Rayb it is 1-2 gals/ weeded acre. In general we have our system down and mix in 4-6 ozs/gal and with a good mist hitting target plant will smoke it. However where Shawn is located water quality is diff and he sems to have to use more, this is for sure the case with copper products.

MY advice is to look at label for plant you are treating for instance for hydrilla we have to use 2 gal/acre rate. Other native plants will kill over with much less. Once you know the rate then figure your surface area. I would dilute it more than you think so you do not run out like Shawn said. You can always walk around again quickly if you have some left. make sense?
