Coontail Control

In lakes, we recommend using our Dock and Swim Area Products for coontail control. The products contained in the package will eliminate the current coontail growth as well as reduce the nutrients in the water required for future re-growth. Dock and Swim Area Products include Dibrox® Herbicide a contact herbicide that will kill any plants it comes into contact with. Also, Hydrothol Granular and Navigate are both effective aquatic herbicides that are known to take care of Coontail problems.

In ponds, also using Dibrox® Herbicide  is an effective solution for coontail. Check out our Pond Solution products.

Identifying Coontail 

(Ceratophyllum demersum)

Coontail has a number of physical characteristics that will allow you to identify it. The plant actually lacks true roots, though it may be loosely anchored to the sediment by pale modified leaves. The central stem of the plant is hollow. The plant's dark green leaves are 1-3 cm long and are spiny and forked. Upper leaves may reach the surface of the water. The leaves are arranged in whorls (5-12 at a node). Whorls are more closely spaced near the end of the branches. Flowers are tiny and hidden in the axils of the leaves. The plant may be long and sparse, but is often bushy near the tip (with an appearance like a racoon's tail, this is how the plant received its name).

Habitat Preference: Coontail grows underwater with no true roots (and can drift between depth zones). Coontail can grow in clear to murky water because it has a tolerance for low-light conditions. The plant can be found in depths of up to 20 ft.

How does Coontail differ from other species? Leaves of coontail are usually forked twice. The leaves are also distinctly spiny. Look for the bushy tip (raccoon tail-like appearance).
