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.
- Semera or Flumigard (with Surfactant) – granules that are dissolved or liquid that is diluted 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.
