Field experiments were carried out at Mochełek (17°51’E, 53°13’N). The health status of roots and stem bases of oat cultivated in pure stand and in mixture with spring rye was evaluated. A low intensity of root-rot was observed. Eyespot and Fusarium foot rot were observed on stem bases. Oat was infected with Fusarium  spp. in higher degree when it was grown in mixture with spring rye. The pathogenic fungi occurring on oat roots were mostly represented by Fusarium spp., especially F. solani and F. equiseti. Stem bases showed the occurrence of F. culmorum, F. equiseti and F. avenaceum. Cultivation of oat in mixture did not affect the composition of fungal species occurring on roots and stem bases.
