title: Antifungal Screening of Lavender Essential oils and Essential Oil Constituents on three Post-harvest Fungal Pathogens.
abstract: A growing body of literature indicates that many synthetic pesticides have adverse effects on human, animal, and environmental health. As a result, plant-derived natural products are quickly gaining momentum as safer and less ecologically damaging alternatives due to their low toxicity, high biodegradability, and good specificity. Essential oils of Lavandula angustifolia, Lavandula x intermedia cv Grosso, and Lavandida x intermedia cv Provence as well as various mono- and sesquiterpene essential oil constituents were tested in order to assess their antifungal potential on three important agricultural pathogens: Botrytis cinerea, Mucor piriformis, and Penicillium expansum. Fungal susceptibility testing was performed using disk diffusion assays. The majority of essential oil constituents tested did not have a significant effect; however, 3-carene, carvacrol, geraniol, nerol and perillyl alcohol demonstrated significant inhibition at concentrations as low as 1 µ/mL. In vivo testing using strawberry fruit as a model system supported in vitro results and revealed that perillyl alcohol, carvacrol and 3-carene were effective in limiting infection by postharvest pathogens.
