Got this growing all over my potato patch. What is it and can I ignore it.

I'm not sure what it is, but it looks quite vigorous so I'd try to pull out as much of it as you can. It will be competing with your spuds for water, nutrients and light

Dreadful plant and a nightmare to get rid of once it's well and truly established.
