Fire or a hoe.

"Systemic" types also kill the root to prevent regrowth.
Systemic weedkillers often include "glyphosate (http://en.wikipedia.org/wiki/Glyphosate)".

Sodium Chlorate is good, but you will get re-growth after a while.

As said, systemic weed killers containing glyphosate (eg Weedol™) do a better job, but are very much more expensive and you may need to re-treat some stubborn weeds several times. It rather depends on what you want to kill. If you have a problem with Ground Elder, Ranunculus (Buttercup) or Japanese Knotweed, you may have a few years battle on your hands.

I once had a very long chain link fence, which hadn't been trimmed in years.  I spayed a baseline under that fence with Roundup.  That baseline went bare and sterile for about 3-4 months.  Then the most beautiful moss you ever saw come in and stayed........never had to trim that fence again.

Best chemistry I ever did.

If its Japanese knot weed, you are better of moving. Or maybe get something bigger than a hoe like a mechanical digger, and remove the soil down to a couple of meters. Then replace it with soil free of weeds.
