Abstract/Contents:"Diseases induced in warm season grasses by Rhizoctonia species include large patch, yellow patch, and Rhizoctonia leaf and sheath spot. They differ in symptomology, conducive weather conditions, and causal agents. Large patch occurs in zoysiagrass and other warm season grasses. Causal agents have been determined to be R. solani, AG 2,2 'LP'. Typically, 0.5 to 30 meter patches are present in spring after green up, and sometimes in fall prior to dormancy. Infected shoots at patch margins exhibit a basal rot, with brown lesions that may girdle the shoots. Affected shoots are brown, tan, or yellow in appearance. Yellow patch, caused by R. cerealis, occurs primarily in zoysiagrass. Patches up to 0.3 meters occur in the fall of the year prior to dormancy. Leaf lesions resemble dollar spot, with distinct margins, and tan centers. Rhizoctonia leaf and sheath spot, caused by R. zeae or R. oryzae, occurs in hot, humid environments. Symptoms include yellow rings of affected turf with lesions on leaf blades and sheaths. Lesions typically are light brown, with a faint border. Binucleate Rhizoctonia species also are frequently isolated from warm season grasses."
