Abstract
The study determined the antagonistic effect of microorganisms of the soil environment of salsify towards the following pathogenic fungi: A. alternata, F. culmorum, F. oxysporum, R. solani and S. sclerotiorum. The field experiment considered mulching the soil with such cover crops as oats, phacelia and common vetch. Laboratory tests pointed to oats as the plant which has the best influence on the quantity of antagonistic Bacillus spp., Pseudomonas spp., Gliocladium spp., Penicillium spp. and Trichoderma spp. These microorganisms reduced the growth of A. alternata and F. culmorum in the most effective way. Antagonistic fungi inhibited the growth of F. oxysporum, R. solani and S. sclerotiorum in a greater degree than antagonistic bacteria. Mulching the soil with cover crops can reduce the growth and development of soil-borne fungi pathogenic to salsify.
