Root rot poses a serious threat to the main fruit crop domestic apple in nurseries and young orchards. Obtaining healthy planting material, free from root pathogens and root rot, is an especially priority task in conditions of intensive production. In the process of analyzing the affected plants from nurseries and young orchards at four sampling points, pathogens of apple root rot from 11 genera were identified and 431 isolates were extracted. The most common causative agents of apple root rot seedlings in the entire studied sample were species of the genus  Fusarium  spp. Soil micromycetes such as  Rhizoctonia  spp.,  Cladosporium  spp.,  Cylinrocarpon  spp., and oomycetes from the genus  Pythium  were rare. The composition and occurrence of species were heterogeneous at different points in the studied region.  Phomopsis mali  (Schulzer &amp; Sacc.) Died.,  Cytospora  spp.,  Alternaria alternate  (Fr.) Keissl., and  Aspergillus niger  Tiegh. have been associated with root rot of seedlings and young apple trees.
