In vivo effect of prothioconazole + fluoxastrobin on symptoms of F. graminearum (a) and DON content (b) after point inoculation of wheat ears 14 days after infection. Wheat ears (variety Cadenza) were inoculated with two droplets of 20 μl of conidia at a concentration of 10e⁶ conidia/ml. Infection spots were indicated with a marker. Ears were subsequently treated with a tenfold dilution series of fluoxastrobin + prothioconazole starting from 0.5 g/l + 0.5 g/l. For each treatment, 10 plants were assessed for Fusarium symptoms. This experiment was repeated twice in time with analogous results. The figure represents one representative experiment. Different letters at each data point indicate differences from the control treatment after analysis with a Kruskall-Wallis and Mann-Whitney test with a sequential Bonferroni correction for multiple comparisons.
