  • x Range of disease incidence values were recorded at the end of the trial in August 2019.

  • 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).
