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.

Ideas?

Cut it off and paint "Roundup" on the cut stems.
Kills it easy,

How does that work when it's only absorbed through the leaves?

BTW, you have to apply the roundup right after cutting ie when wet with sap
If it has dried off, cut it off again lower down.

It was trimmed today and I won't be able to do anything more until Friday.

So on Friday I'll get the loppers out again, trim another inch off where
I can, and paint the Roundup on the edges straight away. That should do
it. Fortunately there's nothing in the vicinity that needs protecting.

Thanks everyone.
