Wilt incidence was calculated as the percentage of dead plants
(disease score 5) at the evaluation date to the total number of
plants in the treatment. Additionally, disease severity was calculated
as the mean of disease scores at the evaluation date. The area
under the disease progress curve (AUDPC) for each plant in each
treatment and experiment was calculated on the basis of disease
severity and wilt incidence using the trapezoid integration of the
disease progress curve over time using the following equation
