Haven't had to deal with watermeal in our area lately, but Clipper is labeled for watermeal. It is our go to choice now for duckweed, it will flat scorch duckweed even in higher pH waters. A little more expensive than diquat/copper combo but one application does it. Kelly may have some thoughts on this.
