I want to apply barricade for poa control and I need to be precise as we will be overseeding winter rye about 8 weeks after the application. I can't be "doing my best" with a back pack. The coverage needs to be precise and uniform. I would love to buy one of the ride on units with a boom but I just don't do enough to justify the cost. Anyone used one of the booms that attach to a back pack? any thoughts. The areas I will be treating are 3-26K with most being in the 5-8k range.
