Turf affected: All warm-season turfgrasses
Symptoms: This is a root rot disease. The symptoms are usually associated with wet soil conditions, either from excessive rainfall or from irrigation. Poor drainage conditions compound this problem. The symptoms observed on the leaves are the result of fungal activity on the root system. The aboveground symptom is generally a decline in turf quality. Small to large turf areas become a yellow, light green, or brown color and the turf begins to thin out. Roots appear thin and discolored, but are not black and rotted as they are with take-all root rot.
Disease occurrence: Symptoms may appear at any time of the year.
Management: To prevent the disease, improve drainage.
