The recent weather has been warm and moist, perfect conditions for disease development. We have been applying fungicides to our greens and tees almost weekly. There are numerous diseases that we keep a close watch for and most behave differently. Turf diseases are funguses that produce spores that spread by wind, water, and mechanically (mowers.) In moist conditions, spores germinate and grow by producing hyphae. A mass of hyphae is known as mycelium, which is seen in the photo below. This photo was taken in the rough which only gets a fungicide application once a month.
