The research followed the evolution of the mycosis attack of autumn barley cultivated in the classical culture and during the conversion period to switch to the ecological culture, in the agricultural year 2021-2022, in Tulcea county. The frequent micromycetes were Pyrenophora teres, Pyrenophora graminea, Puccinia hordei, Rhynchosporium secalis and Blumeria graminis f.sp. hordei. In the barley cultivated in the two systems, the incidence of attack by Pyrenophora teres and Puccinia hordei was 100%. The frequency of the Pyrenophora graminea attack was 5% and 6% in the control variants. The powdery mildew attack was more sensitive to barley in the conventional culture and the Rhynchosporium secalis attack was subunit in both culture systems. The application of the treatment in the conventional system ensured an effectiveness of over 64%.
