Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Watermeal Spreading Quickly

Let's see if I can hit all your questions, PF.

I believe I have achieved an actual reduction because there appears to be substantially less WM now than when I began. Even though it's been stacked up the past couple of times out, it covers a much smaller area than it did previously and the layer is visually not as thick all over as it used to be when it stacked.

I have seen dead/dying watermeal the day after treatment (the last time with the heavier concentration was the first time I've been able to go back the very next day). It was turning various shades of brown and yellow.

My suspicion is that the higher concentration is what is really doing it as that was the first noticeable impact, but I think it would be crazy not to believe that there is some good cumulative effect happening here from what is now 3 treatments.

Spot treatment has not really been used at this point, so it's hard to say. Based on some observations of the last treatment, I'd guess it may work at high concentrations.

The nozzle is on mist and, as a result, I've definitely had some shoreline vegetation casualties, but I'm not too worried about that right now. I've been trying generally to be pretty careful with overspray going to undesirable places, but it can't be helped sometimes when misting. I have to say that the greatest single impact seems to have occurred when misting versus using a stream.

I'm looking forward now to perhaps getting another treatment in tomorrow as today just isn't going to work. I'll keep posting. And you are spot on, PF, that this is a morale builder for sure. It's been great to actually be able to go out and enjoy the look of the pond again and it encourages me to keep on it until the stuff disappears either from treatment or from cold, then to get an early start next year with chemicals and tilapia as early as I possibly can.
