Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Cutrine Plus Mixing Question

I think I am going to spray the FA in my 2 ponds. It is not as bad as previous years but I am tired of looking at it. I have toyed with 3 options:

1. Do Nothing
2. Dye the water
3. Spray cutrine

I sprayed the pond about 3 to 4 years ago with good results. Someone gave me a rule of thumb mixing ratio and I wonder if any one can give that to me again. The label on the Cutrine is like a chemistry problem which I suck in.

1st pond is 2.16 acres with an average depth of 7-8 feet. Of course the FA is only in the 4' and less areas. the 2nd pond is about 3/4 acre with an average depth of 3'.

I am just looking for a mixture formula to knock some of it back. Suggestions are much apprciated.
