In June 2007, rust symptoms were observed on sugarcane cultivar CP80-1743 about six miles east of Belle Glade, Florida. The disease was confirmed as orange rust of sugarcane. It is hypothesized that rust spores were blown into the region as a disperse spore cloud from an unknown source rather than spread from a single or several small focal points. This 3-page fact sheet was written by P. Rott, S. Sood, J. C. Comstock, R. N. Raid, N. C. Glynn, R. A. Gilbert, and H. S. Sandhu, and published by the UF Department of Agronomy, June 2014.
