I'm not sure what variety we have up here but a little Outlaw wilts it down fast.
I believe Outlaw is a version of Banvel?
Glyphosate does a good job. But it takes a couple of days to see that it's working. That premixed poison ivy killer is glyphosate mixed with some type of defoliant and it will pucker it up overnight. But good old glyphosate will take it out all by itself. The results are just not as immediate.
