Online published on 31 October, 2013. Abstract Infected samples of leaves and buds of linseed were brought to the laboratory for isolation and identification of pathogen as Alternaria lini. In pathogenicity test most common symptoms of this disease were leaf spot and black bud. Affected buds in most of the cases were completely replaced by fungal mycelium and conidia. Among environmental factors, in our findings the suitable temperature for the growth and sporulation of Alternaria lini was 25ÚC. The influence of pH maximum growth and sporulation was observed at pH of 6.5. We examine the best media for growth and sporulation of Alternaria lini was Potato dextrose agar followed by Oat meal and Richard's agar media.
