Interpretive Summary:

Technical Abstract: Orange rust of sugarcane caused by Puccinia kuehnii was observed for the first time in the Rio Grande Valley of Texas in 2017. The identity of P. kuehnii was verified by PCR assays conducted independently in two laboratories. The disease was observed in variety trials at three sites in Hidalgo and Cameron Counties on 12 experimental clones and one commercial variety, CP 89-2143. In 2017, approximately 45% of the sugarcane production area in Texas was planted with cultivar CP 89-2143. Although orange rust was observed on CP 89-2143 in the variety trials, no orange rust was reported in commercial plantings of this cultivar. Incidence and severity of orange rust were greater in variety trials located in the eastern portion of the sugarcane production area of the Rio Grande Valley.
