*Disease severity was calculated using the following formula:

$$\mathrm{Disease}\mathrm{severity}=\frac{\sum (\mathrm{Scale}\times \mathrm{Number}\mathrm{of}\mathrm{plants}\mathrm{infected})\times 100}{\mathrm{Total}\mathrm{number}\mathrm{of}\mathrm{plants}\times \mathrm{Maximum}\mathrm{disease}\mathrm{scale}}$$

**Blast severity reduction was estimated using the following formula:

$$\mathrm{Blast}\mathrm{severity}\mathrm{reduction}=\frac{\text{C}-\text{T}}{\text{C}}\times 100$$

C = disease severity in control.

T = disease severity in treatment.
