    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.

    maybe a too much moisture (irrigation);

    Try Cleary Fungicide 3336. May have to do a couple of apps. Don't do too many apps with the same product because fungus will build resistense, maybe two; a good drench with copper sulfate as an alternative wouldn't hurt & it's cheap.

    I'm sure the L&O guys will jump in soon.

    Thank you very much! I am researching the product you recommended and am going to hold off for a little bit to see what others say. The price does not look so bad I will more than likely try it!

    Appreciate your help! :)

    Does the blades have any lesions? If so are they an hour glass shape that covers the leaf from side to side or do the appear to be on one side or the other? How hot has it been? What has the watering schedule been?

    I agree dollar spot. Irrigate less, and mow to 2 inches max to help it air dry.

    I would not have used K-31 for a residential lawn. There are many TTF that are better looking, with similar or better hardiness. Overseed in the fall with TTF.

    Maybe it varies by region, but around here Scott's Lawn Fungus contains the same active ingredient as Cleary's 3336.

    Thiophanate Methyl.
