Is this elderberry?

We got busy with life and The Farm fields was growing up with bushes. We went to work with bush snippers and I bought a riding lawn mower so my Father could mow around the walls and keep the bushes at bay. Every thing tried to come back, the maple, oak, white birch, beech and sumac. All died with 2 years. My father said we grow it to death.    Except for that sumac. That stuff took years to die.

That sumac grows here in Kansas, if you spray the stuff in June with 2-4d, you can get rid of it.  Probably have to spray again next year.
