Currently, this pathogen exhibits increasing resistanceto conventional fungicides; therefore, better control methods and novel compounds with a morespecific mechanism of action but without biocidal e ects, are required. In this work, several naturalcompounds to control B. cinerea were analyzed in vitro. Detected e ects were dependent on thestage of fungus development, and 3-phenyl-1-propanol displayed the most potent inhibition ofin vitro germination, germ tube development, and sporulation. However, it had lower protectionof leaves and postharvest fruit in plant infection. Isoeugenol and 1-phenylethanol exhibited lowerinhibition of in vitro germination and sporulation, but at the highest concentrations, they inhibitedgerm tube elongation. Although the lowest rates of foliage infection were recorded using isoeugenoland 3-phenyl-1-propanol, 1-phenylethanol significantly decreased the disease in postharvest tomatofruit, with an e cacy like Mancozeb, but at 18 times lower micromolar concentration. All compoundsresulted in high cell viability after spores were removed from the treatment solution exhibited highcell viability, suggesting a non-biocidal e ect. The diversity of in vitro and in-plant e ects seems toindicate a di erent mechanism of action.
