We have a bit of an FA issue in 2 of our 3 ponds and a little sago pondweed and coontail in another. The treatment usually is copper sulfate early in the year and a Cutrine Plus/diquat combo after mid-June.

Will those chemicals kill hardy water lilies? CS is pretty selective on the FA but I am not sure about the other stuff with these nice lilies.

Anyone have advice on that? Can they survive these herbicides? Thanks. BM61
