Yep, concentrated RoundUp works pretty good if you essentially ring bark the tree with cuts and apply the RoundUp into the cuts. I dilute the roundup 50% with water because the stuff is pretty syrupy if you don't and I figure it gets sucked in better. OTOH it runs off easier too so maybe undiluted is best. It does squirt better when diluted as the syrup tends to dribble instead of squirt.
