All turfgrass species are prone, although greatly fertilized, overwatered turf is most susceptible. 2 stages of the disease, each brought on by a various fungus, happen throughout the year. Drechslera leaf spot occurs throughout cool, wet weather condition in the spring and fall.

Bipolaris leaf spot occurs throughout hot and damp conditions during the summer season, and red or pink-colored sores can blight and stain the turfgrass stand. With both leaf area illness, extreme infection can result in plant thinning or death.
