Stolone-born fungi are one of the most important causes of decrease of the yield in the cultivation of peppermint. From this reason, the aim of our studies was isolation and determination of pathogenic microorganisms from mint stolones. Stolones of introduced cultivar Mitcham were analyzed. Among seven species of microorganisms determined, the most important are species belonging to the genus Fusarium and Verticillium. In samples, collected from the experimental field of Institute for Medicinal Plant Research located in the neighborhood of Pančevo, following species were isolated and determined.

Fusarium equiseti (Corda) Sacc.
Fusarium culnorum (W.G. Smith) Sacc.
Fusarim semitectum Berk & Rav.,
Fusarim subglutinas Wr. Reink.
Verticillium lateritum Fr.
Verticillium dahliae Kleb.
Penicillum spp.
Trichoteciun roseum Link &Fries.
Alternaria spp. Results of our investigations confirmed that mint stolones are populated with pathogen type micro-organisms‚ as well as those of saprophyte nature. Fungi of the genus Verticillium and Fusarium causes specific chloroses and necroses characteristic for these phytopathogens.

Key words: mint, micro-organisms, fungi, pathogens, Fusarium, Verticillium.
