Horseball. Welcome to the site.

I am not the expert that I am sure will come up with better answers very soon. I do know there is a chemical which you can spray on the locust stumps right after you cut them down. It goes a long way toward keeping them from sprouting. I don't know the name of that particular herbicide, but I bet someone here does. I hired a couple of guys to cut some of my black locusts a few years ago and it did a great job.
