A continuous improvement approach in the production of sugarcane vitroplants at the EEAOC
Last Updated: junio 11, 2025The Vitroplants Project of Estación Experimental Agroindustrial Obispo Colombres (EEAOC) began in 2001 and supplies high-quality “seed cane” (healthy, vigorous and with guaranteed genetic identity) to the farming sector. This is achieved with several biotechnological tools, including hydrothermotherapy, micropropagation and different molecular techniques
A Guide to Sugarcane Diseases: New Edition
Last Updated: junio 11, 2025The book A guide to sugarcane diseases was published in 2000 by ISSCT and Cirad, with the objective of gathering practical and updated information in sugarcane pathology. During the last two decades, new diseases have developed and were described in several countries.
Assessment of brown rust and smut resistance trials for rating Cuban commercial sugarcane cultivars
Last Updated: junio 11, 2025The sugarcane breeding program in Cuba evaluates new cultivars to determine their resistance to brown rust, smut, leaf scald, sugarcane mosaic, and red rot. In these trials, with high inoculum pressure, a set of control cultivars of known resistance are included to compare and assign a rating that describes the suitability of the new clone for commercial production.
Cryo- and osmo-therapy to eliminate viruses from infected sugarcane
Last Updated: junio 11, 2025Virus elimination via cryo- or osmo-therapy has only been recently reported for sugarcane mosaic virus (SCMV). Cryotherapy offers the dual advantage of germplasm conservation and virus removal while osmotherapy (osmotic treatments without liquid nitrogen) is a suitable alternative treatment for those cultivars that do not recover well after cryo-treatment.
Current status of sugarcane smut in Tucumán, Argentina – evaluation of genetic resistance and fungicide applications as control strategies
Last Updated: junio 11, 2025Under a changing climate, sugarcane smut (Sporisorium scitamineum) has emerged as a significant threat in Tucumán, Argentina, since 2020. The distribution and intensity of smut across Tucumán sugarcane fields was determined and alternative control strategies for the disease analyzed.
Development of a real-time singleplex and multiplex PCR diagnostic assay for detecting sugarcane pathogens and optimization of nucleic acid extraction methods
Last Updated: junio 11, 2025Systemic sugarcane diseases were silently introduced to new areas due to the lack of appropriate and specific detection methods. Two bacterial diseases are the focus of the Sugarcane Disease Detection Lab (SDDL) in Louisiana – ratoon stunt disease (RSD), caused by Leifsonia xyli subsp. xyli, and leaf scald (LS), caused by Xanthomonas albilineans.
Development of internal transcribed spacer based molecular markers to identify Colletotrichum falcatum causing sugarcane red rot
Last Updated: junio 11, 2025Red rot, caused by Colletotrichum falcatum, is one of the most devastating fungal diseases of sugarcane occurring in Pakistan and is often referred to as “sugarcane cancer”. The pathogen, C. falcatum, shows significant variability, leading to the breakdown of resistance in many sugarcane varieties.
EEAOC Vitroplants Project: the importance of phytosanitary diagnosis and its impact on the health status of commercial sugarcane fields in Tucumán, Argentina
Last Updated: junio 11, 2025Most economically significant sugarcane diseases are transmitted by infected planting material during commercial propagation. The production of high-quality planting material and knowledge of crop sanitary conditions are key factors for designing disease-management strategies.
Effects of desert phyto-extracts on whip development in sugarcane smut
Last Updated: junio 11, 2025Sugarcane (Saccharum hybrids) is a major crop facing significant impacts from the development of smut whips caused by Sporisorium scitamineum. This disease can severely impact both the quantity and quality of sugarcane, making effective disease management crucial for sustaining production and economic stability for growers.
Genome-wide association analysis for the identification of SNPs related to resistance to orange rust, Puccinia kuehnii
Last Updated: junio 11, 2025Orange rust, caused by Puccinia kuehnii, is a significant disease affecting sugarcane production in many countries worldwide. Variation in disease susceptibility among commercial varieties highlights the need for genetic resistance as a primary strategy for disease control.
