Have You Ever Noticed Any of These in Your Lawn?

The official start of summer is right around the corner and Killingsworth wants to help you maintain a beautiful lawn. There are a lot of lawn diseases that you may not be familiar with, so we’ve created a list of 10 diseases to help you identify what could possibly damage your lawn.

1) Brown Patch

A fungal disease that can typically be found in all cool season turf grasses throughout the United States. It usually appears on lawns in areas of high humidity and/or lawns that experience prolonged wetness

2) Leaf Spot/Melting Out

A disease caused by a group of fungi. Technically, these are 2 different diseases with similar characteristics and symptoms. Their difference comes from leaf spot being active in the summer heat and melting out being active in cool, wet environments.

3) Dollar Spot

A fungal disease that affects leaf tissue, but does not reach the roots and crowns of turf grass. This disease is most active in warm temperatures with high humidity.

4) Microdochium Patch

Also known as Pink Snow Mold and is typically found on bent, bermuda, and blue grasses. It is common on lawns in cool, wet environments, especially if snow is present. However, snow is not necessary to cause infection. Factors such as cold, fog, and light rain are the most opportune environments for this disease to spread.

5) Fairy Ring

Caused by more than 40 types of fungi, it can affect all species of turf grass in the United States and typically causes damage between early spring and early winter.

6) Necrotic Ring

A fungal disease that spreads in the form of spores. The spores are typically spread throughout the lawn by air, wind, water, and humans. The disease is most noticeable during warm weather.

7) Fusarium Patch

The same as Microdochium Patch (see #4), but it is referred to Fusarium Patch when it occurs in the absence of snow. It thrives in wet conditions with temperatures below 60 degrees fahrenheit.

8) Powdery Mildew

A fungal disease that favors cool-season grasses like blue grasses and fescues. It’s typically active in areas of poor air circulation and high humidity with temperatures around 65 degrees fahrenheit.

9) Gray Snow Mold

Like it’s displayed in the name, this is a true snow disease. It requires at least 8 weeks worth of snow coverage in order to develop in lawns. This typical disease can kill large areas of grass at once, resulting in extremely slow recovery.

10) Pythium Blight

This specific lawn disease thrives in hot, humid weather and spreads rapidly, killing leaves, crowns, and plants. It especially affects creeping bentgrass, annual bluegrass, rough bluegrass, and perennial ryegrass.
