G92-1119 Rust Diseases of Turfgrass

This NebGuide describes the various rust diseases common to Nebraska and offers suggestions for maintaining a vigorous and disease-resistant lawn. Rust diseases occur on all turfgrasses; however, most rust problems occur on Kentucky bluegrass, perennial ryegrass, tall fescue and zoysia. In the cool-temperate regions of North America, cool season turfgrasses may suffer severe injury late in summer by attack from one of the rust pathogens. In addition, rust-weakened plants are much more susceptible to injury from environmental stresses and to attack by other turfgrass pathogens.
