Can someone help me identify what this disease is. I take care of my elderly next door neighbors' lawn. It started last year along the patio and has spread this year and is starting to creep further out especially around the downspout. I dug a few test patches out to check for any insects/grubs and didn't find any so that leads me to believe its some sort of fungus. The rest of the lawn seems to be healthy and the bermuda has been thriving everywhere now that our nighttime temps are staying around 70ish. The lawn was fertilized at the First of May with Lesco 24-2-11 and is due for another application in the next two weeks. I'm in North GA so the soil is obviously red clay. No irrigation system so the only irrigation it gets is the afternoon thunderstorms we've been having lately. The weather has been really funky here in the last year so I'm sure that has added to it.
