管理信息
预防措施：金合欢(Acacia farnesiana) 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14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世界其它地区。物理方法：经由农耕或挖掘除根而摧毁“(斯瓦布里克, 1997。PIER, 2002)。虽然地面上的部分可能会死于林火，但是很快就会从地下基部再生芽“”(史密斯, 1985)。一旦建立族群，幼苗生长迅速，受损或摘除顶端后，很快重新发芽。金合欢(Acacia farnesiana)的新芽可以在5个月后长到接近原株高度的一半 (鲍威尔等人, 1972)。因此，使用机械割掉顶部结果只能短期抑制金合欢(马茨等人, 1978)，对于相关的生长速度较慢的木本植物具有竞争优势。几乎单一种，浓密的金合欢可能在使用扰乱土壤的控制方法后两到三个生长季节后发展出来。 化学方法：可能容易使用除草剂清除，包括毒莠定，甲基metsulfuorn，草甘膦和氯草定，也可以在叶上或刚切除的树干上施用2,4-D，或在残留的树桩上注射。
此外也可能容易残留除草剂，包括丁唑隆除草剂和环?酮(斯瓦布里克, 1997年 PIER, 2002)。在叶面施用1磅/英亩氯草定有效，也可以用甲磺隆0.45盎司/英亩或在基部树皮施用 2,4-D或氯草定2%的柴油溶液。在毛伊岛试验雨中施用于叶片和树皮，被认为是无效的，但这些试验被一个严重的旱灾干扰“(Motooka等人, 2002年。PIER, 2002)。   
地点特有的管理信息Ascension Is.
The Management Plan suggests this species may become as harmful as Prosopis, with which it shares many similarities. It recommends mapping the distribution of this species as well as assessing its invasive potential and control methods (Pickup, 1999 in Varnham, 2006). Marquesas Islands
Legally declared a threat to biodiversity in French Polynesia (Meyer 1998). Meyer (2000) lists this species as a dominant invader of dry sites. Queensland
The best time for treatment is during autumn when plants are actively growing and soil moisture is good. Basal bark spray: For stems up to 15 cm diameter, carefully spray completely around base of plant to a height of 30 cm above ground level. Thoroughly spray into all crevices. Larger trees may be controlled by spraying to a greater height, up to 100 cm above ground level. At any time of year, cut stems off horizontally as close to the ground as possible. Immediately (within 15 seconds) swab cut surface with herbicide mixture.
