Symptoms Large arcs or rings of very green grass, dead grass, mushrooms, puffballs, or a combination of these symptoms. Remove soil cores, spike or force water into affected areas to allow nutrient and water penetration. Avoid overfertilization in an attempt to mask the green rings. Soil fumigation or rototilling and replanting may eliminate fairy rings. Turf Affected St. Augustinegrass Symptoms Oval or circular tan lesions that are bordered by purple to brown margins develop in warm, wet weather.
Leaves wither and die if many lesions develop, giving the turf a brownish color.
Management Avoid excessive fertilization with nitrogen when warm, humid weather is expected. Avoid late afternoon and evening watering. Prune trees and undergrowth to improve air movement and light intensity. Turf Affected Bermudagrass Symptoms Dark, circular, or oval-shaped lesions develop on blades and stems. Some lesions become red, purple, or tan with dark margins.
