In Newnan, Georgia dollar spot disease is caused by the fungal pathogen sclerotina homoeocarpa.  Dollar Spot is a foliar disease, meaning it affects the leaf tissues but does not affect the grass roots or crowns.  Dollar spot usually occurs in the spring when daytime temperatures are warm and humid followed by cool nights.  This type of lawn disease affects both warm season and cool season grasses.  During the early stages of dollar spot, affected areas of your turf stand may appear water-soaked or wilted resulted in small circular areas of blighted turf.  Spots are usually about three inches in diameter or about the size of a silver dollar, hence the name dollar spot disease.  These symptom usually result in reduced turf quality and appearance.  Through cultural practices the severity and occurrence of dollar spot in your Newnan lawn can be minimized. Minimizing leaf wetness is key as this makes the environment less favorable for the pathogen.  This can be achieved by irrigating deeply and infrequently.  Watering should also be done during the early part of the day.  Watering during late afternoon or evening prolongs the amount of time leaves remain wet, thus promoting disease.
