Abstract The ability of cinnamon, clove, lemon grass, oregano and palmarosa essential oils to prevent growth of and fumonisin B 1 (FB 1 ) production by Fusarium verticillioides at different water activity (0.95 and 0.995 a w ) and temperature (20 and 30 °C) levels in irradiated maize grain was evaluated. All the essential oils inhibited growth of F verticillioides isolates under all conditions tested, but FB 1 production was only inhibited at 30 °C and 0.995 a w . Moreover, stimulation of toxin production was found under certain environmental conditions. None of the essential oils showed a significantly greater ability to inhibit FB 1 production when compared with the others. At 1000 mg essential oil kg −1 maize the essential oils showed a greater inhibitory effect on growth of F verticillioides than at 500 mg kg −1 , but there was no difference in FB 1 production between the two levels of essential oil.
