Answers:    Rodeo, the glyphosate for wetlands works well, but application is tricky. Timing is critical. Also river needs to be fresh, not pond hose down and you probably need a surfactant mixed surrounded by as well.

Remember glyphosate take time!! It's not an immediate murder tho you should see something before 10 days.
