What Type of Fungus or Disease Does My Lawn Have?
Oklahoma’s climate and environmental conditions can make lawns susceptible to various fungal infections, especially during rainy spring or fall seasons. Many people don’t realize that their lawn is growing fungus until the disease has spread throughout the grass, which is why it’s important to keep an eye out for the common types of lawn fungus in our area:
Brown Patch
This fungus is most common in warm and humid weather, and it causes patches of brown or yellowish grass throughout the lawn. The patches are often circular or irregular-shaped with a dark outer ring. Grass blades along the patch’s edge look water-soaked and may be covered in lesions.
Dollar Spot
If your lawn has poor drainage or has been overwatered, you may run into this problem – especially during warmer months of the year. This fungal infection gets its name from the small, tan, and round spots it causes, which are about the size of a silver dollar. The affected patches of grass may have tiny reddish-brown lesions on the blades.
Powdery Mildew
As the name suggests, this fungal infection causes a white and powdery growth to cover the grass blades. It can make your entire lawn look grayish in color, and it’s most obvious first thing in the morning. This mildew thrives in cool and damp environments.
