Why don't you forget about using vinegar as a systemic herbicide and instead use
it for pickling your vegetables?

Thank you, Martin. If you observe the dates of earlier postings you
will see that I decided not to pursue using vinegar. You're right to
suggest it for pickling though. In fact, today, in a bookshop, I saw a
book ENTIRELY devoted to explaining over 50 different uses for vinegar!
A most versatile liquid it seems!
