Times indicate recordings made at seven sequential 10-day intervals. In the control group (distilled water), the absence of data in the sixth and seventh timepoints is due to the late blight outbreak and subsequent large-scale plant death and the significant difference analysis in the sixth and seventh times is based on the fifth timepoint control results. Data are presented as the average ± the standard deviation. Different lower-case letters a–d indicate a significant difference between treatments within a timepoint (P < 0.05).
