ABSTRACT

The study examined the effect of 17 fungi species obtained from the leaves and stems of St. John’s wort (Hypericum performatum L.) on the growth of Seimatosporium hypericinum. The fungi that strongest limited the growth and sporulation of S.hypericinum included Trichoderma spp. and Gliocladium roseum. The studied species from the genus of Trichoderma caused complete death colonies and conidiospores of the pathogen as early as after 5-12 days, while G.roseum after 34 days of common growth. The growth of S.hypericinum was also inhibited by the fast growing species from the genera of Fusarium and Botrytis cinerea, Rhizoctonia solani and Phoma exigua var. exigua. With its common growth with C.gloesporioides and P.janthinellum, the pathogen formed an inhibition zone of 1-2 mm.

Key words: antagonistic fungi, Seimatosporium hypericinum..
