Antifungal activity of lemongrass and thyme essential oils and effect on gray mold control and postharvest quality of ‘Italia’ grape

The aim of this study was to test the hypothesis that lemongrass and thyme essential oils (EOs) reduce Botrytis cinerea development control gray mold in ‘Italia’ grapes. fungitoxicity evaluation performed by EOs direct contact with pathogen, culture medium, exposure volatile phase. Individualized rachis berries were inoculated subcuticular injection a conidia suspension after 4 hours sprayed (100 1,000 mg·L-1), or blend (500 mg·L-1 + 100 lemongrass), then stored at 25 °C / 75% relative humidity. To verify possibility protect fruit against B. cinerea, 400 each (200 200 24 cinerea. On clusters, (800 mg·L-1) lemongrass) inoculation 1 °C. disease incidence severity analyzed, as well quality attributes. had antimicrobial effect, in-vitro, incorporated into medium volatilization detached berries, oil reduced when before spraying. In 800 significantly only fruits kept °C, without impairing clusters quality, which could be an alternative for management postharvest.
