Leaf Spot & Melting Out

Leaf spot and melting out diseases occur in lawns that are stressed from excessive water and a very short mowing height. The diseases are caused by two separate fungi, but because the diseases often occur together, they’re considered a single disease complex.

Leaf spot symptoms include small, purple-to-black spots on individual leaf blades. The spots become elliptical in shape and may be surrounded by a purple border. Tissue in the center of the spot may die and turn a beige or straw color. If a spot extends across the leaf, the blades wither   and die.

Melting out is the more serious of the two diseases. Initially, its symptoms are similar to those of leaf spot. But as the disease progresses, the fungus works its way to a plant’s base and attacks the crown and roots. Affected turf appears yellowish, thin and shabby with irregular patches of dead grass. When these areas are raked, dead grass plants are easily removed.

Fungicide treatments are needed to control the leaf spot/melting out disease complex. Remember, chemicals are most effective when they’re used in conjunction with proper lawn-care practices.
