Manual/ Mechanical Control:
Physically raking salvinia from the water can be an effective method of control. It will re-grow from any fragments that remain.
There are a few options to treat salvinia:
- Spritflo (for ponds with no outflow) – liquid that is poured into the pond and spreads throughout the entire body of water, offers extended control
- Flumigard (with surfactant) – granules that are dissolved in water and sprayed directly over the plants (early morning is best), fast-acting
- Cattail and Water Lily Control (Imox and surfactant) – liquids that are diluted with water and sprayed over the plants
