Brown rot, caused by Monilinia spp., is one of the most important pre- and postharvest diseases of pome and stone fruit worldwide. The disease is controlled by multiple preharvest fungicide applications, since in most European countries including Serbia, postharvest application of fungicides is not allowed. To reduce the amount of synthetic pesticides in the environment and their residues in food products, eco-friendly alternatives to synthetic pesticides became an object of many studies. Our previous investigations showed that essential oils exhibit a great potential to be used as crop protectants against many fungal plant pathogens. The aim of this study was to determine whether essential oils could be effectively used against Monilinia laxa, Monilinia fructigena and Monilinia fructicola, the most important pathogens of the genus Monilinia in stone and pome fruit in Serbia. Cultures of M. laxa, M. fructigena and M. fructicola were exposed to a volatile phase of numerous essential oil...s, including tea tree oil that is already on the market as a biofungicide. The results showed that the volatile phase of a thyme and oregano oils exhibited the highest toxicity. Further experiments in vitro, using slightly modified agar overlay technique, showed that developed formulations (emulsifiable concentrates - EC) significantly inhibited mycelial growth of Monilinia spp. Experiments in vivo, performed on inoculated apple fruits, revealed that formulation process successfully decreased evaporation of the oils from the treated areas and provided significant level of Monilinia spp. suppression, 47-61% compared to the control. To our knowledge, EC formulation of the thyme and oregano essential oils for use against Monilinia spp. has never been developed before. Presented results are initial findings and, therefore, evaluation of the activity of the developed products should be continued under field conditions to determine efficacy and to estimate economic aspects of its use.
