I use Pathclear which certainly does the job for me.  Takes a couple of days
for weeds to die and go brown.  I just leave the dead weeds and they seem to
disappear of their own accord (probably blown & washed by weather)

I have an old watering can which I used to mix a load and then use that to
keep topping up a pump action sprayer - seems to be reasonably economical.

It is supposed to last up to 3 months before weeds start growing back again
which is pretty much what I get (i.e. "it does exactly what it says on the
tin")
