Table 4.

Disease severity (DS) is expressed as the number of point-like necrosis per plant at 7 dpi. Disease symptoms reduction (DR) was calculated as percentage ratio between plant disease severity, using water as a control. Data are represented as the mean and SD; different letters (a, b) show significantly different values after one-way ANOVA, followed by Tukey’s HSD post hoc test were performed.
