Re: Fescue Lawn Care | Northern VA
It's always possible that there is more than one thing going on. But there is consensus that you have a fungus. Maybe it will resolve itself and maybe it wont. Treating the fungus will cost a few dollars and take some time but it wont hurt anything. Not treating it might turn out fine, or you could end up with dead patches or you could lose the entire 600 sqft. it's really your call. Personally I would treat it for fungus.
Raking the lawn may result in spreading the disease to previously uninfected areas.

Re: Fescue Lawn Care | Northern VA
While I am not advocating letting an active fungal infection ravage the lawn, I think that the "it won't hurt anything" is stretching the truth somewhat - there is a balance here that needs to be factored into consideration. Broad-Spectrum fungicides kill lots of fungi, and the beneficial fungi that keep many processes working take a hit too. It's not like each microscopic fungus is marked with a sign that says "I'm good fungi - don't kill me". Broad Spectrum is broad-spectrum, and the good take a beating with the bad, just as the beneficial microbes in your gut take a beating when you use an antibiotic.Treating the fungus will cost a few dollars and take some time but it wont hurt anything.

You will need a follow up application. You want to rotate groups of fungicides to avoid resistance. DiseaseEx contains azoxystrobin. I would follow up with Bayer fungus control which has propiconazole in 14 days.
That should stop it from keeping going and avoid more grass blades getting lesions. That should get you to late August when you can overseed the TTTF to repair the damage.
Don’t serially apply fungicides and definitely don’t serially apply the same group of fungicides.
Curing active disease is not a one and done.

FYI - azoxystrobin won't do anything for dollar spot, great for brown patch though. Use propiconazole for dollar spot, you can apply both at same time if unsure what you have. There are a few fungicides that have both azoxystrobin and propiconazole mixed.
