Pythium blight is a well-known disease, especially on cool-season turfgrass. However, it’s also a major problem on warm-season turfgrass, particularly on bermudagrass.
Symptoms develop as small brown or black spots ranging in size from 1/2 inch to 2 inches. These spots can coalesce into large blighted areas quickly if conditions are conducive.
Pythium blight develops on bermudagrass during the fall, winter and spring, but can develop during the summer months under periods of extended cloud cover and/or prolonged moisture. The disease is most severe after major rainfall events that saturate soils.
Pythium blight develops when nighttime temperatures are above 65 degrees F and soil moisture is saturated and/or relative humidity remains high for two or three consecutive days.
Pythium Blight Fungus is extremely widespread in many yards this year!! Fungicides are almost always applied on a curative basis for controlling dollar spot. Both contact and penetrant fungicides are effective in controlling this disease.
