it's reported that they can become active again after being dormant for 70 years,

it's a little early to spray yet a couple of more weeks would give better kill weather permitting
Don't cut it

We have a large stand of this! Very large.

Going it hit as much of it as I can with Round up in a few weeks.

what do you do with the bits that die off? Just leave them? Or cut them and leave them? Or cut and take and burn?
