EFFECTIVENESS OF AQUEOUS EXTRACTS OF Zizyphus vulgaris AND Nerium oleander LEAVES AGAINST Aspergillus ochraceus

Abstract

A laboratory experiment was conducted at Plant Pathology Lab. in Directorate of Diyala Agriculture during November 2017, to study the effect of the Aqueous extracts of Zizyphus vulgaris and Nerium oleander leaves at four concentrations to each extraction 10, 20, 30 and 40 % against Aspergillus ochraceus. The results showed that all the concentration of the Aqueous extracts of Zizyphus vulgaris and Nerium oleander leaves led to inhibition of the fungi compared to the control treatment. Zizyphus vulgaris extract conc.40% was the most efficiency in inhibition of fungus growth which reached 75.68 % with the growth rate 0.9 cm compared to control 3.7 cm, While Nerium oleander extract conc.40% was efficiency in inhibition of fungus growth which reached 40.54 % with the growth rate 2.2 cm.
