Sugarcane Rust in Hawaii. J. C. Comstock, Associate Plant Pathologist, Experiment Station, Hawaiian Sugar Plantersí Association, P.O. Box 1057, Aiea, Hawaii 96701. T. L. Tew, Head, Genetics & Pathology Department, and S. A. Ferreira, Associate Plant Pathologist, Experiment Station, Hawaiian Sugar Plantersí Association, P.O. Box 1057, Aiea, Hawaii 96701. Plant Dis. 66:1193-1194. Accepted for publication 2 August 1982. Copyright 1982 American Phytopathological Society. DOI: 10.1094/PD-66-1193.

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.
