The object of the research work were an isolate of Colletotrichum gloeosporioides causing anthracnose on Hypericum perforatum L. (St. John’s Wort) as well as three fungicides belonging to different chemical groups: Sarfun 500 SC, Amistar 250 SC and Gwarant 500 SC. The studies on the inhibiting mycelium growth effect were carried out in vitro on the media amended with the fungicides at concentrations corresponding to field recommended doses for control of anthracnose of many vegetables and ornamental plants and additionally in values double increased and decreased them. The results showed that Sarfun 500 SC even at the twice reduced dose (0.05%) concentration was most effective against this pathogen. Amistar 250 SC at the lower concentration (0.05%) demonstrated low antifungal activity but the effect of 0.1% concentration was significantly higher. In the case of the fungicide Gwarant 500 SC the effective concentration was 0.4% whereas recommended dose is 0.2%. The Sarfun 500 SC and Amistar 250 SC can be therefore regarded as a prospective means of limiting growth and development of Colletotrichum gloeosporioides and protecting St. John’s Wort from this pathogen.
