Abstract: Conventional wood preservatives are not only toxic to target bio-deterioration organisms but also to man, other organisms and the environment. In an effort to find preservatives that are less or non- toxic to man, other organisms and the environment, efficacy of heartwood water extractives (0.65g/ml) of Tectona grandis (teak) and Distemonanthus benthamianus (bonsamdua) was tested on five selected less used timer species (LUS): Sterculiaoblonga (ohaa), Antiaristoxicaria (kyenkyen), Canariumschweinfurthii (bediwonua), Celtiszenkeri (esa-kokoo) and Colagigantea (watapuo) by brushing and immersion and exposed to the ground for 8 months following a modified EN 252. Regardless of extract retention in selected LUS, Bonsamdua extract improved their durability more than that of Teak. Improved durability of selected LUS was ranked as follows: Sterculiaoblonga>Colagigantea>Celtiszenkeri>Antiaristoxicaria>Canariumschweinfurthii. Though extracts showed reduced efficacy with time, indications were that they could be employed to control wood pests.
