Technical Abstract: Orange rust is caused by a basidiomycetus fungus, Puccinia kuehnii, Butler. The initial symptoms of orange rust are minute, elongated yellow spots, which take on a pale yellow-green halo as they increase in size. P. kuehnii has been reported to infect Saccharum spontaneum, S. officinarum, S. robustum, S. edule, commercial hybrid varieties, Erianthus arundinaceus, and Sclerostachya fuscum. Orange rust is spread by wind and rain splash, causes severe yield losses in susceptible varieties, and is mainly controlled by cultivating resistant varieties. Chemical control is also available.
