Characteristics of a Rust Fungus
Types
- Almost 100,000 different types of plant rust fungi are in existence throughout the world. This makes rust-causing fungi the most diverse group of parasitic plants that have a wider host range than any other. This is also because the majority of rust fungi are host specific where they only attack certain kinds of plants. For instance, Puccinia graminis causes stem rust on wheat, Puccinia pelargonii-zonalis causes geranium rust, chrysanthemum white rust is caused by Puccinia horiana and Phragmidium mucronatum causes rust on roses.
