^aGrowth rate and conidiation were measured after incubating for 3 and 5 days, respectively. Mean and standard deviation were calculated from three replicates. The same letter indicated there was no significant difference. Different letters were used to mark statistically significant differences (P = 0.05).

^bDON/Ergosterol ratio was determined with 2-week-old rice grain cultures. Ergosterol was measured to quantify fungal biomass.

^cN/A, not assayed.
