I mix the Cutrine liquid with an equal amount of water and use a 1 gallon pump sprayer. I apply it by spraying a stream a using a circular motion to disperse. The solid stream keeps it from blowing away like a fine mist would. It usually end up making two trips around my half acre pond to disperse 2 mixed gallons to get an uniform application. It's not messy and could easily be done from a boat as small as a kayak.
