Brown Patch Disease


Brown Patch Disease is a turf fungal disease that creates brown circles in lawns which will quickly spread if left untreated. Brown Patch begins as a small circle, or several small circles a couple of inches in diameter, the small circles will continue to grow in size up to a few feet in diameter over many months. Often the inner circle can begin to repair itself even though the circles keep spreading. This is because the active part of the fungal disease in Brown Patch is always at the outer edge of the circle. This often leads to an appearance of rings on the outside of the circles.
