Symptoms and Causes

Fairy ring is unique because its symptoms are not directly caused by fungal pathogens. Rather, pathogens cause symptoms indirectly by changing the chemical and physical properties of the soil. Because causes and symptoms vary, preventive applications provide the best control.

Preventive Fairy Ring Assurance Program

When you follow the prescriptive fungicide program developed by Syngenta experts, tailored to your region as noted below, you are guaranteed season-long fairy ring control.*

A Preventive Strategy

Because fairy ring in turf causes symptoms indirectly by changing soil properties, curative fungicide applications can be unreliable. Once symptoms appear, suppression requires additional steps, such as cultivation and/or a soil surfactant application, to correct soil properties and encourage turf recovery.

That's why a preventive strategy should be used.

For best results, follow these key recommendations when planning your preventive fairy ring control strategy:

  • Maintain regular, preventive applications throughout the season.
    • Initiate applications early in the season when soil temperatures reach 60°F.
    • Deliver the active ingredient to the infested zone of the soil profile.
  • Apply soil surfactants regularly to maintain soil conditions and turf health.
    • Preventive fungicide applications do not require tank-mixing with a soil surfactant, but curative applications generally do.
  • Determine how deep the fairy ring infestations are for watering-in product applications.
    • 0.15" of irrigation is needed if limited to the thatch layer.
    • 0.25" of irrigation is needed if 2-3" deep in soil.
  • Repeat applications on regular intervals to maintain consistent suppression in the soil.
    • Fungicides are a long-term, preventive approach.
  • Rotate fungicide classes.
    • Briskway, Velista and Posterity brand fungicides will provide season long control that protects your course from fairy ring.
