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?

Regards,
Emrys Davies.

I suspect that it depends how clean the concrete path is. It won't take
very much clay soil dust to adsorb the glyphosate but until the stuff is
bound to clay it is water soluble, mobile and still potentially active.

And grass is exquisitely sensitive to glyphosate so you do have to be
careful not to walk across a lawn with boots wet with the spray.

I have never had a problem with spray on concrete path joints migrating.
YMMV

But for a concrete path with joints something a bit more noxious like
"PathClear" may well do a better job.

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'...

The OP did say it was on concrete paths rather than on soil, but I
think the answer will be the same because having dried out and then
been further diluted by rain it will be very much weakened.
I think the farmer's mistake is because he will be used to dealing
with other sorts of phosphates as fertilisers.

It will be the same: if it doesn't form a (triangular) bond with the
actual concrete, as soon as it is washed into the soil, it will bond
with that and become harmless.

I'm sure. But you'd think he might have heard others refer to it
correctly, and wondered, innit.

What about the grass with which it comes into contact before it reaches
the soil. Would you kindly confine your remarks to Glyphosate which has
dried on concrete, has subsequently been wetted by rain, then trodden on
by shoes which in turn have then trodden on grass?

Emrys Davies.

Yeah - it'll destroy every green thing in sight!

When the Romans destroyed Carthage, they poured glyphosate on the ruins.
They then walked on the ruins with their caligae and tramped all round
North Africa and Sahara. Look what it's like there now!

Probably just a mistake.

An old chap was saying to a friend of ours he had finally bought himself
what he'd wanted for years, a Jezebel. Keeping a straight face our friend
asked a few questions and he had actually bought a Gazebo. :-)

Perhaps he had a Jezebel for the Gazebo. Lovely story!

I used it this p.m. Emrys and I too have walked on grass, (not on
water mind you) I have also sprayed some awful clinging stuff
climbing up some bushes, I put a tray behind it to protect the foliage
and let it have all of one barrel, hopefully it will die off soon.

I thought it was salt. Boy they must have really hated the Carthaginians
considering the price of salt in ancient times.
