Rhizoctonia Diseases
A range of fungal diseases which affect warm season, as well as cool season turfgrasses. The main cool season disease is Brown Patch; whilst for warm season turfgrasses, especially Zoysia Grasses, and besides R. solani (which can have the common name of Large Patch for some warm season attacks), other Rhizoctonia species can be a problem: Leaf Spot (R. zeae); Sheath Spot (R. oryzae) and Yellow Patch (R. cerealis).
