Gray leaf spot is a fungal disease that occurs most commonly on St. Augustinegrass , but occasionally may also be found infecting tall fescue, bermudagrass, centipedegrass, and ryegrass in home lawns. On St. Augustinegrass, the initial leaf spots are small and brown, but they expand rapidly into large, oval or elongate, tan to gray leaf spots, which are surrounded by purple or brown borders. A yellow halo may surround some of the spots, or a general leaf yellowing may occur.

During warm, humid weather, the fungus produces a grayish mycelium and numerous spores on dying foliage, which gives a grayish appearance to the spots. Blades of grass will wither and die if leaf spots are numerous. Under favorable conditions for disease development, large areas of turf may appear to be scorched, resembling extreme drought stress.

    Gray Leaf Spotis A Common Fungal Disease Of St Augustinegrass Recent Wet Conditions Have Promoted This Disease This Includes High Humidity Heavy Dews And Particularly Frequent Afternoon And Evening Rains

    The individual spots or lesions are first seen as tiny brownish spots smaller than a pinhead. As they become larger, they will be circular and then begin to elongate lengthwise along the leaf. The spots will become brown to grayish in appearance. Numerous spots or lesions may be found on an individual leaf. Heavily infected leaves begin to turn brown and wither, usually beginning at the tip of the blade.

    Gray leaf spot can move rapidly during prolonged warm, wet periods. Over watering or irrigating in the evening provides the prolonged period of wetness required for disease infection. For more information on how to correctly water a Florida lawn, visit the UF / IFAS Lawn Watering Website.

    According to the Florida Lawn Handbook, Severity of the disease is enhanced by application of readily available nitrogen fertilizer and is proportional to the amount of nitrogen applied. Select fertilizers that are low in nitrogen or that have slow release nitrogen. Be careful to not overdo it in fertilizing your lawn and do not apply a high nitrogen fertilizer on top of an already infected lawn. Also, some lawn weed killers such as atrazine will increase the susceptibility of the grass to gray leaf spot.

    If the disease outbreak is severe, fungicide may be needed. Look for products containing propiconazole, triadimefon or thiophanate-methyl. Always follow the products label directions and precautions.
