Glypthosate dangers
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'... -- Rusty Direct reply to: horrid dot squeak snailything zetnet point co period uk Separator in search of a sig |

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 think the farmer's mistake is because he will be used to dealing with other sorts of phosphates as fertilisers. I'm sure. But you'd think he might have heard others refer to it correctly, and wondered, innit. -- Rusty Direct reply to: horrid dot squeak snailything zetnet point co period uk Separator in search of a sig |

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?

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.

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