结实数次,必须提高警觉。唯一防止将来种子生产,减少野火威胁的办法是,消除所有的羽绒草(Pennisetum setaceum),用手拔除或用铲子、撬子挖除。移除整个植株可消除夹在植株基部叶片的种子。

    化学方法:广泛侵袭最好使用除草剂控制,特别是那些有系统性活动的地方。 English  français

            摘要: A study on the use of a screening system to assess proposed plant introductions to Hawaii or other Pacific Islands and to identify high-risk species used in horticulture and forestry which would greatly reduce future pest-plant problems and allow entry of most nonpests.
