Necrotic ring spot patches are circular to arc-shaped and range in diameter from which size?

• A. 6 inches to 2 feet
• B. 1 to 3 inches
• C. 2 to 4 feet
• D. 8 to 12 inches

Answer: (A)

Necrotic ring spot creates circular to arc-shaped patches in turf, and the patches typically measure about 6 inches up to 2 feet in diameter. This range reflects how the fungal infection starts as smaller rings and can expand or merge with nearby patches over time. So, patches around a few inches across are possible in early or mild cases, while rings approaching two feet in diameter are common in more developed outbreaks. The other size options don’t align with what turf-pathology guides observe for this disease.
