Methods: In the present experimental study, the hydroalcoholic extract of Quercus infectoria gall (Oak), was studied against saprolegnia. Minimal Inhibitory Concentration (MIC) and minimum lethal concentration were evaluated for this extract. The antimicrobial potent of Quercus infectoria gall (Oak) extract with malachite green as commercial antifungi reagent were compared. Results:Findings of this study demonstrated the antifungal properties of the extract. This antifungal effect was dose dependent where its effect was increased with increasing the extract concentration. The MIC and MLC which, was determined by the tube serial dilution method, was 300 microgram per milliliter. Conclusion: Hydro alcoholic extract of oak placenta can help to prevent fungal growth in comparison with anti-fungal activity of Malachite green. M3 ER -
