A streak through history: Solving the riddle of chlorotic streak disease of sugarcane

Plant Pathology, Volume 73, Issue 1, Page 3-11, January 2024.
This review spans the 90 years that passed between the emergence of chlorotic streak disease of sugarcane and the discovery of its pathogen in 2018, and provides epidemiological information on the disease and its management. Abstract Until recently, the identity of the pathogen of chlorotic streak disease (CSD) was one of the most enduring mysteries of

First Report of Orange Rust Caused by Puccinia kuehnii in Sugarcane in Louisiana

Plant Disease, 2013
In June 2012, lesions typical of rust were observed on sugarcane cultivar Ho 05-961 (a complex hybrid of Saccharum L. spp.) on a farm near Schriever, Louisiana. Incidence and severity of disease symptoms were low. Two types of pustules were observed on leaves of the infected plants.

First Report of Puccinia kuehnii, Causal Agent of Orange Rust of Sugarcane, in Guatemala

Plant Disease, 2008
In September 2007 at Masagua, Escuintla Department, Guatemala, uredial lesions that appeared different from those of brown rust were observed on a sugarcane (a complex hybrid of Saccharum L. species) cultivar (CP 72-2086) considered resistant to brown rust caused by Puccinia melanocephala Syd. & P. Syd. Samples were sent to the USDA-ARS Systematic

Protocol for selecting orange rust resistant sugarcane cultivars by artificial inoculation in greenhouse

Biotecnología Vegetal, 2017
Orange rust [Puccinia kuehnii (W. Kruger) E. J. Butler] from sugarcane (Saccharum spp.) is a disease of potential importance for Cuban sugarcane farming. However, under natural conditions, the presence of symptoms has not maintained stability in the foci

Morphological changes of the Urediniospore of Puccinia kuehnii germ tube in function of temperature

Agronomy Science and Biotechnology, 2017
The aim of this study was to evaluate changes in the morfology and length of the germ tube of Puccinia kuehnii, under the influence of temperature and incubation time. The development of the germ tube was asssesed for 24 hours. The concentration of uredospores was 2x105 esporos.ml-1 calibrated by a Neubauer chamber and plated in a 0.1 ml aliquot in ...

First Report of Orange Rust of Sugarcane Caused by Puccinia kuehnii in Ivory Coast and Cameroon

Plant Disease, 2011
Orange rust of sugarcane caused by Puccinia kuehnii was detected in Florida in 2007 (1). It was hypothesized that the pathogen originated from Africa because brown rust of sugarcane (synonym common rust) was introduced to the Western Hemisphere from Africa (3).
