    Is this what take all patch looks like while it's taking out a lawn? I've seen images of the damage I believe but not as it's happening.

    I don't think this is Take all Root Rot cause by the soil borne microbial Gaeumannomyces graminis graminis or Ggg. In fact I don't think Ggg is even in your neck of the woods. But one way to help Diagnose Ggg is to look for the Mycelium which looks like a web on the turf in the earl morning. A more complete diagnoses is done by reproducing or growing the Microbial in a petri dish and matching the Mycelium to know stains under magnification. All microbial mycelium have a signature growth pattern.

    Time to cut more grass, I check back in when need to cool off again

    Florida, this time of year, hi-nitro fert....fungus probably. I see some evidence of spotting on the blades, but a picture before it turned to pure thatch would have been more helpful.

    I am really starting to get concerned about this. I can tell I am about to lose another huge patch of what was healthy grass just a few days ago. It has rained the last couple of days so I haven't been looking too hard but this seem to have happened almost instantly. The 3rd and 4th pictures down show the spot I was writing about last week in the foreground and then the new patch that is seemingly on its way out.

    WOW!!! That is a lot of damage in a short amount of time. Looking at the first pics this area looked to be healthy just 3-4 days ago. The only things I know of that can damage that large of an area that fast is webworm/armyworm, drought or mis-application.

    But I can tell you webworm/armyworm did not cause the first damage.

    Is it possible that problem from over fertilizing weeks ago could lay dormant for so long? I have watered the hell out of it the last 6 weeks and we got a ton of rain mid week.

    It looks like it could be drought stress. maybe some sort of fungus. does it start near the road? may be ground pearls or nematodes. Just some suggestions. I'm not for absolute sure. It does look like st augustine turf. I don't know about Miami but here in NC I don't see a whole lot of that turf around here but we do have some customers with that turf type. I hope my suggestions helped!

    Take a look at some of the good areas while you still have some. See what color the stolons (runners) are. Should be some shade of green, purple or white. I'm really curious what variety this might be.
