Circular patches with green centers confirm brown patch. It favors high humidity, temps above 80°F day/60°F night, and prolonged leaf wetness. Over-fertilizing, over-watering, and mowing too low worsen it. Correct cultural practices first; if needed, propiconazole or thiophanate-methyl are effective fungicides.
