Abstract :The bioactivities and antioxidant properties of essential oils and plant extractives prove a safe usage in food applications, pharmaceutical research and many other utilization areas for years. The objective of this study is to evaluate the decay resistance of wood treated with various natural plant oil or water extracts. Scots pine wood specimens (Pinus sylvestris L.) treated with fourteen plant oils and water extract of nineteen plant species were subjected to brown rot fungus, Coniophora puteana for two months. Cinnamon, mint, garlic, thyme and onion oils showed better protection than other tested oils. Water extracts of fennel were able to protect wood specimens against decay fungus, and treated wood showed the weight loss less than 5% based on the initial oven dry weight. Nearly all treated specimens gave better efficiency against fungal decay compared to controls; however, the preservation effect was not within the range of efficiency needed for a successful wood preservative according to EN standards.
