Evaluation of Discoloration and Subterranean Termite Resistance of Four Furfurylated Tropical Wood Species after One-Year Outdoor Exposure

The discoloration and resistance to subterranean termite attack of four furfurylated fast-growing tropical wood species were evaluated after outdoor exposure for 1 year in Bogor, Indonesia. For comparison purposes, imidacloprid-preserved untreated samples also prepared. Discoloration all treated was measured before the furfurylation process. specimens then placed vertically three-fourths their length ground year, at which point they attack. After furfurylation, darker color than wood, while lighter. 1-year exposure, appeared have highest These had minimal weight loss, indicating a substantial protection level. Imidacloprid-preserved less attack, but more resistant wood.
