I have a Chapin sprayer that sits on the back of a sxs to spray small food plots, lawns and fence rows, in-other-words, not a commercial grade sprayer like it sounds you will be needing, but it has a side tank for injecting the chemical at whatever predetermined concentration you desire, I really like it as you only use what you need, and the rest of the chemical can be put up for later use, no more mixing a tank full of stuff and only using half of it, I love it for that, and the chemical does not go thru the pump, it is only pushing clean water, other then most of the time a add my spray additive to the water. Good Luck!
