Can anyone tell what kind of weeds these are? (neighborhood, farm)

[moodong2018]

Hello,

I found weeds in my Bermuda grass.
Can anyone tell what kind of weeds these are?
These weeds have been showing up about two-three weeks ago after pre-emergent was put down in early March.
How to get rid of these weeds?

Thank you,

Looks like rye grass.

But I don't see so well. But I think it is. Light/pale green? Seed heads? Thin round stalks? If so, rye

Was your Bermuda green over winter? Rye grass is commonly used to overseed Bermuda. Scalp it.

Thanks for the information.
Yes, your description perfectly matchs with the ones in my Bermuda.
My Bermuda, three years old, was dormant during winter.
Do you think it is annual or perennial?
Thank you.

I thought it was perennial, but after looking at Waldo's poa informational I'm not so sure that it's not poa and an annual.

I think it is an annual, but acts like a perennial because of the billions and billions (.. it seems like it anyway) of seeds that it drops. If it gets established, it's quite a job to get rid of it. I know this from experience.

You have to put per-emergent on it in the fall which is of course when you are also supposed to seed your yard for regular grass.

looks like your neighborhood was carved out over top of some old farm land. That's straight up farm grass. It's prob goes deep into the soil. the developers prob laid the bermuda sod over top etc.

Thanks for the valuable information.
Is there any way to get rid of the grass now (except pre-emergent in the fall)?
Does herbicides such as Ortho Weed-B-Gone kill it?

Cut it very close. Now that it's getting hot you can encourage the bermuda to outcompete it. The first step is setting your (very sharp) mower blade low low.

I didn't notice the OP had bermuda. It's easier then since there is no reseeding in the fall. Warm grass should be planted in the spring.

The annual bluegrass will die out when it gets hot and disappear during the summer. It's important to get rid of as many seeds as you can before it does. So do like Native_son said and cut it low for the next few weeks AND bag/dispose the clippings. Also there is mechanical removal. (engineer-speak for pull it up. )

Use Surflan A.S. as a fall pre-emergent.
