Effectiveness of the Influence of Selected Essential Oils on the Growth of Parasitic <i>Fusarium</i> Isolated from Wheat Kernels from Central Europe
The aim of the study was to determine the effectiveness of selected seven commercial essential oils (EsO) (grapefruit, lemongrass, tea tree (TTO), thyme, verbena, cajeput, and <i>Litsea cubeba</i>) on isolates of common Central European parasitic fungal species of <i>Fusarium</i...

The study was conducted in 2 stages. At each stage, the fungicidal activity of EsO (with concentrations of 0.025; 0.05; 0.125; 0.25; 0.50; 1.0, and 2.0%) against <i>Fusarium</i> spp. was evaluated using the disc plate method and zones of growth inhibition were measured. At the first stage, the fungistatic activity of EsO was evaluated against four species of <i>Fusarium</i> from the Polish population (<i>F. avenaceum</i> FAPL, <i>F. culmorum</i> FCPL, <i>F. graminearum</i> FGPL and <i>F. oxysporum</i> FOPL). The correlation coefficient between the mycelial growth rate index (T) and the fungistatic activity (FA) was calculated. At the second stage, on the basis of the mycelium growth rate index, the effectiveness of the EsO in limiting the development of <i>Fusarium</i> isolates from the German population (<i>F. culmorum</i> FC1D, <i>F. culmorum</i> FC2D, <i>F. graminearum</i> FG1D, <i>F. graminearum</i> FG2D and <i>F. poae</i> FP0D) was assessed. The first and second stage results presented as a growth rate index were then used to indicate essential oils (as potential natural fungicides) effectively limiting the development of various common Central European parasitic species <i>Fusarium</i> spp. Finally, the sensitivity of four <i>Fusarium</i> isolates from the Polish population and five <i>Fusarium</i> isolates from the German population was compared.
