|Area thinned by Grey Leaf Spot|
These past few weeks we have been challenged in some fairway areas and rough with a turf disease known as grey leaf spot. Grey leaf spot, or gls, primarily attacks perennial ryegrasses and tall fescue. It’s a fast acting disease, spreads easily, and can blight large areas of turf in a matter of a day or two from the time of the first infection. It is a hard disease to detect, and is usually only recognized after the damage is done. The telltale sign that it is or was gls are dead rye grass leaves twisted up like a corkscrew.
