Manual/Mechanical Control:

If you are considering how to remove Elodea, physically raking this plant and digging up the roots can be a somewhat effective method of control. However, physical control can be difficult. Elodea can re-grow from any roots or fragments remaining in the water.

Herbicide Control:

There are multiple options for how to kill Elodea that offer great control.

1. Dibrox (for ponds or lakes) – liquid that is diluted with water and sprayed over the plants, fast acting.
2. Spritflo (for ponds with no outflow) – liquid that is poured and spreads throughout the entire body of water, offers extended control.
3. Semera or Flumigard + surfactant (for ponds or lakes) – granules that are dissolved and mixed or liquids that are mixed and diluted with water and sprayed over the plants (early morning is best), fast acting.

Treatment Tips:

When treating Elodea,

• Treat when the plants are established and actively growing.
• Spritflo can be used at the first signs of growth.
