Over 77 °F (25 °C), the growth rate of the fungus decreases significantly, and it ceases at 85 °F (29 °C). 8 Turf grass that is poor in nutrition and are slow growing are areas that are more susceptible to red thread disease. 2 The fungus grows from the thread like red webbing structures called sclerotia. 1 The sclerotia can survive in leaf ...
Pythium disease, also known as "Pythium blight," "cottony blight," or "grease spot," is a highly destructive turfgrass disease caused by several different Pythium species. All naturally cultivated cool-season turfgrasses are susceptible to Pythium and if conditions are favorable to Pythium it can destroy a whole turfgrass stand in a few days or less. [1]
