The potential risk of fungal pathogen infection in agriculture has great adverse effects on agricultural development and human health. In this study, we explored the application of agarwood essential oil (AEO) and its main components in the development of agricultural fungicides. The compositions of AEO produced in Maoming City of Guangdong Province, China was firstly analysed by GC–MS. AEO and compounds thereof including carvacrol and longifolene were then used to perform a series of antifungal activity evaluations in vitro and in vivo against agricultural and foodborne pathogens. The in vitro results showed that the antifungal activities of AEO were comparable to those of hymexazol (a positive control), and carvacrol exhibited stronger efficacy. In vivo studies also showed that AEO and carvacrol could significantly inhibit the damage effect of Curvularia mebaldsii on the germination rate of wheat roots. Further, it was found that the germination rate exhibited a downward trend with the dose increase of AEO and carvacrol. [ABSTRACT FROM AUTHOR]
