A novel anti-sapstain formulation, BAM, consisting of 2-(thiocyanomethylthio) benzothiazole (TCMTB) and methylene bis thiocyanate (MBT) was evaluated for ist anti-sapstain performance in the laboratory and in the field as well. BAM proved effective in controlling the growth of molds and a sapstaining fungus in the standardized Japan Wood Preserving Association (JWPA) tests. All the test fungi could not show any growth on the boards treated at 1% (100 times dilution), and at 0.67% of BAM only Gliocladium virens grew very slightly. In the field tests, BAM maintained good protection for 1.5 months when freshly sawn pine boards were dipped in 1% aqueous solution for 3-10 minutes. The present results definitely support that BAM has a high potential to replace the currently used anti-sapstain formulations containing chlorinated phenols.
