Pelargonium graveolens L’Her. and Artemisia arborescens L. essential oils: Chemical composition, antifungal activity against Rhizoctonia solani and insecticidal activity against Rhysopertha dominica.

The chemical composition of thePelargonium graveolensessential oil allowed the identification of 15 compounds (93.86% of the total essential oil). The major fractions were citronellol (35%) and geraniol (28.8%). The chemical composition of theArtemisia arborescensessential oil revealed twenty-one compounds representing 93.57% of the total essential oil. The main compounds were chamazulene (31.9%) and camphor (25.8%). The insecticidal effects were tested towards the insectRhysopertha dominica.Results revealed that these two essential oils were highly effective againstR. dominicaat the dose of 50 µL on Petri dish of 8.5 cm of diameter. The antifungal activity was evaluated againstRhizoctonia solaniand results showed that both of the essential oils were highly active at a dose of 12.5 µL/20 mL of PDA. Moreover, the inhibitory effect ofP. graveolensessential oil was evidenced as stronger than that of theA. arborescensoil for all the tested doses. [ABSTRACT FROM PUBLISHER]
