Michigan has tightened up on the use of ag grade herbicides and pesticides, you have to have an applicators license (which I have). I tend to use Glyphosate or 24D (B) on my hay fields and Roundup Ultra Max for general invasive weed control and both require an applicators license here now. The stuff you can buy in box stores is really marginal at best. Nice thing about 24D (B) which is buffered 24D is it's a selective killer and won't harm (to a great extent) alfalfa, whether Vernal or Hybrid (roundup tolerant). I prefer Vernal myself because the hybrid alfalfa is hard to control and because it's a tuber root and spreads via underground roots, it always want to grow outside a hayfield, whereas Verrnal can be controlled via application of a systemic herbicide.
Do I think requiring an applicators license is a good thing? I don't. One it costs money which the state gets and wastes and two, if people bothered to read the instructions and MSDS labelling that is on every container (by Federal Law),that is enough.
Problem is today, no one bothers to read anything and that includes tractor owners manuals. In fact a huge amount of posts on here where owners ask dumb questions can be answered by just reading the owners manual and following it. Like my wife says, 'it's a concept thing'
