| Abstract: | Barley is an important malting crop extensively cultivated in the province of Buenos Aires (AR). In 1992, an unusual disease was detected with a prevalence of 8% on 36 commercial fields examined in this province. The pattern of the disease, the characteristics of the pathogen and the test for pathogenicity indicated that the causal agent was Pseudoseptoria donacis. |
