Abstract

Fresh fruits of several plants are susceptible to infection by several pathogenic fungi after harvest. Somesynthetic fungicides are known to be highly effective in their control on various vegetables and fruits. Inthe present study the potential fungicidal activity of the essential oils obtained by thyme (Thymus vulgaris)and vervain (Verbena officinalis), respectively, against Monilinia laxa, Monilinia fructigena, and Moniliniafructicola was tested at various concentrations in vivo. The oil of thyme was mainly composed by o-cymene (56.2%), while the main components of the oil of vervain were citral (44.5%) and isobornyl formate(45.4%). The higher concentrations of both studied EOs from vervain (1000 ppm) and thyme (500 ppm)significantly reduced the brown rot lesion diameter. The lower concentrations of vervain (500 ppm) andthyme (250 ppm) EOs resulted in low effectiveness. This research revealed the potential fungicidal rolein vivo of the essential oils on peach fruits postharvest. Moreover, the application of essential oils couldbe combined with other innovative postharvest treatments such as biocontrol agents
