n.d.: not detected (growth not different from control); One way-ANOVA was applied to estimate the effect of different essential oil compound (EOC) combinations on fungal biomass reduction; the least significant difference (LSD) values (p ≤ 0.05) were calculated to separate mean values for each strain: P. digitatum, 3.3%; B. cinerea, 2.8%; M. laxa, 0.9%; P. italicum and A. alternata, 0%. Mean values with different lowercase letters differ significantly (p ≤ 0.05).
