Thanks. I've heard that glyphosate kills bindweed. Any experience of
that?

Yes, use it on the new allotment where there are a few patches of it. Dug
out as much as possible but it still comes back so am now using the thick
pasty type liquid (Deep Root Weedkiller Gel) with it's own brush which I
just brush on the leaves. Kills it overnight and also does for the roots
eventually after you have painted a few new shoots as they come up (which
get weaker each time they appear). Should be clear by the end of this
season.
