More than likely your yard is not actually a landing zone for miniature intergalactic travelers but you probably have a case of Necrotic Ring Spot. NRS is a common disease in Kentucky Blue Grass, and because the lawns in Spokane are mostly Kentucky Blue Grass there is a strong possibility that you may experience it at one time or another during your stay in the Inland Empire.According to North Dakota State University, "This is a serious disease of Kentucky bluegrass that is especially common on high maintenance lawns. Necrotic Ring Spot is caused by Leptosphaeria korrae, a fungus which is most active in spring and fall, although symptoms may be observed throughout the season. Initial symptoms are patches 6-24 inches in diameter with a mixture of normal, straw- and red-colored blades around the outer portion of the ring, resulting in a "frog-eye" pattern. The roots and crowns of affected plants are covered with black strands of the Necrotic Ring Spot fungus. Thatch may decompose in the patch areas, giving them a sunken or depressed appearance. In warm weather, the red blades are seldom seen. Plants affected in the cooler weather of spring and fall are weakened and very susceptible to summer heat and drought stress. This stress may lead to the death of weakened plants and an apparent resurgence of symptoms, even though the fungus may not be active at this time."
