Weedol pathclear on concrete drive

I've got some stubborn weeds growing out of cracks in my concrete drive, and by the house. I bought this to use on them, but noticed the instructions say not to use on concrete in case of run-off. Would I be better using something else here?
I've tried to avoid weedkiller in the garden, but these weeds just keep coming back! Want to avoid causing problems with this product, though

    If you have it in a sprayer you can target the weeds.
    Run off is only a problem if it runs off into your or your neighbours flower beds.

    Or if you apply it so liberally that it washes off you driveway into the gutter, down the drains and into the mains drainage and onwards into a watercourse.

    Thanks! It'll be cautiously applied from a spray bottle, and well away from any flowerbeds. Sounds like it should be ok then!

    Got round to doing this now we finally have a dry spell :) I ended up walking over some of the sprayed area while it was still wet. It'll have dried by now, of course, but do I need to worry about transferring the Weedol from my trainers to other parts of the garden? The active ingredients are glyphosate, oxadiazon and diflufenican. I'm guessing now the Weedol has dried this shouldn't be an issue?

    If it was dry you should be fine.  If not you may see some dying off in footprint shapes.

    Glyphosate, once dry-ish is probably not going to transfer much from the bottom of footwear.  If in doubt, make sure to spray or wash any areas you may have walked on with clean water.
    Like a pillock, I got carried away with the pressure sprayer and a cloud of glyphosate spray went over a Euonymous.  I just picked up a small hand sprayer and filled with water.  Sprayed it all over the foliage to dilute any glyphosate down.  Non-issue.
    Glyphosate will break down in the soil, so it doesn't have a lasting or preventative effect.

    Diflufenican is something that does sit in the soil and act as a preventative to things growing.  How effective it really is is up for debate, however.  I'm not sure about this one, but I'd hazard to guess there will only be minimal transfer from the bottom of footwear.

    If you were to lift your foot up and spray the bottom of your shoe, then go and walk about on the grass, re-apply and walk across a flower bed, I am sure you'd do more damage to the flower bed from trampling over it.  The grass might turn brown in places after a few weeks form the glyphosate contact.  If you managed to avoid plants in the flower bed and just walk on the soil, I doubt Diflufenican would be in a high enough concentration to worry about.
