Leaf Spot (Lawns)

Leaf Spot (Lawns)

This condition causes patches of thin, brown grass; the blades have small oval spots with bright red centers and darker borders. Most common on bluegrass and rye grass, leaf spot is caused by various fungi (some formerly known as helminthosporia leaf spot fungi). Use a fungicide when you first notice damage. Too-lush lawns and those under stress from excessive water or fertilizer, short mowing, and thatch are most susceptible.
