Abstract
Wood is most preferred structural material throughout the world and is considered as a complex biological composite with ubiquitous nature. Throughout the world there is an immense pressure on primary durable timbers due to their ever increasing demand. To reduce pressure on the primary species like; Teak, Sal and Deodar etc. one has to look for the other lesser known or secondary species as an alternative. Durability of these species can be enhanced with application of different preservatives and for this one of the best approach is to use herbal based ecofriendly preservatives rather than hazardous chemicals. In this study, the antifungal activity of Acorus calamus rhizome extract was tested on less durable local wood species. The results showed that average growth of Polyporus fungus on taken wood samples were retarded up to 69.44% after applying 2% concentration of rhizome extract and act as suitable bio-preservative for non durable wood species.
