CONTROL GUIDE
Fairy Ring Control Guide
Fairy ring is one of the most challenging diseases/maladies to control in turfgrass settings. The organisms that cause fairy ring symptoms feed on thatch and organic matter, and often live in the soil, making it difficult to reach them with typical fungicide application strategies. Controlling fairy ring effectively requires a multi-pronged approach using cultural practices, chemical fungicides, and water management strategies to address the environment, food source, symptomology (hydrophobicity), and the organism itself. Alongside cultural practices to reduce thatch and organic matter, proper nutrition to address deficiencies is an important factor in managing or masking fairy ring symptoms. Water management is critical in reducing soil water repellency that occurs in areas where fairy ring fungi grow. Wetting agents like SurfaceRx™, Fleet®, and Symphony® are examples of effective surfactant technologies that can help improve water infiltration and distribution, and assist in effectively delivering fungicides to the target zone.
CHEMICAL CONTROL
Application timing for fairy ring begins in the spring when soil temperatures taken at 11:00 am at a 2” depth average 65–70°F on warm-season turf for five consecutive days. These applications should be watered in with 0.125” to move fungicide down to where the fungi are active.

Fairy Ring and Rhizoctonia zeae Prevention • Initiate applications in spring when soil temperatures are consistently above 60°F and turf is actively growing (typically April). • Apply subsequent treatments on a 28-day interval. • All applications should be watered in immediately with at least 0.15” of irrigation. • OPTIONAL — Where there is a history of “mini-ring” caused by Rhizoctonia zeae add Medallion® SC fungicide (2 fl oz/1000 ft²) 14 days after Applications 3 and 4.
