In the conducted researches fodder plants growing in the conditions of Azerbaijan were analyzed according to the fungal biota. It was found that 110 species of fungi are involved in the formation of the mycobiota of fodder plants, and 74.5% of the total mycobiota belong to Ascomycota, 18.2% to Basidiomycota and 7.3% to Zygomycetes (Mucormycota). According to the specific weight of phytopathogens, Artemisia vulgaris and Medicago sativa differ from other plants, and in this case, the difference is manifested by the fact that the specific weight of phytopathogens in A. vulgaris is the lowest in the total mycobiota, and M. sativa is the highest. It became clear that 70 species of these fungi belong to phytopathogens, of which 37.1% has specific characteristics of necrotrophic, 35.7% of biotrophs, and 27.1% of hemibiotrophs.
