Even if we resod the area the root ball is deep and it sends runners out above and below ground and would come back again. Cutting or pulling it just spreads it. How we got it, who knows. I believe this stuff is spread from an infected lawn when mowed and carried on to the next one. We are working with our lawn care company to control it and to at least kill what is above ground. Anyone have experienced this and was able to permently resolve it?

I do not apply any weed killer to my entire lawn as no matter what you do it will hit plants you do not want to hit. I use liquid weed killers and spot treat only the weeds.
While they claim you can use trimec (24D) on zoysia it does stunt it. In the heat trimec will kill st augustine-HINT
if you have a zoyzia lawn and have st Augustine creeping in spot treat with a strong solution of trimec (1 tbs to a qt) on a hot day. It will damage the zoyzia but kill the st augustine.
What you have is called rocket grass, torpedo grass or??
Anything that will kill it will also kill your desirable grass.
SOLUTION-you buy one of the weed and grass killers. The one I use is 41% glyphophate, I mix 1 tbs to 28 oz water and I use a small paint brush to apply it to the leaves of the weed. The idea is not to hit your grass. The product is absorbed through the leaves-no need to wet the soil.
You do not want to use any of the long lasting products.
I believe the same chemical is in round up. We do the same thing on nut sage which has bu;bs along it's roots-if you pull it you will only have more.
