If you got a way to haul it. Tank sprayer is the way to go.
Northern Tool has sone good ones. 10. 15. Gal.
Co-op / feed store will also.
If you have much to spray, 1 gal at a time is a pain.
If you go that route, power it with a separate deep cycle battery.
Axe me how i know.
For a large area, I have a 20 gal tow behind that I pull with my garden tractor. It also has booms for broadcast spraying on lawns or pastures.
