Gray mold (Botrytis cinerea) is necrophytic fungal pathogen causing postharvest decay that significantly reduces the yield and quality of many horticultural crops such as tomato, grape and strawberry. Although the control of gray mold disease relies entirely on the use of chemical fungicides, there are several public concerns such as fungicide residues on fruit surface, induction of fungicides resistance in fungal pathogen and environmental pollution. Therefore, in this study, we have investigated antifungal activity of peracetic acid (PAA) on B. cinerea through various susceptibility assays. Fungi isolated from infected strawberry skin lesions were identified through the PCR amplification using several RAPD-SCAR markers specific to B. cinerea. To assess the antifungal activity of PAA against B. cinerea, disc diffusion, mycelial growth test and microdilution assay were performed. Based on the results obtained, it was shown that PAA completely inhibited fungal growth and metabolic activity at a concentration above 0.1%.
