Killing/control Wisteria

We moved in back in September of last year, and the yard had been neglected for years. Overgrown crap everywhere, but I’ve done a pretty good job so far of hacking everything back and restoring an actual yard. There’s a creek/ditch on the side of my house that is loaded with wisteria, and not matter how much I cut it back, by the following weekend it’s back and creeping over everything again.

I realize it will take a year or two to get everything under control since it’s been running rampant for so long, but is there anything that will kill this stuff back (beside a machete and clippers). The ortho brush killer spray works decently, but I want scorched-earth death upon it
