Bindweed is very susceptible to Glyphosate (Round-up or Resolva).I eradicated mine in one season.http://www.allaboutallotments.com/index.html
I don't believe the roots live more than a year, so it's susceptible in the spring when it's mobilising the starches stored in its roots and before it's put on much green grown. Dig it up then and it's very weak.
