Treatment for Red Thread
I'm looking for product suggestions to treat red thread in the lawn. The lawn is 40,000 sq. ft. so I will need a fair amount. Preferably a granular.

It's just azoxystrobin + propiconazole at prevention rates and the combined modes of action kills the red thread. If you need granular that's Headway G. Be prepared for some insane sticker shock for treating 40k sqft of lawn at label rates.
I think w/ a lawn that big you have to attack culturally and not chemically. Fungicides are really expensive. Make sure that the area gets enough direct sunlight if possible so the blades can dry out. Keep mower blades sharp. Maybe use fungicides where it is worst after doing these things.

Let it go. Red thread suggest a N deficiency. It's purely cosmetic and will grow out. If it's really bothering you use some starter fert. The N will cure it.
Yeah I just had a 30-0-6 applied 3 weeks ago. Unfortunately it didn't seem to help. Threw down some Milorganite last weekend, and just sent out a soil savvy test.
Take a pic when you get a chance. I had some and put down Milo and it was gone
