Table 2.
Summary of Septoria tritici blotch (STB) assessments. STB incidence and conditional severity were assessed at the level of individual leaf layers, namely, the flag leaf (Fl0), the penultimate leaf (Fl1), and the ante-penultimate leaf (Fl2). Conditional severity was measured as percent leaf area covered by lesions (PLACL). Severity was calculated as the product of STB incidence and conditional severity. Values are reported separately for non-inoculated control plots and inoculated plots, separated by a slash. Mean values across all plots are reported, with minima and maxima in brackets. Disease assessments were carried out on five dates (t1–t5) covering the growth phases of 15 days after inoculation (dai) to 41 dai.
