↵x Range of disease incidence and severity values were recorded at the end of the trial in August of each year.

↵y rAUDPC = relative area under the disease progress curve. Columns represent the AUDPC values divided by the total number of days between the first and the last assessment.

↵z Columns not connected by the same letter are statistically different according to Tukey Honest Significant Difference test (

*a*= 0.05).
