Common turf patch diseases include Yellow Patch (Rhizoctonia cerealis) and Summer Patch (Magnaporthe poae), as well as Necrotic ring spot. (See Necrotic ring spot)These diseases are caused by fungus that affects the roots of the grass.
What turf patch diseases look like:
Turf patch diseases are generally noticed as small circular patches or rings (6” – 12” in diameter) of straw yellow or reddish-brown grass that suddenly appear in the lawn.
How to prevent turf patch diseases:
● Aerate your lawn annually. Aeration helps minimize soil compaction and thatch which can be factors that cause turf patch diseases.
