Brown patch is a fungal disease typically affecting bentgrasses and annual bluegrasses. Infected grass appears as patches a few inches to several feet in diameter.
Start with sanitation: remove and dispose of affected material as you find it. Thin dense growth to improve air circulation, and redirect irrigation away from foliage. If the condition persists despite cultural adjustments, your local Extension office can help identify the pathogen and recommend targeted treatments.
