While I have used a few different implement, ATV and back sprayers...I am wondering if anyone has tried a backpack fogger for trail maintenance. Jim Ward is where the idea came from (and it sounds like he mounts his on an ATV and runs a much higher percentage of herbicide than recommended to add even more to it). I am just not sure why this would be better or different....it keeps taking me back to the aerial applications. My personal goal beyond curiosity would be to keep trails open and limit encroachment of the adjacent plants-shrubs-trees.
