I have grown patches in 2 year old sod. tall fescue. I assume it's rhizoctavia (if I'm saying this right)
Ferti-lome Natural Guard Copper Soap Fungicide will not work on Rhizoctonia or Brown Patch Fungus. If you are treating for that disease I would use Clearys 3336 then rotate to Azoxystrobin or Eagle 20.
