Herbicide Control:

We have a possible option for how to kill turtleweed that may offer control.

1. Cattail and Water Lily Control (Imox + surfactant) (for ponds or lakes) – liquids that are mixed and diluted with water and sprayed directly on the plants.

Treatment Tips:

When treating turtleweed,

• 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.
• Turtleweed is not listed on the Imox label, but it is a broad spectrum herbicide and will control a wide variety of weeds.
