Control Hydrilla

Many people ask how to get rid of Hydrilla. The following options can be considered for how to control Hydrilla.

 

Manual/Mechanical Control:

If you are considering how to remove Hydrilla, physically pulling this plant and digging up the roots can be a somewhat effective method of control. However, physical control can be difficult. Hydrilla can re-grow from any fragments, roots, or tubers remaining in the water.

 

Herbicide Control:

There are multiple options for how to kill Hydrilla that offer great or some control.

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

 

When treating Hydrilla,

  • Spritflo can be used at the first signs of growth.
  • With other herbicides, treat when the plants are established and actively growing.
