Environmental and Economic Concerns

  • Displaces native plants, especially along shaded shorelines and in wooded wetlands
  • One of the most widely dispersed invasive aquatic plants in Florida’s public water bodies
    • present in about 55% of Florida public waters
  • Shoreline populations break loose, forming floating islands
    • block access
    • cover native plant habitat
  • Roots in new areas, spreading the infestation

Management Options

  • Biological: None available
  • Chemical: Imazamox, 2,4-D + diquat + Kinetic, glyphosate
  • Mechanical: Harvest floating mats; roots fragment into new plant
  • Physical: Hand pulling; use caution due to oxalic acid irritant in plant. Need to remove entire rhizome or plant will regrow.
