Fairy Ring symptoms can be masked by which management practices?

Fairy Ring symptoms can be masked by which management practices?

• A. Early spring nitrogen fertilizer, adequate watering, and frequent fertilization
• B. Drought stress only
• C. Fungicide applications every week
• D. Mowing height adjustments

Answer: (A)

The idea being tested is how turf vigor and moisture influence whether fairy ring symptoms are noticeable. Fairy ring shows as a circular patch of degraded turf, often surrounded by greener, more vigorous growth. When you boost the overall growth and keep the area well-watered, the contrast between the healthy and the affected turf becomes less apparent. Providing nitrogen in early spring jump-starts rapid shoot growth, helping fill in the ring edge and soften color differences. Adequate watering keeps the soil consistently moist to support that new growth, while frequent fertilization maintains a steady supply of nutrients so the canopy stays dense. Together, these practices make the ring less conspicuous, effectively masking the symptoms. Drought stress would have the opposite effect by increasing contrast and making the ring more obvious. While fungicide applications can control the disease, they don’t inherently mask the symptom pattern in the way that boosting turf vigor does, and mowing height changes alone don’t reliably hide the ring.
