McDonough lawn dollar spot is the most common and persistent lawn disease.   Dollar spot disease affects both cool and warm season turf grasses in McDonough.  This type of disease is caused by a fungal pathogen known as Sclerotonia homeocarpa.  The Sclerotonia pathogen causes leaf blight, or disfigurement to leaf tissue, but does not affect the roots of the turf grass in your lawn.  Dollar spot disease in McDonough lawns is most active during early spring to late fall, during cycles of warm days and cool nights due to heavy dew forming on the turf due to change in temperature. Excessive thatch growth and low mowing height also contribute to the encouragement of disease advancement.  Dollar spot disease favors warm humid weather, damaging lawns that are nitrogen deficient or soils that extremely dry.   McDonough lawn dollar spot disease is infected by a cob-web like thread, known as mycelia, that forms and then spreads mechanically by equipment, foot travel, animals, wind, or water.  On lower cut lawns in McDonough, symptoms of dollar spot disease present themselves as round, straw-colored, and somewhat sunken areas in the lawn approximately the size of a silver dollar, hence the name dollar spot disease.  On high cut lawns, spots may expand into patches exceeding 5 inches in diameter with same coloring characteristics.  During early morning times or in conditions of high humidity, the white cottony mycelia can be seen on infected patches in the lawn.  Our technicians at Nature’s Turf, Inc. are always inspecting our client’s lawns for Dollar Spot Lawn Disease as part of our McDonough Lawn Care Program.
