Your options are to either dig it out, or to cut it off and then apply a strong solution of a weed killer with either glyphosate or triclopyr as the active ingredient to the resprouts or you can cut them off and paint these products full strength on the cut surfaces. You can also mix according to label instructions and apply these products to the foliage but if they get on desirable plants those plants will be killed too.
Thanks for the question. Please stop in again soon!
