管理資訊
預防措施:粉綠狐尾藻(Myriophyllum aquaticum)的風險評估,由澳大利亞太平洋島嶼生態系統風險評估計畫執行(PIER),使用澳大利亞風險評估標準(Pheloung, 1995)。其結果是20分,建議如下:應禁止進口此植物(澳大利亞)或此植物可能是有害的(太平洋)。物理方法:由於此植物行無性繁殖,使用機械切斷根莖和莖只會增加其蔓延。 化學方法:華盛頓州生態部(2003)報告說:雖然有人認為粉綠狐尾藻(Myriophyllum aquaticum)對除草劑很敏感,很難對它達成完全的控制。其水面上的莖,葉有厚的蠟質角質層,需要用一個潤濕劑,讓除草劑滲透入這個角質層。通常噴灑除草劑會使水面上莖葉倒入水中,在除草劑透入植株以前,除草劑會被水洗掉。 生物方法:南非已經有效地使用生物控制方法,正在使用一種Lysathia屬的昆蟲(Mabulu, L.Y.,pers。comm., 2004)。此植物單寧含量較高,所以大多數食草動物,包括草魚,都不喜歡吃它(華盛頓州的生態系, 2003)。

Science for Conservation 185. 30 p. 摘要: This report is the second stage in the development of a Border Control Programme for aquatic plants that have the potential to become ecological weeds in New Zealand. Importers and traders in aquatic plants were surveyed to identify the plant species known or likely to be present in New Zealand. The Aquatic Plant Weed Risk Assessment Model was used to help assess the level of risk posed by these species. The report presents evidence of the various entry pathways and considers the impact that new invasive aquatic weed species may have on vulnerable native aquatic species and communities.
