LABORATORY EVALUATION OF PRESERVATIVE TREATED RUBBERWOOD AGAINST FUNGI*

Abstract

Rubberwood treated with two preservatives, namely Boric acid-Borax (BB) and BB+Sodium pentachlorophenoxide (NaPCP), by diffusion process, was tested for durability against Ganoderma applanatum and Lenzites palisotii, two white rot fungi using accelerated laboratory test. Both the treatments provided high resistance against the fungi. The sapstain fungi grown over the treated specimens during diffusion storage were identified as Botryodiplodia theobromae, Fusarium decemcellulare, Aspergillus sydowii and Penicillium citrinum.
