What is the common lawn disease characterized by brown patches in turf?

Brown patch disease is a prevalent lawn disease that manifests through irregular brown patches in the turf. This fungal disease is primarily caused by the fungus Rhizoctonia solani and thrives under specific environmental conditions, such as high humidity, warm temperatures, and excessive nitrogen fertilization.

The symptoms of brown patch disease typically present as circular or irregularly shaped areas of brown, dead grass, often surrounded by a darker green border. This wilting and browning is a direct result of the infection, which impairs the grass's ability to absorb water and nutrients effectively.

The identification of brown patch disease is crucial for proper lawn management and treatment. Unlike other diseases listed, such as leaf spot or red thread, which can produce different patterns and symptoms in the grass, brown patch is specifically noted for its distinct brown patch appearance, making it easier for landscape professionals to diagnose and address effectively.
