Control Illinois Pondweed

Manual/ Mechanical Control:

Physically pulling Illinois pondweed and digging up the roots can be an effective method of control. Illinois pondweed will re-grow from roots or seeds remaining in the water.

Herbicide Control:

1. Spritflo (for ponds with no outflow) – liquid that is poured into the water and spreads throughout the entire body of water, offers extended control
2. Hydrothol (for lakes) – granules that are broadcast over the plants
3. Dibrox (for ponds or lakes) – liquid that is diluted with water and sprayed over the plants, fast-acting. Dibrox will offer some control.
