Mycoflora as a limitlng factor for pathogenic fungi in red clover pure cultures and its mixtures with cocksfoot

Compositions of fungi communities in soil, rhizosphere, rhizoplane and roots of red clover and cocksfoot were analysed. All the changes occuring daring four-years, cultivation under mountain conditions were investigated. The effect of saprophytic fungi present in the analysed communitics on chosen red clover pathogens: <i>Fusarium oxysporum</i> f. sp. <i>trifolii</i> and <i>Sclerotinia trifoliorum</i> was also studied.

Effect of fungal communities from the environment of culture of Trifolium pratense L. Dactylis glomerata L. on fungi pathogennic for clover.

Thebiotic function of communities of saprophytic fungi in the soil, rhizosphere, planospohere and roots of clover, orchard grass and their mixed cultures in respect to selected pathogenes of clover was examined. The pathogens were <i>Fusarium oxysporum</i> f. sp. <i>trifolii</i> and <i>Sclerotinia trifoliorum</i>. These communities were not able to resist <i>Fusarium oxysporum</i> f. sp. <i>trifolii</i>. However, most of the components of these communities limited the development of <i>Sclerotinia trifoliorum</i>.
