Go to your local NRCS office and enroll your property into one of the programs that will provide cost share dollars to help remove it. I have my ground in EQIP and WHIP. Both programs provide cost share money (WHIP is a 75% cost share) to pay someone to kill it. One is Federal and one is State funded. They will not overlap. I can't explain why I am in both. It just worked out that way. They are great programs though. You can make out of them what you wish to accomplish with you property.
I hate the stuff and anyone trying to start it should not do it. Talk to a local biologist and plant something native to your area.
