In this study, we investigated anti-fungal properties of Marrubium vulgare L. plant extracts dissolved in four different solvents against five different plant pathogenic fungi Fusarium oxysporum f. sp. lycopersici, Macrophamina phaseolina, Phytopthora infestans, Sclerotinia sclerotiorum and Rhizoctania solani. We used 1.0%, 2.5% and 5.0% plant extract concentrations against these fungi species which cause significant decrease in production yield of certain plants. In all pathogenic fungi species analyzed, we observed an increase in the anti-fungal effect of Marrubium vulgare L. plant extract preparations in a dose-dependent manner. Marrubium vulgare L. extracts dissolved in chloroform and dichloromethane at 2.5% concentration showed higher inhibition against Fusarium oxysporum compared to other solvents at this concentration. At the same concentration, extracts dissolved in methanol resulted in higher anti-fungal activity against Phytopthora infestans and intermediate activity against Macrophamina phaseolina and Sclerotinia sclerotiorum. As a result, it can be stated that Marrubium vulgare L. plant extracts dissolved in different solvents display anti-fungal properties against certain plant pathogens.
