Hi-Yield Killzall Aquatic Herbicide is not labeled to kill or control waterlily therefore cannot be recommended. Hi-Yield 2, 4-D Selective Weed Killer is labeled for water lily. Please view the product label for more information. Also, take a moment to read over this article by Texas A&M on How to Control Water Lily for additional information and treatment methods.
