Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Whitecap didn't work?

Quick question.

I treated a .25 acre 4ft average depth pond with 8oz. Whitecap about 45 days ago.

It was getting a pretty good stand of coontail and bushy pondweed.

If I figured right, I hit it with a 90ppb ratio...

The coontail is pretty much gone but the bushy pondweed all but went away except for a stand about 20 yards long, right along the south side of the pond. It sunk down below the surface and I thought it was going to die but now its blowing up again. Its probably doubled in size, at the surface, and growing everyday now it seems. At the rate its going it will surround the pond again in probably 2wks.

I premixed the whitcap in 10 gallons of water and threw it in. Also, no runoff since...

What gives... This is the first time I used whitecap before.

Please don't tell me that! I'm making payments on $400.00 of the stuff!

Yeah, I just want to know what to expect, and to check my dosage rate to make sure it was correct.

Anyone have input here.

I hope someone comes a long with your answers. I wish I could help.

Here is the lable.

Yeah i checked my numbers again and I hit it atleast with 90ppb. Only thing I read is it says 30-90 days for maximum results. Well its been 45 and Im seeing the pondweed growing like crazy... Don't see that in the label anywhere
