Zone 9b, with a Zoysia lawn, and it’s been cold recently.
Clumpy grass has started growing in an area where generator heat killed the Zoysia during the summer. What type of grass is this, what should I use to kill it, and at what temperature should I treat it?

Figuring out what type of grass you have can be tough. You need to look for details that someone who doesn’t know what to look for would probably miss.
Here is a great beginner guide on this topic
Your task is to find everything in common between the picture you shared and the one the person who posted this shared. Then check out this page to see the features you identified that suggest it is poa annua

In the bottom left of the first picture, to the left of the dead leaf, you can spot a seed head.
I agree this looks like poa

Thanks now I see it
That is Poa annua. Since you mentioned you have zoysia, glyphosate will not work for you

That makes sense for this time of year.
I guess I will just pull it since the cold won’t stick around for long

I wish I could pin other people’s comments because this is absolutely the right answer
It’s poa.
You could try using a herbicide called Revolver. It is really expensive.
Keep the seed heads down, wait for temperatures over 80 degrees, or just pull it out

Is Revolver safe for all warm season grasses
@Jai
No it is not safe for centipede or st. Augustine. Monument herbicide is a better choice and they offer packs for treating 1000 square feet

Thanks for the info
The way it grows suggests this is poa annua, the best method to control it is by using a strong pre-emergent treatment. This weed becomes hard and costly to control once it has started growing, so it’s better to strengthen your lawn during the growing season
This is poa, and I have found that hand pulling and careful use of glyphosate works best for me. I have a Bermuda lawn, so it recovers quickly after winter. That may not be an option for you. There are expensive herbicides available, but I would honestly just hand pull and then be sure to apply pre-emergent in the fall to stop them from coming back.
I did hand pulling and applied pre-emergent back in November. Last year my lawn was covered in poa, but now it’s almost gone
@Bailey
What pre-emergent did you choose? I’ve been stuck with the Scott’s blue bag but it doesn’t seem to be working well

Your comment had false or dangerous information
In North Alabama, with Bermuda and zoysia, I’ve found success with poa by using Negate herbicide. It is much cheaper than Revolver, which I have used too. Nothing beats a pre-emergent applied at the right time
Certainty can also kill poa, but usually it takes two to three applications a couple of weeks apart
