Necrotic ring spot patches are described as circular to arc-shaped. What is another way to describe this symptom?

• A. Circular to arc-shaped patches of dead or dying turf
• B. Linear bands of healthy grass
• C. Small irregular healthy patches
• D. Random drought-stressed zones

Answer: (A)

Necrotic ring spot shows turf that dies in circular or arc-shaped patches, so describing it as circular to arc-shaped patches of dead or dying turf best captures the distinct ring pattern this disease makes. That ring or curved-band appearance is a hallmark, often with a healthier center or a dead outer ring, which sets it apart from other patterns. The other descriptions don’t match the characteristic ring form: linear bands would be straight lines, small irregular healthy patches miss the ring shape, and drought-related patches tend to be irregular and tied to moisture rather than forming round rings.
