Control Marine Naiad

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


Manual/Mechanical Control:

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


Herbicide Control:

There are multiple options for how to kill marine naiad that offer great control.

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


When treating marine naiad,

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