Leaf Spot and Melting Out of Turf

Leaf spot and melting out are two different turf diseases that have similar symptoms. They both primarily affect Kentucky bluegrass, perennial ryegrass, and tall fescue. They occur in the cooler spring and late summer months. These diseases are most active on stressed or poorly managed turf. The best way to control these diseases is to manage turf properly and use cultural practices that help prevent their establishment. Fungicides may be used early in the season as a preventive measure.
