GARCIA-LEON, E et al. Diversidad e incidencia de hongos asociados a enfermedades foliares de la avena (Avena sativa L.) en los valles altos de México. RIA. Rev. investig. agropecu. [online]. 2015, vol.41, n.1, pp.53-56. ISSN 1669-2314.

The aim of this study was to determine the fungal species associated to foliar diseases on oat in the highlands of Mexico. During spring-fall seasons 2009 and 2010, a total of 815 samples of oat plants exhibiting foliar diseases were collected from 163 different oat fields. Fungal identification was based on morphological characteristics. Six different pathogenic fungal species were identified: Colletotrichum graminicola, Curvularia hawaiiensis, Drechslera avenacea, Passalora graminis, Puccina coronata, Puccinia graminis f. sp. avenae. Whereas, that the saprophytic and weakly pathogenic fungi founded were: Alternaria triticicola, A. triticina, A. uredinis, Curvularia protuberata y Pleospora sp. The species P. graminis f. sp. avenae (73%), P. coronata (61%) and D. avenacea (19%) were the pathogenic fungi most frequently founded.

Keywords : Alternaria; Colletotrichum; Curvularia; Drechslera; Puccinia.
