Red Thread and Pink Patch often occur together. These disease are some of the easiest to identify. Late state Red Thread lawn disease produces bright pink to reddish color fungus with a thread look. Pink Patch develops a gelatinous, pink fungus on the lawn.
Red Thread and Pink Patch both attack lawns low in nitrogen. They flourish in west spring or fall weather. And has been known to appear when the snow is melting in the spring.
The disease spends the winter in the thatch and debris. Once the weather starts to warm up, the disease becomes active. Once the disease is present, it can spread by mowing. Collecting clippings and disposing of them can slow the disease.
Maintaining nitrogen levels will help prevent the disease from becoming active. Proper fertilization and nitrogen levels will help your lawn recover.
