I recently purchased a solo 425 backpack sprayer for $79. I have an old one that I have used for more than 5 years.
I have used a spreader sticker for years and it really helps when you need residual coverage. I use ThermX370 (yucca extract). It only takes a few drops per gallon. Some of the stickers will generate quite a bit of foam. I make sure not to add more than the directions indicate.
