Hello, I planted a new lawn (fescue k31) 3 weeks ago and am afraid that watering too late in the evening and hot weather caused a fungus that is wiping out all of my hard work and $$. I live in Maryland, I took off of work for 2 weeks to do this and busted my @$$. The property had not had a lawn in 20 years, I hand picked weeds for 2 days straight on my hands and knees, the list goes on. Anyway, it started in small circles with the cotton like fungus and ends in small brown patches of dead grass. It is slowly spreading in the front and back yard, I put down scotts lawn fungus control. If it is pythium I have read I need subdue maxx which is high dollar as you know. Can any of you please help me diagnose and treat this problem? It is heart breaking, I have attached pictures and thank you ahead of time. (pics load slow please be patient) This next picture is the latest taken today one week after noticing the patches.
