Technical Abstract: Sugarcane orange rust, caused by Puccinia kuehnii, was observed in Florida (first time in the Western Hemisphere) in June 2007. The symptoms are orange pustules that are lighter than the brown rust pustules and the spores are also orange brown in color. The major cultivar, CP 80-1743 at that time was susceptible and had severe symptoms. Other commercial cultivars were resistant but their disease reaction changed over time and some are now susceptible. Resistance is the preferred means of control. However, fungicides can reduce rust severity and have been used to control the disease.
