The Rhizoctonia solani fungus attacks zoysia grass and causes a disorder called large brown patch. Small, rounded spots of discolored, water-soaked grass appear on zoysia lawns.These damaged areas often have a yellowish ring of dying grass around their perimeters.oysia is a species of warm-weather grass native to Southeast Asia. Named after Karl von Zois, an 18th-century botanist from Austria, zoysia became popular with United States homeowners in the 1940s and 1950s, particularly in the southern United States, because these grasses perform well in warm climates.
