FLORES, C.; SAN MARTIN, S.; CARRILLO, L.  y  BEJARANO, N.. Fusarium species of the Quebrada de Lozano, Jujuy, Argentina. Rev. argent. microbiol. [online]. 2005, vol.37, n.2, pp.109-112. ISSN 0325-7541.

A soil sampling was made in 50 cultivated places with horticultural and floral species where there were fusariosis records. For the isolation Bengal rose agar, peptone dichloran chloramphenicol agar and cayote dichloran chloramphenicol agar were used, being this last one, the more convenient. The isolates were identified as F. acuminatum, F. avenaceum, F. graminearum, F. merismoides, F. oxysporum, F. poae, F. proliferatum, F. semitectum, F. solani, F. subglutinans and F. sporotrichioides. It was proven the pathogenesis of F. acuminatum and F. proliferatum strains isolated from cultivated places with Cucurbita ficifolia and Vicia faba respectively, and of the strains of F. oxysporum obtained of soils with cultivations of Chrysanthemum leucanthemum, Ocimum basilicum and Zea mays. The F. merismoides, F. semitectum and F. subglutinans strains coming from places with these three vegetable species, were recovered as secondary invaders.
