I live in missouri, and right now i am studying for my pesticide applicator test. While reading my manuals a few questions came to my head when i came across "restricted pesticides" I want to add fertilizer programs to my lawn care business that include weed and feed applications that will rid my yards of annoying dandelions and other common weeds. I read many times here on lawnsite that i would have to get certified to apply any type of pesticide including minor items such as round-up. According to my reading only items that have "restricted use" on the label require a license. So do i really have to get a license to apply weed and feed to my lawns. Or do different rules apply to commercial applicators?
