Antifungal activity of the essential oil from Magnolia cylindrica on nine phytopathogenic fungi

    Corresponding author: ZHANG Li-qin1

Abstract: To exploit plant essential oils as botanical fungicides. The essential oil from Magnolia cylindrica was evaluated for its antifungal activity in vitro by using mycelial growth rate method on nine fungi: Rhizoctonia solani,Alternaria solani,Valsa mali,Fusarium graminerum,Bipolaris maydis,Exserohilum turcicum,Fusarium oxysporum f. vasinfectum,Sclerotinia sclerotiorum and Botrytis cinerea. In addition,protective and curative effect of the M. cylindrica oil against B. cinerea on tomato was tested in vivo. In vitro the results showed that the essential oil of M. cylindrica at 500 μL ·L-1 was highly antifungal on the most of the tested fungi. Inhibition rates to the oil from the most sensitive fungi were 95.23%(V. mali) and 93.83% (F. graminerum).The half maximal effective concentration(EC50) of six sensitive fungi ranged from 147.94(V. mali) to 223.73 μL·L-1(S. sclerotiorum). In vivo with tomato,the concentration of the M. cylindrica oil at 1 000 μL·L-1 had higher efficiency on B. cinerea than did of 500 μL·L-1 oil and 100 mg·L-1 triadimefon. This study indicated that the essential oil of M. cylindrica had a high antifungal efficacy,however,further study was needed to provide experimental data for development of botanical fungicides from essential oils of M. cylindrica and other woody plants.
