2. Cattail and Water Lily Control (Imox + surfactant) (for ponds or lakes) – liquids that are mixed and diluted with water and sprayed over the plants.
3. Liquid 2, 4-D (for ponds or lakes) – liquid that is diluted with water and sprayed over the plants. Most effective on treatment areas larger than a half acre, this allows longer contact exposure time.

Treatment Tips:

When treating American featherfoil,

• With Imox or other systemic herbicides, treatment is most effective when the plants are mature or close to full grown. This allows for more plant surface to spray enough mixture on.
  • Treat in late summer to early fall to get better kill of the root systems. At this time, plants are pulling energy into their roots to store for the winter.
• With Dibrox or 2, 4-D, treat when the plants are established and actively growing.
