What are the typical symptoms of gray leaf spot in turf?

Gray leaf spot is a fungal disease that primarily affects turf grasses, particularly during warm, humid weather. The typical symptoms associated with this disease include areas of the turf that appear scorched and ragged along the edges. The infection usually starts as small, irregularly shaped lesions on the leaves, which then expand and can lead to larger, dead patches. These patches have a characteristic grayish color at the center with a darker border, which contributes to the “scorched” appearance.

Identifying gray leaf spot is crucial for effective management because understanding the symptoms helps in distinguishing it from other turf diseases. In contrast, the other options describe symptoms that do not accurately represent gray leaf spot. For instance, brown spots with fragile edges may suggest different types of diseases or damage, while small green patches in the center and glossy, healthy leaves are not symptoms associated with this particular condition. Recognizing the correct symptoms is essential for diagnosing and treating turf diseases effectively.
