The chemical composition of essential oils isolated from the leaves and flowers of Origanum glandulosum by hydrodistillation was analyzed by Gas chromatography (GC) showed the presence of 48 compounds, representing 96.73% of total oil, were identified. Oregano oil was found to be rich in carvacrol (48.42%), γ–Terpinéne (27.09%), Para-Cymène (16.9%) and β-Caryophyllène (3.45%) and characterized by relatively high amounts of phenol, monoterpenes hydrocarbons and sesquiterpenes. Results of the antifungal testing by in vitro volatilty assay showed that the oil significantly inhibit the growth of two spécies of genus : Botryosphaeria. The results of this study showed that the toxicity of the oregano oil vary with increasing concentration of applied doses on the one hand, and a relatively gradual efficiency versus time, which results in improved efficiency on the other.
