Antifungal Activity Of Rosmarinus officinalis and Pelargonium Gravelens Essential Oils Extracts Against Aspergillus Flavus,Penicillium Brachycaulon. Andalternaria alternate

The present paper aims todescribethe antifungalactivity of essential oils extracts with three concentrations which are (25,33 and 50) mg\ml at significant differences (P ≤ 0.05)of Rosemary officinalis andPelargonium gravelensessential oils extracts have been projected against some kinds of fungi (Aspergillus flavus;Penicillium brachycaulonand Alternaria alternate) .TheRosmarinus officinalis essential oils extractshave been foundto possess greater inhibitioninfluence of growth for both Alternaria alternateand Penicillium brachycaulonthat reach (100)℅ in all concentrationsrespectively, followed by Aspergillus flavus at (50) mg\ml that amountto(88.8)% ,while Pelargonium gravelensessential oils extractseffectinhibition of growth Penicillium brachycaulonat (50) mg\ml that reaches to (100)%.As well as the same concentrations higher inhibition of percentage to(79.7)% in growth of Aspergillus flavus.Alsothese extracts that inhibition percentage influence the overlapping types of concentration extract of growAlternaria alternateon SDA reached about(100)%,while the activity of extract against Penicillium brachycaulon at concenteration(50) mg\ml opposing inconted toinhibitedamounted(100)℅.As recorded inhibition ratio at the same concentered abovefor Aspergillus flavus which amounted to (82.4 )℅.The highest inhibition ratio ofAlternaria sp.growth amounts to100% when it is mixedwith Rosemaryofficinalisessential oils extracts in all concentration.The proportion ofAspergillusflavushas reached (54.1)%, in Pelargonium gravelensextract on the same fungi.
