Fairy Ring is a unique disease as its symptoms are not directly caused by fungal pathogens. Instead, the Fairy Ring pathogens cause symptoms indirectly, by changing the chemical and physical properties of the soil.
Fairy Ring can present in rings or arc shapes or irregular patterns. Type II and III symptoms are not devastating to turf, however they do detract from uniformity and can affect playability, and in most cases management is required.
As the causes and symptoms can vary, curative fungicide applications can be unreliable. For the best control of Fairy Ring, a preventative strategy should be used.
