Abstract

In 2004–2006 there were studies on fungi colonizing and damaging different plant parts conducted. They were performed on productive plantations of peppermint (Mentha piperita L.) grouped in South-Eastern Poland. Fungi were isolated from superficially disinfected roots, rhizomes, stem bases and leaves by means of a mineral medium. Fungi from Fusarium spp. including F. avenaceum, F. equiseti, F. culmorum, F. oxysporum were obtained in the greatest number from roots showing necrotic symptoms. The Phoma strasseri was commonly isolated from rhizomes and stem bases with symptoms of necrosis and tissue disintegration. Altenaria alternata was isolated from leaves showing symptoms of necrotic, irregular spots.
