Record of Sugarcane Orange Rust in the Lowland Tropics of Santa Cruz, Bolivia

Abstract

Sugarcane is an important crop in the eastern region of Bolivia. Rusts are one of the main diseases that affect this crop. At Latin American level reports are known about the emergence of the new rust known as orange rust. In July 2017, samplings of leaves with apparent symptoms of orange rust were carried out in production fields in the Saavedra and Mineros municipalities of the Santa Cruz department. After analysing in the laboratory, it was recorded that uredinias, urediospores, telias and teliospores correspond to Puccinia kuehnii E. J. Butler causal agent of sugarcane orange rust. This is the first record of the orange rust in Bolivia.
