Abstract

An alkyl ammonium compound ('Akzo' ES 255) was evaluated for its effectiveness against mould and sapstain during diffusion storage of boron-treated rubber wood. Though ES 255 at 1. 0 concentration was effective against mould (71) and sapstain (89), it was less satisfactory compared to 0. 5 sodium pentachlorophenoxide against mould (92) and sapstain (98)
