Thank you so much. Great detailed explanation.

Could you advise me on the amounts of Water, Diquat, Cutrine plus and surfactant in my 15 gal sprayer. I want to use all the solution in the sprayer to treat 1/2 of pond at a time.

I get a little confused about ratios. I have, in the past, just used the ratios on label, filled up the tank but just spray treated pond not really figuring the area. My concern has always been that I am not getting enough chemical into the pond or too much.
Ideally the ratios I put in sprayer would allow me to use all of the solution per 1/2 area.

Hope you understand.

So sorry if asking silly question. I am a woman and we tend to over think everything. LOL

Thank you again for any help.
