This study was designed to evaluate the antifungal activities of pure oxygenated monoterpenes (borneol, borneol acetate, camphor, carvone, 1, 8-cineole, citronellal, β-citronellol, dihydrocarvone, fenchol, fenchone, geraniol acetate, isomenthol, limonene oxide, linalool, linalool acetate, menthol, menthone, nerol, nerol acetate, terpinen-4-ol and α-terpineol) against 31 plant pathogen fungi in in vitro mycelial growth assays. Among the tested compounds, β-citronellol, nerol, menthol, terpinen-4-ol, α-terpineol, carvone, borneol and commercial benomyl had potent inhibitory effects against most of the tested fungal species. In particular, β-citronellol and nerol completely inhibited the growth of assayed fungi. Their inhibitory effects were also more stronger than commercial benomyl. Based on these results, β-citronellol, nerol as well as menthol, α-terpineol and terpinen-4-ol may be used as new antifungal compounds against plant pathogenic fungal species in agriculture.
