Necrotic Ring Spot: How to Detect and Manage this Troublesome Lawn Disease

Necrotic Ring Spot is a common and troublesome lawn disease that can wreak havoc on the appearance and health of your turf. This fungal infection primarily affects cool-season grasses, such as Kentucky bluegrass, fescue, and ryegrass. One of the key signs to look out for is the formation of circular or crescent-shaped patches of withered grass with a brown or tan color. These patches are usually a few inches to a foot in diameter and can merge together to form larger areas of damage. As the disease progresses, the affected grass may die off completely, leaving behind unsightly bare patches in your lawn.

Detecting Necrotic Ring Spot early is crucial for effective management. If you notice any signs of discolored or dying grass, carefully inspect the affected area. One distinctive characteristic of this disease is the presence of a dark brown to black ring or arc within the patch of damaged grass. This ring is a result of the pathogen attacking the roots and crowns, leading to the death of the plant tissue. To confirm the presence of Necrotic Ring Spot, you can easily conduct a simple diagnostic test. Simply grab a handful of grass from both the affected and healthy areas and tug gently. If the grass pulls up easily and the roots lack vigor, it is likely that your lawn is indeed suffering from this troublesome disease.

Rust Disease: Tips for Prevention and Treatment to Maintain a Healthy Lawn

Rust disease is a common problem that many homeowners face in maintaining a healthy lawn. It is caused by fungal spores that infect grass blades and create unsightly orange or reddish-brown patches.
