Can I use Crystal Blue Copper Sulfate to control cattails in retention pond?

How much to use in a 2 gallon pump sprayer?

Answer:

Crystal Blue Copper Sulfate is for algae only and would not affect cattails.  Diquat Water Weed and Landscape Herbicide would be a better option as it is an aquatic herbicide labeled for cattails
