Can anyone identify this weed?
Three weeks since I’ve overseeded and I’m starting to get an infestation of this weed. Any tips on how to remove it?

If you’re asking for chemical recommendations to control grass weeds in a lawn you need to tell people what the lawn is or you’ll end up getting wrong information and killing your lawn. It’s not a one for all situation 👍
It does look like crabgrass, but without seed heads it’s never easy to get a 100% ID. There are a few grassy weeds that can look very similar. I had a look at your journal and it looks like you’re running fine fescue, which does limit your chemical options a bit.
NZLA Meso is one of the better options here. It’s safe on established fine fescue once it’s had a couple of mows or it is at least 4-6 weeks old. It’s labelled for summergrass/crabgrass control and works reasonably well as a post-emergent, especially on younger plants. You’ll likely see some bleaching on the fescue, that’s completely normal with Meso and it will grow out.
To be honest, even if the ID isn’t perfect, Meso is very effective on a range of young grassy weeds, so you’re still in a good position to control it early.

Can you upload a photo of the collar/node and a photo of the ligule? Close up.
@Garry Bainbridge let me know if this is close enough!
I seeded with dark perennial rye last November. Then over seeded with DPR again with a fine fescue mix for the shaded parts.
@Robert Law was meaning more like this. Could be so many things Veld grass, Carpet Grass, Barnyard Grass you need little characteristics to ID them apart. Since you’ve mixed fine fescue in your MDR getting an accurate ID is somewhat pointless as you can’t use many chemicals on blends. You’re limited to giving Meso a crack and seeing if it controls it or pull them out by hand. Make sure that oversow of fine fescue has been mowed a couple of times before trying Meso.
