Field performance of sematan bamboo, Gigantochloa scortechinii was evaluated under the Malaysian tropical climate, along with laboratory evaluation to white-rot fungi and mold. Starch was removed from the bamboo by submerging the bamboo in the river for 6-8 weeks, kiln-dried and cut to 300 mm (L) round bamboo and 25 mm (W) x 50 mm (L) stripe for the field and laboratory test respectively. Bamboo was then treated using 10% copper chrome boron (CCB) and 10% boric acid, air-dried and exposed in the field for 1 year. Bamboo stripe was exposed to two white-rot fungi, Trametes versicolor, Pycnoporus sanguineus and one mold species, Aspergillus brasiliensis. Degradation was evaluated and compared with untreated bamboo and differentiated based on position – top, middle and bottom. Chemical compound was also analysed for relationship with the bamboo durability.
