The inhibitory effect of eight natural oils on ten pathogenic fungi isolated from the digestive and respiratory tracts of dead chickens in Kena Governorate showed that crude peppermint oil only has a highest effect against some isolated fungi and a low response against others. While its 10% and 2% oil concentrations failed to give any effect against all the tested fungi. Crude chamomile and pelargonium oils showed moderate effect against all isolated fungi. The effect of different dilutions of chamomile, cumin and celery oils appeared that the 10% concentration showed more effective than the crude oil. Lemongrass and basil oils have almost the same behaviour towards the isolated fungi as the crude oils and the 10% concentration affected them greatly. On the other hand 2% basil oil gave no effect at all. Critical concentrations of the efficient oils against isolated fungi were calculated. The most efficient oils were lemongrass against Aspergillus flavipes, chamomile against A. fumigatus and cumin against A. nidulans, while cumin against A. glaucus, clove against A. flavus were chamomile against A. flavus and clove against A. flavipes were the lowest efficient oils.
