Abstract: The present studies determined the antagonistic activity of selected fungi of the soil environment of root chicory -a high-inulin plant, with considerable pro-health values - towards such fungi pathogenic towards this plant as: Altenaria alternata, Botrytis cinerea, Fusarium culmorum, F. oxysporum, Thanatephorus cucumeris and Sclerotinia sclerotiorum. The cultivation of root chicory took into consideration soil mulching with cover crops (oats, tansy phacelia and common vetch) as well as the conventional cultivation, i.e. without any cover crops. The total population of fungi after soil mulching with common vetch was almost twice as small as in the control and smaller than with phacelia as a cover plant. Antagonistic Clonostachys spp., Myrothecium spp., Penicillium spp. and Trichoderma spp. displayed differentiated activity towards the studied fungi. The greatest antagonistic effect was observed after the mulch of oats. Besides, oats and common vetch the most positive effect on the antagonistic activity was that of Clonostachys spp., Myrothecium spp., Penicillium spp. and Trichoderma spp. Those fungi were most effective in inhibiting the growth and development of F. oxysporum, T. cucumeris and S. sclerotiorum.
