How to kill a buddleia?

It's growing in the 8" gap between the greenhouse and the boundary fence
(sheep netting). It's distorted the greenhouse frame, breaking one of
the panes. I've hacked back the buddleia and replaced the pane.

Knowing that buddleias like a good prune I'm assuming it's likely to
carry on growing and cause more damage, so I'd like to kill it. First
thoughts are chemical, but I don't know what to use and how to apply it.

Glyphosate or any other weedkiller whenever you happen to be using it
every few weeks will see it off. Bark ringing will slow it down too.

I use the same trick on awkward to reach small trees that get too big
to pull out or are somewhere I can't reach or dig without damaging
something precious. Just protect anything you like from the spray.
