Rust caused by Puccinia melanocephala was discovered on sugarcane (Saccharum spp.) on the Hawaiian island of Kauai on 17 February 1982 and subsequently was found on Oahu, Maui, and Hawaii. Because none of the major commercial sugarcane clones are susceptible to this rust, no significant yield losses are expected.
