Is it Zoysia and Should I Kill it?

Question

Is it Zoysia and Should I Kill it?
Back in 1992, we moved into this new home and the yard was a complete weed patch and the builder only seeded a small area extending out from the house. The other 1+ acre was weeds and some grass. I killed the entire 1.2 acres with Vantage and Round Up and re-seeded with a mixture various Tall Fescues ending up today with pic5. Since then I have kept 95% of the weeds out and have applied crab grass and grub control and fertilized twice a year. I have noticed what I think is Zoysia spreading in various areas. I first noticed it a few yrs back. For instance, grass10 is up front by the driveway. Grass11 is across the other side of driveway about 100 feet away near a tree. The largest area is seen in pics grass8,9. I am not sure if it is Zoysia. If it I, I don’t know how it got in my lawn and how it shows up in different areas.

I am wondering if it makes sense to kill it off since I spent the time getting my lawn in shape and maintain it or let it go? I assume it would spread more? I was thinking of killing the front by the driveway, grass10 and some of the larger area like grass9 and a bit each year as it is costly and time consuming to do many areas at once. I also have to prepare seed and area after a tree is taken out that is about 15 feet in diameter.

It can be very difficult to distinguish between some grasses, although I would have to agree that it resembles Zoysia.

This comes with many pros and cons. It will be a battle to remove it, but it will be a battle to keep it alive in cooler weather.
