The message
from "Emrys Davies" contains these words:

I know how glyphosate works on a plant and the soil but I am wondering
if it is safe in the following circumstances:

If it is applied to weeds on concrete paths, allowed to completely dry
and then it rains is there a danger that the residue can then be carried
on shoes onto grassed areas and thus cause damage?

No. Once in the soil it becomes locked-in and harmless.

Incidentally, on the Farming Programme recently (IIRC) I heard a farmer
refer to it repeatedly as 'glyphosphate'...
