Values are mean ± SD.
–, no inhibition zone; +, weak inhibition with inhibition zone <5 mm, growth of the fungus was stopped at the bacterial-streak line; ++, moderate inhibition with inhibition zone 5–10 mm; +++, strong inhibition with inhibition >10 mm. Different letters indicate significantly different at 5% level by Duncan’s new multiple range test. 1Inhibition rate = (control colony radius − treatment colony radius)/control colony radius × 100%. 2Inhibition rate = Inhibition zone width/control colony radius × 100%.
