The drought conditions continue to minimize most disease problems. Many golf courses are experiencing stress and drought dormancy on fairways with excess thatch.
Irrigation has difficulty keeping such areas watered sufficiently.
Several call have asked about small translucent worms in the thatch. In addition, the appoaching cold weather will reduce nematode populations naturally. It may be best to overseed thinned and weakened areas with bentgrass at this time of year and given the relatively dry weather. Rust is prominent in many lawns. Rust infections should be mowed away before the powdery orange spores appear under optimal conditions.
