During several years of research, pathogenic mycopopulation of the most important medicinal and aromatic plant species cultivated at the experimental field of the Institute for Medicinal Plant Research Dr Josif Pancic in Pancevo and in cooperative production in Banatsko Novo Selo, Indjija, Ruma, Gorobilje, Kacarevo, and Zrenjanin, was studied. Investigations covered following species: marshmallow (Althea officinalis), coneflower (Echinacea purpurea and Echinacea angustifolia), St. John wort (Hypericum perforatum) and garden sage (Salvia officinalis). From plants with different disease symptoms, over 200 isolates of plant pathogens were obtained. From that number, 166 of them were selected for further investigation. Mycopopulation of the tested plants consisted of a number of parasitic and saprophitic pathogens. In whole, 31 species of plant pathogenic fungi belonging to 20 taxa were determined. In isolations from these plant species, plant pathogenic fungi were more dominant on seeds of medicinal and aromatic plants and in lesser extent in roots and over-ground organs. Tests for the pathogenicity evaluation revealed that all isolates of Fusarium species and Sclerotinia sclerotiorum are pathogenic to their host plants in controlled conditions. For the first time Erysiphe cichoracearum was isolated from St. John wort, Oidium spp. was registered on garden sage and E. purpurea, then Phoma sp. on marshmallow and coneflower, as well as Sclerotinia sclerotiorum on E. purpurea and E. angustifolia. Fungi belonging to Fusarium genus were also recorded for the first time and determined to the species level. Pathogenicity of these important causal agents of different diseases in medicinal and aromatic plants was evaluated, too.
