Dynamics of Diatraea spp. and their parasitoids in Colombia: keys for pest management in sugarcane
Last Updated: junio 19, 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, Argentina
Last Updated: junio 19, 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.
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 19, 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.
Effect of important weeds of sugarcane on the oviposition preference of Diatraea saccharalis
Last Updated: junio 19, 2025Diatraea saccharalis (Ds) is the most important pest of sugarcane (Saccharum hybrids) (So) in Tucumán, Argentina. Weeds are a threat to crop productivity and can act as alternative hosts for pests. Therefore, it is necessary to increase our understanding of Ds's preference for oviposition on So, Sorghum halepense (Sh), Urochloa platyphylla (Up), Sicyos polyacanthus (Sp), and Tithonia tubaeformis (Tt).
Effects of desert phyto-extracts on whip development in sugarcane smut
Last Updated: junio 19, 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.
Evaluation of brown and orange rust resistance genes in sugarcane through molecular markers
Last Updated: junio 19, 2025Molecular markers associated with resistance genes, such as Bru1 (brown rust) and G1 (orange rust), hold significant potential for predicting resistant genotypes during the selection phases of breeding programs. We aimed to correlate the phenotypic response with the genotypic profiles of Bru1 and G1 markers in a panel of 300 sugarcane accessions, which constitute the Brazilian Panel of Sugarcane Genotypes (BPSG). Among the evaluated accessions, 60.3% (181) exhibited field resistance to brown rust, of which 70.7% (128) carried the Bru1 gene.
Evaluation of freeze-damaged indicators in ‘TUC’ sugarcane varieties in Tucumán, Argentina
Last Updated: junio 19, 2025In Tucumán, Argentina’s primary sugarcane-producing province, frost events frequently affect optimal crop development, and sugar recovery during industrial processing. The entire sugarcane production area is prone to frost. Therefore, characterizing the TUC varieties (developed by the Sugarcane Breeding Program of the Estación Experimental Agroindustrial Obispo Colombres (SCBP-EEAOC)), in relation to frost-induced deterioration is crucial for optimizing cultivar management strategies.
Evolution of stemborer and wireworm management in Florida sugarcane
Last Updated: junio 19, 2025At least 14 arthropod species have been listed as pests of sugarcane in Florida, which is produced in the southern region of the state on 160,000 ha. Among these pests, stemborers (Lepidoptera: Crambidae) and wireworms (Coleoptera: Elateridae) are major concerns.
Field-based prediction of sugarcane photosynthesis through environmental inputs
Last Updated: junio 19, 2025Sugarcane (Saccharum hybrids) is a highly productive C4 crop prevalent in tropical and subtropical areas. However, its photosynthetic efficiency is influenced by environmental factors such as light, moisture and temperature. Understanding these interactions is critical for optimizing yields and addressing climate-related challenges.
Genetic and hormonal regulation of plant height in sugarcane: QTL mapping and functional insights into gibberellin-driven growth
Last Updated: junio 19, 2025Plant height is a critical agronomic trait influencing biomass accumulation, lodging resistance, and mechanized harvesting efficiency in sugarcane. However, the genetic and molecular mechanisms regulating height variation remain largely unexplored
