Manual/ Mechanical Control:
Physically pulling hydrilla and digging up the roots can be an effective method of control. Hydrilla will re-grow from any fragments, roots, or tubers remaining in the water.
- Spritflo (for ponds with no outflow) – liquid that is poured into the water and spreads throughout the entire body of water, offers extended control. Spritflo will give the best control.
- Dibrox + Mizzen (for ponds or lakes) – liquids that are diluted with water and sprayed over the plants, fast-acting
- Hydrothol (for lakes) – granules that are broadcast over the plants
