The plantation-grown timbers are highly susceptible to insects/pests, borers and wood rot fungus. Wood preservatives copper chrome arsenic (CCA) 2% and chloropyriphos 2% solution treated under pressure on three plantation grown timber species viz. Acacia tortilis, Prosopis juliflora and Prosopis cineraria have shown encouraging results in enhancement of shelf life by protection of wood against wood rot fungus, pests and insects. These species are grown in arid/semi arid region for sand dune stabilization/ pastureland development. Timber from these species particularly A. tortilis and P. cineraria are prone to pests and insect attack immediately after felling, for this reason wood is used only as firewood. Furniture and handicraft items made from treated and seasoned wood are exhibiting very good appearance and unaffected by deteriorating agents. Value addition of these timbers by preservative treatment and seasoning can boost the better utilization of wood for products like low cost furniture’s, curios and other handicraft items. The demand for wooden handicraft is increasing every day, application of this technique on utilization of plantation grown timbers can reduce pressure to some extent on supply of traditionally used timber species like Teak and Shisham, thus the conservation of natural resource.
