The study aims at selecting ecological approaches to protect barley from phytopathogenic fungi B. sorokiniana, D. graminea and D. Teres. Studies on barley revealed necrotic lesions 0.6–1.4 cm long with a dark brown or greyish centre on stems and a light brown or reddish outer zone on young leaves caused by B. sorokiniana isolates. Symptoms caused by D. teres ranged from necrotic spots to small spots up to 5.5–6 mm in size, but the number of lesions and degree of chlorosis was clearly more expressed on barley leaves than the stem. The detached D. graminea leaf analysis revealed large reddish-brown lesions spreading from the inoculation site to the top and lower part of the barley leaf segments. The practical value of the results obtained is the possibility of using them on agricultural land for growing cereals in order to minimise the damage caused by plant pathogenic fungi.
