Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Coontail Control

A mixture of Cutrine Plus liquid to kill the algae along with Diquat will kill the coontail. Use the amount of Cutrine Plus that is listed on the label according to the amount of filamentous algae, and add to that anywhere from 1 qt to 2 qts of Diquat per acre foot of water to kill the coontail. The Cutrine Plus is needed to kill the algae on the coontail, then the Diquat will be able to be absorbed by the coontail re-treat as needed you can re-treat every 2 weeks until the coontail is under control.

Diquat dibromide is found in Reward and Tribune herbicides.

Try it at the rate that I noted above - it works.
