Maybe try cutting it back very severely and then heavilly mulching with cardboard and then sawdust or some such to hold the cardboard in place, from the base of whatever plants you are leaving to at least a foot past the remaining stubs. Or cut it way back and turn pigs in there and see if they will root out the roots for you.
I think, and if I'm wrong someone will be quick to point it out that if you keep any green plant from light and water long enough it will soon start to struggle. (Seeds are a different story).

I remove these rose bushes all the time. I usually take a front end loader and smash the bushes down so I can get to the base of the bush. Then I put the bucket lip angled down slightly and positioned right at the base and drive forward. Once it starts to come out of the ground you might have to back up and get the lip of the bucket under the roots. This rips the majority of the roots out and if your careful can be a lot less messy than digging them out with a shovel. I lop all the branches off at the base and shake the dirt off the roots. Move onto the next bush. You can also wrap a chain around them and pull them out.
Good idea Galen.
Never thought about that! Don't know why, as last summer I pulled out a 6 foot manitoba maple that kept trying to grow under the house with some rope wrapped around the stem and tied to the trailer hitch on the truck. If it'll work on those things then it should certainly take out roses, if they are too big to pull by hand.
