Manual/ Mechanical Control:
Physically raking elodea plants and pulling the roots can be an effective way to manage this plant, but it can re-grow from any remaining fragments or roots.
There are multiple options for controlling elodea:
- Dibrox – liquid that is diluted with water and sprayed over the plants, fast-acting
- Spritflo (for ponds with no outflow) – liquid that is poured into the water and spreads throughout the entire body of water, offers extended control
- Flumigard – granules that are dissolved in water and sprayed (early morning is best) over the plants, fast-acting
