A question Bob. Doesn't weedkiller poison the soil for growing crops? If
not how long should one leave the soil after first apply weedkiller before
it's safe to sow seed ?

Glyphosate (Roundup) and Paraquat, etc, only act on the plants. Once
they contact the ground they are neutralised as far as any effect on
plants is concerned.

You can plant immediately.

The sort of weedkiller which is absorbed by the roots wouldn't be used
on an allotment - I hope...
