Association mapping and localization of molecular markers linked to resistance in sugarcane to brown rust
Last Updated: junio 11, 2025Sugarcane brown rust (Puccinia melanocephala) is a disease of major importance in many sugar producing regions of the world, causing significant yield losses and economic impacts. The most effective method for controlling this disease is the use of resistant commercial varieties.
Automation of artificial photoperiod in the north of Argentina
Last Updated: junio 11, 2025The Sugarcane Breeding Program at Chacra Experimental Agrícola Santa Rosa conducts crosses using artificial flower induction. To enhance this process, we developed a new automated photoperiod control system. This system utilizes microcontrollers that send ON/OFF signals to light fixtures in the photoperiod chambers while receiving real-time sensor data.
Brix and stalk number associated with sugarcane productivity in different edaphoclimatic conditions in Brazil
Last Updated: junio 11, 2025Brix and stalk numbers associated with sugarcane productivity (Brix and number of stalks) were determined under different soil and climate conditions in Brazil using material from the early stages of the selection program of the Agronomic Institute of Campinas - IAC.
CRISPR/Cas9 mediated homology directed repair enables precise modification in sugarcane ALS gene
Last Updated: junio 11, 2025We investigated CRISPR/Cas9 homology-directed repair (HDR)-mediated introduction of the W574L mutation aimed at obtaining tolerance to acetolactate synthase (ALS) inhibiting herbicides. Specific sgRNAs were designed and inserted into Cas9-expressing gene editing vectors.
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.
Dynamics of Diatraea spp. and their parasitoids in Colombia: keys for pest management in sugarcane
Last Updated: junio 11, 2025Stemborers of the genus Diatraea are the main pests of sugarcane in the Cauca River Valley, Colombia, with four species of economic importance: D. saccharalis, D. indigenella, D. busckella, and D. tabernella. Monitoring these sugarcane borers up to 3.5 months into the crop cycle is essential to understand the dynamics of the pests and their parasitoids in this region. In this study, 6,506 fields were monitored in 2016, 2019, 2022, and 2023 to identify the changes in temporal and spatial distribution of Diatraea spp. populations, as well as the effectiveness of parasitoids.
Economic and environmental assessment of chlorantraniliprole and methoxyfenozide for the management of Diatraea saccharalis in sugarcane in Tucumán, ArgentinaEconomic and environmental assessment of chlorantraniliprole and methoxyfenozide for the management of Diatraea saccharalis in sugarcane in Tucumán, Argentina
Last Updated: junio 11, 2025The stemborer Diatraea saccharalis is the main pest of sugarcane in Argentina. Its control has evolved in recent years toward more effective and sustainable strategies.
