What type of disease is Brown Patch primarily associated with?

Brown Patch is primarily associated with a fungal disease caused by Rhizoctonia solani. This pathogen affects a wide range of turfgrass species and is particularly prevalent in conditions of high humidity and warm temperatures. The disease manifests as irregularly shaped patches of brown or straw-colored grass, often during late spring and summer when environmental conditions favor its development.

Understanding the nature of Brown Patch is critical for effective disease management. Since it is caused by a fungus, strategies for control typically include proper cultural practices such as avoiding excessive nitrogen fertilization, ensuring adequate water management to prevent over-saturation, and maintaining healthy turf through proper mowing and aeration. Fungicide application can also be an effective method of control when necessary, particularly when environmental conditions are conducive to the disease’s spread.

Thus, recognizing Brown Patch as a fungal disease rather than a bacterial or viral problem, or something caused by nutrient deficiency, enables turf managers to implement the appropriate practices to mitigate its impact on turf health and aesthetics.
