Values were the mean of replications. Same letter on suffix showed data were statistically same (non-significant) while different letter indicates they were significantly different at 5% level by DMRT
RG, radial growth of pathogen (mm); IZ, inhibition zone (mm), PI, per cent inhibition of mycelial growth
