In order to determine the antifungal effect of essential oils, the filter paper adhered to the covers of the petri dishes was impregnated with the micropipette. Additionally, it was suggested that the plant essential oils inhibited the mycelial growth of FOM and FOC compared to the control. As a result of the study, 8 µlpetri <sup>-1 </sup> dose of <i>T. spicata </i>essential oil inhibited the mycelium growth of FOC and FOM by 100%.

In the study, LC <sub>50 </sub> and LC <sub>90 </sub> values were also calculated by carrying out a dose-effect study. The LC <sub>50 </sub> and LC <sub>90 </sub> values of FOM and FOC for <i> T. spicata </i>’nın <i> </i>essential oil were calculated as 0.58-1.26 µL and 0.46-1.07 µL, respectively, while the LC <sub>50 </sub> and LC <sub>90 </sub> values, of FOM and FOC for <i> <span style="background-image: initial; background-position: initial; background-size: initial; background-repeat: initial; background-attachment: initial; background-origin: initial; background-clip: initial;">R. officinalis </span> </i> essential oil were calculated as 4.04-37.56 µL and 3.92-95.84 µL respectively.
