Antifungal Activity of Thirty Essential Oils to Control Pathogenic Fungi of Postharvest Decay
Essential oils (EOs) extracted from aromatic or medicinal plants are biodegradable, safe, and regarded as alternatives to chemical pesticides to reduce fungal species attacking different crops. In this study, thirty EOs at 0.5 mg/mL were evaluated for in vitro growth inhibition of the main postharve...

| description | Essential oils (EOs) extracted from aromatic or medicinal plants are biodegradable, safe, and regarded as alternatives to chemical pesticides to reduce fungal species attacking different crops. In this study, thirty EOs at 0.5 mg/mL were evaluated for in vitro growth inhibition of the main postharvest fungi, which are <i>Alternaria alternata</i>, <i>Botrytis cinerea</i>, and <i>Penicillium italicum</i>. <i>Cinnamomum verrum</i> EO completely inhibited the mycelial growth of <i>A. alternata</i> and <i>B. cinerea</i>, and <i>Syzygium aromaticum</i> EO completely inhibited the mycelia of <i>A. alternata</i>. <i>B. cinerea</i> mycelial growth was completely inhibited by <i>Gautheria fragrantissima</i>, <i>Cymbopogon nardus</i>, <i>Pelargonium asperum</i>, and <i>Cupressus sempervirens</i> EOs. <i>G. fragrantissima</i> EO inhibited the mycelia growth of <i>P. italicum</i> by 98%. Overall, <i>B. cinerea</i> displayed the highest sensitivity to EOs than <i>P. italicum</i> and <i>A. alternata</i>. <i>G. fragrantissima</i>, <i>C. sempervirens</i>, <i>C. nardus</i>, <i>P. asperum</i>, <i>Mentha piperita</i>, <i>Foeniculum vulgare</i>, <i>C. verrum</i>, and <i>S. aromaticum</i> EOs showed the highest inhibition for these three pathogens. Minimum inhibitory concentrations were lower for <i>C. verrum</i> and <i>S. aromaticum</i> EOs, ranging between 0.31 and 0.45 mg/mL and 0.37 to 0.57 mg/mL, respectively, against the three pathogens. The tested EOs inhibited the in vitro growth of three of the main postharvest fungal pathogens. Further studies are needed to confirm these activities in vivo. |
