What about flowthrough? Does that impact the effectiveness of Sonar? What kills watermeal? What kills alligatorweed?

Since cockandlock won't come back out and play, knock yourself out. I know you have all the good stuff to kill both watermeal and alligator weed.

Imazapyr, 2,4-D, and triclopyr work the best on alligatorweed. Waterflow does affect fluridone effectiveness on duckweed. How much, I'm not sure. You would have to ask someone who knows more about fluridone.

wouldn't releasing a couple alligators into the alligator weed knock it down? they do eat it, right? I mean, if a gadwall will eat it, I know an alligator will.
