For homeowners, recognizing the signs of these ailments is crucial to keeping yards lush and green.

In this comprehensive guide, we’ll explore the most prevalent lawn diseases in Western PA, familiarize you with their symptoms and identification, and discuss the best prevention and treatment methods. By the end of this post, you’ll be equipped with the knowledge needed to protect your turf from the threats that can turn your vibrant green lawn into a patchy, brown mess.

Common Lawn Diseases in Western PA

Understanding the types of lawn diseases that frequently occur in your region is the first step in effective management. Below, we’ll spotlight four major lawn afflictions you’re likely to encounter in Western Pennsylvania:

Red Thread

Red Thread Disease

Red Thread is a fungal disease that attacks cool-season grasses, particularly during humid, spring or fall weather. It is caused by the fungus Laetisaria fuciformis and manifests as pinkish-red threads that extend from the leaf tips, giving the lawn a scorched appearance. It can weaken the grass, making it more susceptible to other diseases and environmental stresses.

Visible signs of Red Thread include light pink or red thread-like structures on the lawn that give the grass a discolored or scorched appearance. Infected areas may initially turn light brown or reddish before the threads are visible. In severe cases, blades of grass may have entire sections withered or bleached out.

Dollar Spot

Named for its characteristic silver-dollar-sized lesions, Dollar Spot tends to arise in the late spring and summer months and is caused by the fungus Sclerotinia homoeocarpa.
The most identifiable trait of Dollar Spot is the straw-colored and sunken dieback found on grass blades, which can form irregularly shaped spots about the size of a silver dollar. In advanced stages, grass in these areas might become entirely denuded, leaving only a tuft of grass at the center of each spot.

Leaf Spot
Leaf Spot is another disease that affects cool-season grasses in Western PA and fungus Drechslera. It appears as small, reddish-brown spots on the leaves and can cause severe damage if left untreated. The infection usually occurs during warm, wet conditions and can spread quickly throughout the lawn.

Symptoms of Leaf Spot often appear as small to medium-sized brown spots on the blades of grass, sometimes with light-colored borders. The spots may merge over time, forming large patches of dead or dying grass. You may also notice a dark-brown, slimy substance at the base of affected leaves.

Prevention and Treatment Strategies

The best defense against lawn diseases is a good offense. By implementing proper maintenance and early intervention strategies, you can protect your turf from the scourge of common lawn diseases.

It’s important to remember that even the best lawns can get diseases under the right weather conditions. In Pittsburgh, we often experience weather conditions that can cause lawn disease, such as high humidity, warm temperatures, and frequent rain or dew. These conditions create the perfect environment for fungal growth.

Cultural Practices for a Healthy Lawn

Cultural practices are fundamental to preventing the spread of lawn diseases. Keep your grass healthy by following these essential guidelines:

Mowing Practices: Maintain a mowing height that’s appropriate for your grass type, and never remove more than one-third of the blade length in a single session. This will keep grass from becoming stressed and more prone to disease.

Watering: Water deeply and infrequently, preferably in the morning, to allow the grass enough time to dry out during the day. Avoid overwatering, as soggy conditions can encourage disease development.

Aeration: Regularly aerate your lawn to reduce thatch and improve air circulation, which can help prevent diseases like Dollar Spot and Red Thread.

Fertilization: Apply fertilizer according to a schedule that corresponds to the needs of your specific grass type, and avoid over-fertilization, which can lead to lawn diseases.

Fungicide Applications: This type of application is necessary when the disease is progressing rapidly and causing significant damage to your lawn. Consult with a professional for the appropriate fungicide to use for your specific lawn disease.
