Hello,
A broadleaf herbicide that contains any combination of the active ingredients 2,4-D, dicamba, triclopyr, clopyralid. Quinclorac alone will provide good control as well.

We have tried 24d and it doesnt touch it.. turns yellow  for a few days then comes back green.. most of these plants are 3-4 feet tall

Hello,
Yes, which is why I recommended it in combination with other herbicides such as dicamba, triclopyr, clopyralid, or quinclorac. There are many product options with some combination of 2 or 3 of the herbicides mentioned above.
