Weed identity and means of killing needed for newbie to group

That looks like Dallisgrass to me. You can put some Bayer Advanced=99 All-In-One Weed Killer for Lawns on it.

I think this is a cool site for identifying weeds. I don't know how comprehensive it is though.

Dallisgrass it is! Thanks! Now, unfortunately, your weed website doesn't advise on what weedkillers to use but as I've already got Bayer Advanced, I'll try it.

I have another one with yellow flowers:

thanks

I haven't been successful removing dallisgrass using weed killers. I usually have to dig or hoe them out. I have a weed removal tool that pulls these things out pretty quickly. If it's a huge clump, I remove it and throw a piece of tall fascue sod on it.

It looks like rather wilted black medic. Or maybe hop clover. (I think I can see some rolled leaves at various places in the photo.) It can creep through the grass under mower height.

Anyway, that's my best guess. I used to have some in my lawn, which I hand-pulled. This involved finding the sprouting point and unweaving long runners from the grass.

Still invades occasionally from the neighbor's lawn.

(He mows too short, with a dull blade, and cuts off too much at once, giving a dramatic illustration of how the most important part of of lawn maintainence is proper mowing.)

Are you talking about using a selective herbicide or a non-selective one, like Roundup? Many grass type weeds do not respond to the typical broadleaf herbicides, because they are similar to the desirable grass. And some can't be treated with anything at all without killing the grass. However, Roundup applied carefully to the clump of grass followed by overseeding should work and would be less work than digging them out.

Ya...I figured black medic. I bought some Spectricide weed killer at Longs Drugs yesterday for it for $5. It claimed to start getting immediate results, which it did for the black medic (they turned brown almost immediately). The dallisgrass turns black on some leaves but not others even though I 'soaked' it. But that's all so far. The label says dallisgrass is one of the weeds it kills so I'll wait.....or.....I might just dig them out.
