This study aims to evaluate the chemical profile and fungicidal activity of the nanoemulsion of the essential oil obtained from Ba-har (Syrian pepper).The results obtained for the total phenolic content were quantified in 348.3 mg EAT g-1 and 346.21 mg EQ g-1 for flavonoids. Ba-har essential oil was most effective in inhibiting A niger, as it had the lowest MIC (200 g mL-1), followed by P. chrysogenum (250 g mL-1) and later by C. gloeosporioides...
