Gray leaf spot (GLS) is a foliar fungal disease that affects grasses. In grasses other than maize it is caused by Pyricularia grisea , which only infects perennial ryegrass , tall fescue , and St. Augustine grass in places with warm and rainy climates.
St. Augustine is a dark green grass with broad, flat blades. It spreads by aboveground stolons , commonly known as "runners", and forms a dense layer. The grass occurs on both sides of the Atlantic Ocean , [ 1 ] including much of the southeastern United States, Texas, [ 2 ] [ 3 ] Mexico, and Central and South America. [ 1 ]

The disease most commonly associated with the panicum mosaic virus pathogen is St. Augustine Decline Syndrome, which infects species of turf grass and causes chlorotic mottling. [2] In addition to St. Augustine Decline, panicum mosaic virus is responsible for chlorotic streaking and mild green mosaicking in select cultivars of switchgrass and ...
They can cause plant disease and can infect a broad range of hosts in several monocot and dicot plant families. [3] Smuts are cereal and crop pathogens that most notably affect members of the grass family and sedges . Economically important hosts include maize, barley, wheat, oats, sugarcane, and forage grasses.
They are popular because of their fine texture, soft feel, and low growth habit. They can form dense mats and even mounds that grow over low features. In contrast to St. Augustine grass, they generally require less fertilization and are less vulnerable to insect and fungus damage, depending on environmental conditions. Zoysia is a native of ...
