Here's the pic. Sorry

Looks like it to me. Use Drive XLR8 to kill the crabgrass.

This is indeed crabgrass. Even if you apply XLR8 now, it is going to reappear next year. XLR8 is a post emergent weed killer and will kill the current batch. Since crabgrass is an annual, it will die out as soon the first frost hits the even without using any weed killer. But the seeds from the current batch that are already in the ground will sprout as soon as the right conditions arrive. That is going to be sometime in spring/summer next year. You should apply a pre-emergent in early spring to keep them in check. I suggest using Prodiamine WSG 65. If used as directed it will give you excellent results. Unless you keep on top of it, this stuff will come back. Crabgrass seeds are viable for many years. Will lie dormant in the ground and will sneak up on you any time.

Thanks for the help. Instead of spraying it now would you just recommend letting it die on its own in a few months after first freeze (I'm in NE North Carolina) and applying the pre-emergent in early spring? Or would it help to kill now?

Quinclorac kill crabgrass. It's the active ingredient in Drive XLR8, you can use any brand and it will work.

Some people (reeljake) uses Sulfosulfuron (Sedge Ender) and it works fine as well. People have have pretty good results keep most weeds out of their bermuda with Celsius and Sulfosulfuron. Plus there is no issues related to applying in hotter temps.

Reeljake also uses Dimension with active ingredient dithiopyr as his pre-emergent, I use Prodiamine. With either you want year round coverage to keep ALL WEEDS from germinating. You will need to start your PreM asap to keep winter weeds at bay, then again in Spring for Spring/Summer weeds.

1. PreM: Prodiamine or Dimension
2. Crabgrass: Quinclorac or Sulfosulfuron
3. General weeds (post-emergent): Celsius - 2,4-D will work also but turns grass yellow

If you get the correct products, it won't matter what the weed is, it either will never germinate in your yard, thanks to the PreM, or will die when sprayed with the post-emergent.

What he said. Don't let it die on its own, the problem will only come back worse. Kill them with a post emergent now & get yourself on a consistent preM schedule to avoid future outbreaks
