Key Distinguishing Feature
Depending on the severity of the disease outbreak, symptoms can range from single tillers with yellow or red lesions to the typical 50 to75 mm irregular yellow-bronze shaped thin/bare patches. These patches can be numerous and join together in severe outbreaks. Numerous black fruiting bodies of the fungus can be seen on the foliage as the disease progresses.
Often anthracnose will be observed as a foliar blight, in which the turfgrass leaves are noticeably infected appearing either yellow with possible red lesions.
Depending on the severity of the disease and environmental conditions, the disease also has the ability to significantly affect the turf plants crown and root system. Anthracnose is seen within certain warm- and cool-season turfgrass species.
