Abstract

Five dominant species of fungi were identified by morphological and molecular methods (Aspergillus niger, Penicillium fimorum , Penicllium digtaum, Sclerotinia sclerotiorum , Alternaria alternate. our study showed the antifungal effects of lemongrass(Cymbopogon citratus L) and rosemary(Rosmarinus officinalis L), essential oils (E.O) against the identified fungi which were determined in vitro conditions. Different concentrations were tested ( 500, 1000.1500) ppm. 1500ppm of lemongrass E.O showed 100% inhibitory effect against the tested fungi, whereas Rosemary (E.O) were less effective at the same concentration. The essential oils of lemongrass showed significant inhibitory effects against Aspergillus niger , Alternaria alternate when compared with rosemary oil. While the effect of rosemary oil had a clear effect on both Penicillium fimorum and Penicllium digtaum. In general, all tested essential oils showed. Inhibitory effect against all selected fungi
