How to Identify Dollar Spot
Dollar spot causes sunken, circular patches that measure up to two inches in diameter on golf greens and several inches on higher mown turf. The patches turn from brown to straw colored and may eventually increase in size forming irregularly shaped areas. Dollar spot is favored by temperatures between 59 degrees to 86 degrees and continuously high humidity. This disease is often found in climates with warm days, cool nights and intense dews.
