I don't think the version of Invasive Morning Glory that I have is the one others call Bindweed, but their characteristics are similar. I don't recommend rototilling as that breaks up the roots and every 1" piece of root has the potential to grow a whole new plant!

I've done heavy mulching with paper and wood chips. It doesn't stop it, but it encourages it to run along just under the paper, so when you go to check, you can pick up long runners, then reapply and it has made it work that much harder.
It's persistent. I tried a heavy straw mulch. It loved mulch! I think it's due to the additional moisture that mulch leaves in the soil.

In the ground I found keeping on top of it prevents it from ruining other plants, but I haven't really eradicated it from any place yet.
