The pathogen was isolated from wheat leaves growing under field conditions, cultured on PDA and identified by its morphobiometric and cultural characters. The disease symptoms and morphological characters of the pathogen are described. Pathogenicity of the isolate was confirmed by inoculating ten wheat cultivars under greenhouse conditions.   Key words: Phoma sorghina, wheat, Argentina
