Abstract: The aim is to study the potential of plant essential oils for developing biological pesticides. Five kinds of essential oil from Cinnamomum aromaticum, Rosmarinus officinalis, Lavandula pedunculata, Myristica fragrans, Pelargonium graveolens were extracted by hydrodistillation. The chemical composition of essential oil was analyzed by gas chromatography-mass spectrometry (GC-MS). Alternaria solani was used as the tested material, the inhibiting effect of different plant essential oils on Alternaria solani was studied. The results showed that the main component of C.aromaticum essential oil was trans-Cinnamaldehyde (52.50%), 1,8- cineole (20.69%) was the main component in R. officinalis essential oil, linalyl acetate (33.92%) and linalool (29.29%) were the main components in L. pedunculata essential oil, GAMMA-terpinene (13.00%), (-)-4- terpineol (12.84%) and 2-carene (10.37%) were the main components in M. fragrans essential oil, and β- Citronellol (32.21% ) was the main component in P. graveolens oil. C. aromaticum essential oil had the strongest inhibitory effect on the hypha growth of Alternaria solani with EC50 of 286.62 mg/L, while the inhibitory effect of M. fragrans essential oil was the weakest. This study provided a scientific basis for screening out plant essential oil with high antifungal activity and developing C. aromaticum essential oil in the application of biological pesticides.
