What is this and how do I kill it?

Google Lens inconclusive. It's all over my driveway. I have so far tried patio magic and glyphosate.

Thanks!

You need proper glyphosophate.

Not the stuff from DIY stores / garden centers, but the pro grade.

Basically ~500g/L (50%) or there abouts.
Most places won't sell it to you without a licence, but unfortunately no consumer weedkillers are any good. It's the consequence of regulation and idiots being unable to actually follow instructions and use nasty stuff safely.

(For reference, the consumer product Pathclear mentioned above is 125g/L (12.5%))

I used Gallup 360 from Amazon but did dilute it.

Thanks to all for the advice in this thread. I'll try your various techniques! Loving the idea of setting fire to it tbh .

When using glyphosophate on it are you putting some fairy liquid in to act as a wetter? Its waxy leaves mean it will just bead on the surface of the leaf and not be absorbed properly if not.

No I hadn't tried that. A 'wetter' for something that's already wet is going right over my head!
