Now that we can't get Sodium Chlorate what's the best (as in
reasonably cheap + effective) alternative?

I recently used up my last bit of Sodium Chlorate on one part of our
large area of gravel and Pathclear on another area. The Pathclear
seems to have been totally ineffective whereas the Sodium Chlorate
worked well. So I'm not very impressed with Pathclear for a start.

I *want* the weedkiller to stay in the ground for as long as possible
so products that leave 'no residue' are most definitely not what I
want.

It's a big (like getting on for 1000 square metres) area of gravel so
price is quite a major consideration.

My gravel drive is something like 300 metres long. I've used Sodium
Chlorate and I've used Glypohsate. Glyphosate worked out cheaper! One of
those five litre tubs of concentrate is expensive but it lasts a very
long time. The sodium chlorate was no better at killing weeds and new
ones popped up soon after it rained anyway, so it didn't seem to have a
long lasting effect. During Summer I spray the drive every couple of
months. Just don't use Roundup - it is a very expensive way of buying
generic glyphosate.
