"Deep summer is when laziness finds respectability." - Sam Keen

It’s hard to eradicate with cultural methods, with its creeping deep rooted rhizomes and may need a glyphosphate such as Roundup to deal with it. The problem with a non-selective weedkiller is the danger of killing plants around the weed. Hoeing at the base now, and then digging out the roots in autumn is a good alternative and placing tall bamboo canes for the Bindweed to grow up, where it can then be safely sprayed, is another tip.
