Severe Gray Leaf Spot symptoms. Note leaf tip die back.
Many spots can occur on a single leaf, such that severely affected leaves wither and turn brown. No distinct patches are observed, but areas may appear thin. A severely affected turfgrass area may appear as though it is suffering from drought.
Once St. Augustinegrass is established in the landscape, the disease is chronic but not severe. During the summer months, individual St. Augustinegrass plants will always have a few spots on the leaf blades, but the overall health of the turfgrass is not affected unless the grass is placed under severe stress.
