Physically pulling Fanwort plants and digging up the roots can be an effective method of control. Fanwort will re-grow from any remaining seeds or fragments left in the water.
There are a few options for controlling Fanwort:
- Spritflo (for ponds with no outflow) – liquid that is poured into the water and spreads throughout the entire body of water, offers extended control.
- Dibrox (for ponds and lakes) – liquid that is diluted with water and sprayed over the plants, fast-acting. Dibrox will offer some control.
- Flumigard (for ponds and lakes) – granules that are dissolved in water and sprayed (early morning is best) over the plants, fast-acting. Flumigard will offer some control.
