can you post a picture of some individual leaf blades from the junction between brown and green grass, if you have a camera with macro capability.
sooby said:Can you lift a section of the turf near the edge between green and dead and see if there are any large white grubs in the soil? Process of elimination because it's probably not that if it's been in exactly the same place each year and you've never had skunks digging there (unless the fencing is keeping them out).

5 yrs. same spot.
Think @Cal_Sue`s `chemical` train of thought possible. Previous residents some sort of spill.
If no insects or disease maybe remove dirt and replace with clean topsoil.
sooby said:If it was a previous chemical spill we'd have to figure out why the turf is OK in June but not in August.
