The County Agent may or may not be able to help. My county agent knows something about farm and range plants, gardens and cows. More than likely mine would send a sample to Texas A & M for identification. The result would probably be awhile in coming.
I think I would gather a sample of the watermeal, in a sealed plastic bag with water, and let an expert positively identify it. They can recommend chemicals to handle it.
I'm not very adept at identifying and treating water weeds but understand that things like watermeal and duckweed are tough to whip without repeated applications.
Anyone here have experience with tilapia eating or not eating that stuff?
