    This is a 3 year old tall fescue lawn. It was killed and slit seeded.
    I think this is brown patch. Anybody?

    Looks like a fungus, probably brown patch. That stuff is rampant in Va Beach.

    That is what I would say it is. Hopefully you will get some rain out there after you treat it. All the lawns I treated never fully recovered because we didn't get any rain in the subsequent weeks after treating it. Can you say waste of an expensive chemical?

    I say brown patch. It's in lots of lawns around here too. just have to wait till the temps get cooler.

    Maybe, maybe not... look again at the second pic. You'll see smaller more distinct circular patches. Maybe $ spot. The larger patches may have been smaller ones which have merged together. More info needed. How long did it take to get this bad & have you been bagging or simply discharging (spreadiong the fungus?) Has the lawn been recently fertilized (some fungi will spread more rapidly if fertilized)

    Sorry, I don't know where you are, but the first pic makes it look like all the damage is right along the road, and the dead stuff at the edge of the drive doesn't look like fescue. Is this property in a farming community where hay is hauled past?
    Hard to say just by the pics. Check the blades of grass at the perimiter of the dead areas for leaf damage (disease indicators as opposed to bug damage) and check the soil for larvae. Could be brown patch, but it's a bad case if so.

    I would like to see a single blade of grass about 1" away from those dead spots. Then I would know for sure. The spots seem pretty big to be dollar spot so I would lean towards brown patch. Either way it is a fungus.

    It's not one of my accounts. I pass this property everyday and noticed it really bad lately.
    The homeowner mows it himself. I know the guy who seeded it and he tried to get the guy to let him treat for brown patch the first year. The first year, he only had minor areas and reseeded, it looked good. The second year was about the same as the first. This year, it's a real big problem.
    I was asking for a diagnosis because it looks so much worse this year. Here's a couple of more pics.
