Changes in microbial and physicochemical properties under cover crop inclusion in a degraded common bean monoculture system
Aban, Carla Luciana; Perez Brandan, Carolina; Verdenelli, Romina Aylen; Huidobro, Dina Jorgelina; Meriles, José Manuel; Vargas Gil, Silvina (Elsevier, 2021-12)The expansion of the common bean monoculture system along with intensive agricultural practices focused on productivity has generated a misuse of natural resources, accompanied by a significant decline of the soil ecosystem ... -
Genetic characterization and pathogenicity of Rhizoctonia solani associated with common bean web blight in the main bean growing area of Argentina
Spedaletti, Yamila Andrea; Aparicio Gonzalez, Monica Alicia; Mercado Cardenas, Guadalupe Eugenia; Rodriguero, Marcela Silvina; Taboada, Gisel María; Aban, Carla Luciana; Sühring, Silvia Susana; Vizgarra, Oscar N.; Galvan, Marta Zulema (2016-12)Common bean web blight (WB), caused by the fungus Rhizoctonia solani (teleomorph Thanatephorus cucumeris), is among the endemic fungal diseases of major impact in north‐western Argentina (NWA). This study aimed to analyse ... -
Intensificación agrícola sustentable: efectos a largo plazo sobre propiedades químicas, actividad enzimática y comunidad microbiana
Maury, Mariana; Gabbarini, Luciano; Conde, María Belén; Aban, Carla Luciana; Lorenzon, Claudio Antonio; Ortiz, Jimena; Pegoraro, Vanesa Romina; Pereyra, Luciano Alberto; Velez, Georgina; Seravalle, Ruben Dario; Marelli, Patricio Martin; Salvagiotti, Fernando; Bacigaluppo, Silvina; Faggioli, Valeria Soledad (Asociación Argentina de la Ciencia del Suelo, 2022-11-15)Las prácticas de intensificación agrícola sustentable (IA) buscan aumentar la producción conservando los recursos utilizados. Debido a que la salud del suelo depende en gran medida de los microorganismos del suelo y estos ... -
Molecular identification and pathogenicity of 'Rhizoctonia' spp. recovered from seed and soil samples of the main bean growing area of Argentina
Spedaletti, Yamila Andrea; Mercado Cardenas, Guadalupe Eugenia; Taboada, Gisel María; Aban, Carla Luciana; Aparicio Gonzalez, Monica Alicia; Rodriguero, Marcela Silvina; Vizgarra, Oscar N.; Sühring, Silvia Susana; Galindez, Guadalupe; Galvan, Marta Zulema (2017-08)The objective of this study was to perform the molecular and pathogenic characterization of Rhizoctonia solani in bean seed and soil samples from fields with root rot symptoms in northwestern Argentina. Fifty-two Rhizoctonia ... -
Molecular, morphological and pathogenic diversity of Sclerotinia sclerotiorum isolates from common bean (Phaseolus vulgaris) fields in Argentina
Aban, Carla Luciana; Taboada, Gisel María; Spedaletti, Yamila Andrea; Aparicio, Maria Cecilia; Curti, Ramiro Nestor; Casalderrey, Norma Beatriz; Maggio, Maria Elisa; Chocobar, Mario Osvaldo; Salgado, M.; Galvan, Marta Zulema (2018)White mould, caused by Sclerotinia sclerotiorum, is one of the most threatening fungal diseases occurring across major bean production regions worldwide. In Argentina, under favourable weather conditions, up to 100% seed ... -
Population structure of the fungus Sclerotinia sclerotiorum in common bean fields of Argentina
Aban, Carla Luciana; Taboada, Gisel María; Spedaleti, Yamila Andrea; Maita, Efraín; Galvan, Marta Zulema (Springer, 2021-05)S. sclerotiorum is the causal agent of the white mould disease on common bean crops, one of the most threatening fungal diseases occurring across major bean production regions. Currently, there are no commercial cultivars ... -
Service crops improve a degraded monoculture system by changing common bean rhizospheric soil microbiota and reducing soil-borne fungal diseases
Aban, Carla Luciana; Verdenelli, Romina Aylén; Vargas Gil, Silvina; Huidobro, Dina Jorgelina; Meriles, José Manuel; Perez Brandan, Carolina (Oxford University Press, 2021-02)Intensive agricultural practices have resulted in progressive soil degradation, with consequences on soil ecosystem services. The inclusion of service crops is a promising alternative to support the sustainability of the ... -
Short-term service crops affect the spatial organization of soil aggregates, microbial C–N biomass, and microbial activities in a degraded monoculture system
Ducci, María Antonella; Aban, Carla Luciana; Huidobro, Dina Jorgelina; Vargas Gil, Silvina; Acreche, Martin Moises; Perez Brandan, Carolina (Elsevier, 2024-07)Service crops are grown to provide ecosystem services, such as the ability to increase soil organic matter and fertility. Also, they reduce erosion processes, weed control, disease regulation, water purification, soil ... -
Soil Properties and Bacterial Communities Associated with the Rhizosphere of the Common Bean after Using Brachiaria brizantha as a Service Crop: A 10-Year Field Experiment
Aban, Carla Luciana; Larama, Giovanni; Ducci, María Antonella; Huidobro, Dina Jorgelina; Abanto, Michel; Vargas Gil, Silvina; Perez Brandan, Carolina (MDPI, 2023-01)Intensive agricultural farming practices, such as monoculture, require long bare fallow periods and the overuse of agrochemicals, which compromise soil health over time. Increasing plant diversity in agroecosystems with ...
