Abstract

Rubberwood [Hevea brasiliensis] treated with two preservatives, boric acid-borax (BB, a 10 boric acid equivalent solution) and BB+sodium pentachlorophenoxide (NaPCP, 0. 5), by the diffusion process, was tested for durability against Ganoderma applanatum and Lenzites palisotii (white rot fungi) using an accelerated laboratory test. Both the treatments provided high resistance to the fungi. Sapstain fungi which had grown over the treated specimens during diffusion storage were identified as Botryodiplodia theobromae, Fusarium decemcellulare [Nectria rigidiuscula], Aspergillus sydowii and Penicillium citrinum
