We studied the antifungal activity of the  Bacillus subtilis  BZR 336g strain against the test culture of the fungus  Fusarium oxysporum var. orthoceras  App. et Wr. BZR 6, depending on the addition of citric acid crystalline hydrate, a microelements solution and corn extract to the liquid nutrient medium. It was found that citric acid at a concentration of 15 g/l improves the bioavailability of microelements and increases antifungal activity. Corn extract and microelements without the formation of a chelate form with citric acid do not affect the fungicidal properties of  B. subtilis  BZR 336g. However, the corn extract at a concentration of 3 g / l increases the titer of bacteria in the liquid culture from 2 ± 0.1 × 10 8  to 1 ± 0.08 × 10 8  CFU/ml. The combined use of the studied components allowed us to achieve a significant increase in the antifungal activity of  B. subtilis  BZR 336g by 3.1 times. At the same time, the effect of synergism in their complex interaction was noted, which is probably due to a qualitative and quantitative change in the composition of  B. subtilis  BZR 336g antifungal metabolites.
