These diseases can occur on several turf grasses, but are more damaging to Kentucky Bluegrass. In the past, some of these diseases may have been referred to as Fusarium Blight, but today are referred to by their current names.
Initial symptoms appear as small spots (2 - 4" diameter) of light green turf. Spots enlarge to form light straw colored circles, irregular patches, and crescent patterns that are 1-2 feet in diameter.
Centers of the patches may contain grass that is alive or dead. When dead, the patches of grass appear crater like or sunken. Patches may overlap to form large areas of blighted turf. Symptoms may also appear as diffused patterns of yellow or brown turf. Blackening of the infected crowns, rhizomes, and roots is also characteristic. Yellow patch on bent grass generally occurs as yellow rings that often recover.
