I bought some path weedkiller from Wilkies but it was rubbish. Can anyone
recommend a cheap but powerful path weedkiller that does the job in a

None of the modern formulation pathclear type persistent weedkillers are
particularly effective. You may as well use glyphosate.

The active ingredients that did work have mostly been banned.
