Necrotic Ring Spot is one of the more difficult to control fungal lawn diseases that affect homeowners in White Lake, Michigan, especially during the warmer months. This disease, caused by the fungus Leptosphaeria korrae, creates dead, circular rings in the lawn, often surrounding healthier grass in the center of the ring. Necrotic Ring Spot thrives in lawns that are stressed due to poor soil conditions, compaction, and improper watering. Excess thatch is also common on lawns infected with Necrotic Ring Spot.

To treat Necrotic Ring Spot effectively in White Lake, homeowners should focus on lawn aeration to relieve soil compaction, promote healthy root growth and reduce the thatch layer. Aerating the lawn allows better water and nutrient penetration, which strengthens grass and creates an environment less conducive for the disease to spread.

Maintaining proper mowing practices by keeping the grass at a height of 2.5 to 3.5 inches also helps the lawn stay healthier. Grass mowed at a higher height will generally have a more extensive root system.

Fungicides are often necessary for managing Necrotic Ring Spot, but timing is crucial. Applying fungicide treatments in early spring when the disease is infecting the grass plants can reduce the impact of the disease. Additionally, deep, infrequent watering encourages strong root development, while balanced fertilization provides essential nutrients for lawn health.

Overseeding with disease-resistant grass varieties is also an excellent strategy to minimize the occurrence of this fungal disease. By implementing these lawn care practices, residents of White Lake can reduce the risk of necrotic ring spot and maintain a lush, healthy lawn.
