Is this Bermuda in my St Augustine?

I've spent a couple of weeks trying to figure out what this grassy weed is and I think it might be Bermuda grass. It grows sparsely in a couple of small patches 2-4 ft diameter where it has thinned the St Aug and I see a larger area in my neighbor's lawn right by the edge of mine. These patches are on the same side of my lawn, but not close together really.

Is my identification correct? And if it is Bermuda is the only option roundup and resod? Is Atrazine useful here or a waste of time? What cultural practices control this in St Aug? It seems to grow as tall as the Augustine grass and be more drought resistant.

Thanks for any help,
Scott_WPB_FL

Ms_Surveyor, that picture looks close enough to what I see that I can't rule it out. I don't know why my first sample has such wiry leaves. I took a picture second sample which has very thin blades but not so wiry in case it helps anyone ID it. I think the first sample got a bit dehydrated maybe.

I think the seed head shown in the original photos is consistent with Bermuda.

Scott, That is bermuda. I am not aware of anything that will take it out of SA without killing the SA also. If your neighbor has it, you will have it. IMHO it is a much stronger turf than SA.
Cultural practices - remove from the neighbors lawn and pray it does not come back. Generally it seems that I find it most often in lawns where the irrigation is not up to par and is a spot that receives full sun exposure or is a hot area.

If the area is still small in your lawn ...you could try wiping Round Up on it carefully trying to do as much damage to the SA as you can and trying to push the growth of the SA to close in before the Bermuda comes back.

It has always been my experience that St Augustine will finally choke out bermuda, if the St Augustine is healthy. Am I wrong on this?

Total Irradication will not occur. Don't hold your breath based
on winning One battle. Bermuda will always maintain the upper hand. It is really that tough!
