I've done the preemergent seeds a month ago, also 2,4-D spray. Pretty much only thing left is what is pictured. What type of weeds are they and how do I get rid of them? TIA

what type of grass do you have?
Pic 1 is Bermuda or torpedo that needs to be cut. Nuke it and start over.
Pic 2 is poa annua, which will be dying out with the heat soon.

Looks like torpedo grass
PITA to get rid of. Spreads everywhere like crazy.

Pic 1 looks like the worst case of torpedo I've ever seen. round up your entire yard and then light it on fire, then round up again, then pour concrete over the entire area, then you have a very slim chance it won't come back. Good luck though.

I agree with this - both pics. If you have a centipede lawn you have some options if it is torpedograss - if not centipede I don’t know what to tell you. Send your top photo to Dr, Ron Strahan, weed specialist and professor, with the LSU AgCenter rstrahan@agcenter.lsu.edu and ask him for an ID from pic 1. Tell him you can send additional photos if needed.

He’ll need to know what type of lawn grass you have to recommend control options, so provide him that info.
