Development of disease severity over three timepoints (TP1–TP3) on P. leucotricha infected apple saplings. One inoculated group (IT) was treated with a synthetic fungicide at TP2, the other remained untreated (IU). Both treatments were compared to an uninoculated control group (NC). Disease severity was rated on a 0–5 scale and the mean values and standard deviation of 9–35 replicates are shown. Significant differences in disease severity between the three groups at TP2 and TP3 were assessed by Dunn’s test with Benjamini–Hochberg correction for multiple testing
