Someone needs a good lesson in herbicide applications also.
Before you take in more responses. Make sure you get the better pictures for responders. Pulling up a couple of runners trying not to damage the roots. Lay them on the blacktop to ensure visibility so all can see the nematode activity before they give any product suggestions. I can not suggest any products at this time or tell you if these areas will survive. They can but unless you get proper cultural practices implemented most products will give false hope.
Start with correcting your irrigation management as well as keep that blade sharp and HIGH.

When you say pull up a couple of runners without damaging the roots, I don't know what a runner is?Can you clarify what exactly needs to be pulled and shown on the blacktop for the picture you would like to see. Thank you.
