Celery EO showed inhibition zones for M. racemosus with discs impregnated with 40, 20 and 10 μL with statistically significant (p < 0.05) differences between them. Again, no antifungal activity was observed, at any concentration, against A. alternata. P. chrysogenum showed antifungal activity only at high concentration with inhibition zone of 27.7 mm.
