Todd, flouridone will kill the sago and other plants before it kills watermeal. Apply it all apply or slowly still will kill based on ppb level high enough to kill watermeal it will kill all vegetation. The grass carp due little good on watermeal. Tilpaia do well.
My sugestion in your case of saving the other veg is Diquat. It kills the heck outta of the watermeal, will you eradicate this year probably not. However when blown thick a mixture of water and 4-6 ozs Reward or similiar will kill the heck out of what it touches in a mist spray. Do this as needed to keep at bay. Next year hit again as it shows and combo with tilapia and might rid of.
summary- easier method pour in a few ounces of whitecap, but for your goals reward.
Great info, Greg! Thanks a ton for sharing those insights. I'm hoping the tilapia come through next year because I'd really prefer the natural approach for sure.
Let me make sure I am understanding your suggestion here. Basically, the fluoridone will kill all the other stuff but is less likely to touch the watermeal unless the chemical is in a really high concentration. Instead, Diquat is what will hit the watermeal more effectively. Is Diquat the brand name, or is that an active chemical ingredient? Someone, maybe DD1, suggested Diquat in another post, but I must have misunderstood the application was for watermeal and thought he was referencing FA instead.
As for mixing the Diquat, are you saying to do it in whatever the proper concentration is, then also add some Reward? If so, is that geared towards the watermeal, or will that also kill other vegetation?
As I mentioned, I do want to try to keep some of the vegetation in there, but I want that watermeal out in the worst way. If I have to sacrifice some other plants to achieve that goal, then so be it, but I'd love to save what I can and put some grass carp in there to work on those other things naturally.
Thanks for taking time to consider these questions, Greg. Again, I really appreciate the input.
