Sue, I do not. I have not used it, but we cut some trees out of fencerows for a neighbor when we burned wood and he gave us a spray bottle of brush killer and said "spray this on the cut part". Been too many years ago for me to remember.
My stupid trumpet vine seems to not want to grasp onto the old power pole I have it planted close to. I tied it up...........wind blew it down. Last week I got the Spousal Unit to help...........I held the branches where I wanted them and he pounded in some fence staples. Not tight, just enough to hold them there. I may go put a couple more in after it freezes and the leaves all fall off so I can see what I'm doing.
Mine is planted in such a place that anything undesireable can be mowed off with the lawn mower. Same deal with my wisteria.
Good luck, Sue.
