經濟有效控制黃鳶尾(Iris pseudacorus)成功的關鍵是為了防止新的傳播或在族群尚小易於管理時開始控制工作。使用早期干擾控制,成功的可能性很高。一種綜合的辦法,密切監測任何重新生長的種子或重新發芽或任何新的恢復種群,似乎是一個最有效的方法可獲得最佳結果(Tu, 2003)。機械方法:Tu(2003)報告說:使用人工或機械方法移除整個黃鳶尾(Iris pseudacorus)根莖塊能成功地控制小型,孤立的小塊植群。然而這些方法非常耗費時間和勞動,因為即使是很小的根莖碎片都可會重新發芽。此外,挖掘會擾亂土壤,使根莖破碎,反而會促進黃鳶尾(Iris pseudacorus)及種子庫中其他不良的種子發芽(Jacono 2001,Tu 2003)。拔除或砍筏黃鳶尾(Iris pseudacorus)可以提供足夠的控制,但必須重複好幾次,每年削弱它,最終殺死此植物。每年去除花朵或果實可以防止植物種子發育和種子的傳播,但不會殺死這些植物(克勞福德 2000,Tu 2003)。拉米(2001)報告說:一旦感染區廣泛的根莖已經大量增生,使用機器與火燒可能是唯一可行的方法。 化學方法:Tu(2003)報告說:黃鳶尾(Iris pseudacorus)可以用除草劑有效地控制。由於它通常生長在水中或靠近水的地方,必須用水草除草劑和助劑。草甘膦(例如 RodeoR,AquamasterR或GlyproR)25% 的溶液(13% a.i.)使用流滴噴頭施用,或使用 5至8% 的溶液噴灑,如果用適當的非離子型表面活性劑輔助處理,能有效地殺死黃鳶尾(Iris pseudacorus)(河麥克萊恩,pers。通訊)。使用時機和選擇的技術將決定防治效果,並應盡量減少對非目標物種的影響。可以直接在葉片施用除草劑,或在剪切葉和莖之後立即在剪切面施用除草劑,可直接施用於葉片或剪切後的莖部,可用流滴芯系統或使用背負式噴霧器。務必要全程採取適當的預防措施和適當的衣物及設備,並遵守除草劑標籤上所有的指示。使用染料與除草劑混合,可幫助你留意偶然接觸或洩漏的除草劑。拉米(2001)報告說:黃鳶尾(Iris pseudacorus)很容易受到許多已登記除草劑影響,但可耐受terbutryne。

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.
