Technical Abstract: Sugarcane orange rust, caused by Puccinia kuehnii, was first detected in Florida in 2007, the first for Western Hemisphere. Subsequently, it has spread to the majority of sugarcane producing countries in the hemisphere. Orange rust is distinguished from brown rust its pustule size which is slightly smaller and more elongate, its orange color and urediospores that have an apical thickening in contrast to darker urediospores of the brown rust pathogen, Puccinia melanocephala that are uniform in wall thickness. Orange rust has caused economic losses and has required fungicidal control in susceptible cultivars. (Manuscript published in Spanish)
