I have a posted reply in the ID plants forum but I figured I was asking the question in the wrong forum so I appologize.

Anyway, I have a problem with American Pondweed. The plant was anywhere from 10-60 feet out along the entire shoreline of my 8+ acre pond.

I have been treating it with Weedtrine. This seems to be working but up till today I thought the plant was Water Shield. After I mentioned this, I was told that weedtrine wasn't actually doing much of anything and I should maybe try Renovate.

After researching and coming to the conclusion that this isn't water shield, now I wonder if that same advice still applies?

It certainly seems to be killing and sinking this plant but I'd like to know what's happening since this stuff is somewhat expensive.

On the Missouri dept. of conservation's website they call the plant diquat what does this mean in relation to the herbicide? Just wondering because that same term was used when talking about weedtrine.
