Özet: Wood vinegar derived from Shorea laevis and oil palm empty fruit bunches (OPEFB) under two different pyrolysis temperatures of 350 and 450° C as antifungal and antitermitic  activities were assessed. The concentration of wood vinegar was 0.5, 1.0, 1.5 and 2.0% (v/v) against two fungi such as a Trametes versicolor and a Fomitopsis palustris. Meanwhile, they were tested by a no-choice test for antitermitic activities against Coptotermes formosanus with wood vinegar concentration of 2.5, 5.0, 7.5 and 10.0 % (v/v). Both wood vinegar have demonstrated strong as antifungal activity. Wood vinegar from OPEFB at pyrolysis temperature of 350 °C produced in thorough inhibition of the growth of T. versicolor at 1.5 %. The wood vinegar from S. laevis produced at 350 and 450 °C showed thorough inhibition of growth of T. versicolor at 1.5 %. Both wood vinegar required the higher concentrations to obtain the growth inhibition of F. palustris. Wood vinegar from OPEFB at 450 °C exhibited anti-termite activities to C. formosanus workers in the no-choice test. The concentration of vinegar (10 %) was needed to attain 100 % mortality against C. formosanus, meanwhile the lowest mass loss of the treated filter paper of 3.72 % was produced at pyrolysis temperature of 450 °C and concentration of wood vinegar of 10.0 %. Overall the dominant components of wood vinegar obtained from two biomass resources contained acetic acid, 2-propanone, 2-furancarboxaldehyde, butyric acid, formic acid, botanoic acid, 4-metyl phenol, 2-methoxy-4-methyl phenol and 2,6-dimethoxy phenol.
