You could try providing some canes for the bindweed to grow up. I
favour
a combination of continuous chemical attack with dilute glyphosate
and
physical removal of any shoots I see ASAP.

Surely performing that last action effectively negates the use of the
glyphosate?

Not if you leave the glyphosate on for a fortnight first.

The trick to beating pernicious weeds is to keep on hitting them again
and again. It doesn't much matter what you hit them with. Even a stick
will cause them some damage. I generally hit bindweed and ground elder
with weedkiller (either glyphosate or verdone) every time I use the
stuff.

But I use as little as possible so one bottle lasts me a couple of
years. In between applications I physically remove any new shoots that
appear. And gradually dig out the roots. Damaged with weedkiller it is
less likely to survive if small bits break off.
