Treating Bermuda Grass Rot: Identification and Management

Bermuda rot refers to several fungal diseases. Common types and treatment:

Major Pathogens

• Large patch (Rhizoctonia solani) – Circular brown patches, spring/fall.
• Brown patch (Rhizoctonia zeae) – Similar, warmer conditions.
• Gray leaf spot (Pyricularia grisea) – Gray lesions on blades.
• Dollar spot (Clarireedia homoeocarpa) – Silver-dollar spots.
• Take-all root rot (Gaeumannomyces graminis) – Root decline, yellowing.

Integrated Management

1. Diagnose: Submit sample to extension lab for precise ID.
2. Fungicide: Apply labeled product (e.g., azoxystrobin, propiconazole) per label.
3. Cultural practices: Deep, infrequent watering; proper mowing height; balanced fertilization; core aeration; remove diseased clippings.

Prevention through good turf management is most effective.
