    Abstract: Laboratory evaluation of Cashewnut Shell Liquid (CNSL) as a wood preservative by the weight loss method was studied. Test blocks of <I>Triplochiton scleroxylon </I>were treated at concentration levels of 4, 8, 12, 16, 20, 24, 28 and 32% using pressure impregnation method which resulted into substantial penetration and absorption of CNSL by the test blocks of <I>Triplochiton scleroxylon</I>. The treated test blocks were thereafter placed inside Kolle-flasks containing active growths of <I>Coriolopsis polyzona</I>,<I> Pycnoporus sangineus</I>,<I> Ganoderma lucidum </I>and <I>Lenzites palisoti</I> for 16 weeks. From the results obtained, the concentration levels at which the preservative was applied were highly significant at p<0.01. The CNSL was found to prevent weight loss at concentration above 8%. The recommended killing point concentration (KPC) against the micro-organisms as obtained in this study is 16%.
