(2014-07)Two hundred and thirty-five faecal samples from adult and young captive vicuñas from the Abra Pampa Experimental Station of the National Agricultural Technology Institute (Jujuy Province, Argentina) were obtained in May ... -
Decrease in the incidence of charcoal root rot in common bean (Phaseolus vulgaris L.) by Bacillus amyloliquefaciens B14, a strain with PGPR properties
(2017-10)The objective of this study was to isolate strains of the genus Bacillus from different productive soils of the province of Salta, Argentina, which have growth promoting properties in common bean (Phaseolus vulgaris L.) ... -
Biological activity of the lipopeptide-producing Bacillus amyloliquefaciens PGPBacCA1 on common bean Phaseolus vulgaris L. pathogens
(2017-02)Bacillus amyloliquefaciens PGPBacCA1 was studied regarding its aptitude to protect common bean seeds from their intrinsic pathogens. Also, the inhibition of different environmental phytopathogenic fungi was tested. Two ... -
Lost forever? Ecosystem functional changes occurring after agricultural abandonment and forest recovery in the semiarid Chaco forests
(2018-09)Semiarid forests are worldwide threatened by land use changes, particularly agriculture. However, in some cases, due to particular economic or social processes, agriculture ends and forests may or may not recover to their ... -
Molecular identification and pathogenicity of Rhizoctonia spp. from tobacco growing areas in northwestern Argentina
(2015-06)In Argentina, more than 60 % of the tobacco crops are grown in the northwestern part of the country and where Rhizoctonia solani leads to a reduction in crop yield and quality. In this study, 35 isolates of Rhizoctonia ... -
Influence of a tropical grass (Brachiaria brizantha cv. Mulato) as cover crop on soil biochemical properties in a degraded agricultural soil
(Elsevier, 2017-11)The inclusion of tropical grass forage as a cover crop (CC) could be a useful tool to improve microbiological activity and, consequently, soil quality. The aim of this study was to evaluate the effect of Brachiaria brizantha ... -
Genetic characterization and pathogenicity of Rhizoctonia solani associated with common bean web blight in the main bean growing area of Argentina
(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 ... -
Participatory, multi-criteria evaluation methods as a means to increase the legitimacy and sustainability of land use planning processes. The case of the Chaco Region in Salta, Argentina
(2017-02)Conflicts over land use and ownership are common in South America and generate frequent confrontations among indigenous peoples, small-scale farmers, and large-scale agricultural producers. We argue in this paper that an ... -
Molecular identification and pathogenicity of 'Rhizoctonia' spp. recovered from seed and soil samples of the main bean growing area of Argentina
(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 ... -
Relationship between microbial functions and community structure following agricultural intensification in South American Chaco
(Czech Academy of Agricultural Sciences, 2016-07)Intensification of agricultural systems through the use of intensive agriculture and the advance of deforestation have led to a decrease of soil biological quality. Soil functional and structural microbiota are sensitive ... -
