Brown Patch Fungus in Over-Trimmed Floratam Lawn

A homeowner cut Floratam too short, promoting weeds, and now sees large round brown spots. They reduced watering to once weekly, but spots grow. The expert suspects brown patch fungus. First, verify irrigation coverage by running sprinklers long enough. Second, do a soap flush to rule out insects. If both check out, apply a fungicide labeled for rhizoctonia (brown patch) and sclerotonia (dollar spot).

Proper diagnosis before treatment is essential to avoid unnecessary fungicide use.
