Here are two more I found this morning. The first one I am almost positive is Yellow Nutsedge. The other pics of the other weed I have no idea. Thoughts?

Here’s two more I found in my lawn today. I think the left one is dogfenel and the right is butterweed. Any thoughts?

Good morning - I recently did a KBG overseed of my lawn that is filling in nicely. After mowing to 2 inches yesterday, I noticed this weed in the area near the side of my house. What is it?

Can anyone help with this one? I’ve been looking at grass and weeds and it’s hurting my head how its all starting to look the same.
It pulls up easy like it’s rooted only into thatch with long vine like stolons. It seems to behave like bent grass but it doesn't look the same to me. Is it nimbleweed? Could be a grass and not a weed? Dying/sick KBG perhaps
Thanks

@Buckmaster I can't I'd it. It looks like Zoysia or nimblewill or bermuda. I don't think it is bent and definitely not kbg. It mostly looks like it is all dead in that area.

Thanks for giving it a look. Do you think it could be poa triv? I just learned about that while searching around.

@Buckmaster, I could be incorrect, but that doesn't look like bermuda to me.

@stogie1020 , for pics 1 and 2, are you sure that isn’t common bermuda?

You may be right, although I am not entirely convinced. It was so much lighter than the overseeded Rye I assumed it was a weed, but my Bermuda was not fully dormant when I overseeded. I just dont remember my Bermuda being that wide leafed or having the vertical levels that this has. I will give it a shot of some hose-end weed+feed and if it lives, it's Bermuda.

I assumed that you had a turf type bermuda, and I was thinking that some common crept in somewhere somehow. If you think that it is not bermuda, you might consider Torpedo grass. Torpedo grass can look like common bermuda, and I have read that the blades of Torpedo look wider than bermuda. To me, that doesn't look like Torpedo, but I am not terribly reliable for that ID.

Thanks, I have common bermuda (sigh...). I am going to spray a "weed+feed" hose end bottle on it and see what happens...

This is growing in Fescue. I'm in Alabama but didn't see this until after the weather turned cool. We've had a lot of rain lately. Any suggestions?

@Ironman77 , have you noticed any stolons?
@Wilbursan , for chemical control, I would proceed with triclopyr and a non-ionic surfactant.

TZone SE has 7.72% Triclopyr BEE - would this work? I have plenty of that.

I not familiar with all of the triclopyr formulations, but that should work. Be sure to use the surfactant if one isn’t already in the solution.

One more question. All the advice I can find says wait 3-4 mowings before using herbicide after seeding. Obviously I'm not still cutting grass in mid November so how long after germination before it's safe to use TZone-SE on overseeded Fescue?
