Abstract
The present study deals with the fungal infections, a great amount of food losses occur worldwide. The infections caused by Penicillium digitatum, green mold agent in Citrus fruits, are just one of those losses. In this study, determining a novel environmentally-friendly antifungal product against green mold agent is aimed. Total 39 plant species, naturally growing in Kırklareli (Turkey) were scanned in terms of antifungal activity against P. digitatum. Digitalis viridiflora, Medicago lupulina and Sambucus ebulus, inhibited the micelle development of P. digitatum completely (100%), while Lythrum salicaria, Epilobium roseum and Prunella vulgaris inhibited the micelle development over 75%. D. viridiflora has showed the least MIC value (250 µg/ml) against P. digitatum. In SEM analysis, flattening, collapse and wrinkling effects of D. viridiflora on hyphae structure of P. digitatum were also observed during the present investigation. In the lemons treated with 8 mg/ml D. viridiflora aqueous extract, 73.99% regression in the lesion diameters has also been observed. As a result, in order to avoid green mold infection caused by P. digitatum occurring in lemon fruits, D. viridiflora can be used as a natural antifungal agent
