@article{Taş_Karaca_2015, title={Effects of Some Essential Oils on Mycelial Growth of Penicillium expansum Link and Blue Mold Severity on Apple}, volume={3}, url={https://www.ajouronline.com/index.php/AJAFS/article/view/3424}, abstractNote={In this study, in vitro and in vivo antifungal effects of the essential oils of oregano (Origanum minutiflorum), European pennyroyal (Mentha pulegium) and germander (Teucrium polium) plants, naturally growing in the Mediterranean Region, against Penicillium expansum, storage rot agent of apples, were investigated. In vitro fumigant activities of 1, 2.5, 5 ve 10 µl/petri doses of the essential oils were determined against three virulent isolates of the pathogen and compared with the efficiency of fungicide Thiabendazole which is registered and commonly used against the pathogen. As a result, it was found that antifungal effects of the essential oils increased with the increasing doses and oregano oil at doses over 2,5 µl/petri showed similar effect with the fungicide and totally inhibited the mycelial growth of the P. expansum isolates. This effect was found to be fungistatic at 2,5 µl/petri dose, while it was fungicidal at higher doses. Antifungal effects of the essential oils of other plants were lower. In vivo experiment showed that none of the essential oils were as effective as the fungicide against the pathogen and inhibition rates at 10 µl dose changed between 55-88%. In consequence, promising results on the possible use of oregano oil in the postharvest control of P. expansum were obtained.}, number={6}, journal={Asian Journal of Agriculture and Food Sciences}, author={Taş, Leyla and Karaca, Gürsel}, year={2015}, month={Dec.} }
