Potential for the use of hydroxylamine derivatives as wood preservatives

The potential of 17 hydroxylamine derivatives as wood preservatives was assessed on ponderosa pine sapwood blocks exposed to one of two decay fungi: Gloeophyllum trabeum or Trametes versicolor. Weight losses on untreated controls were generally lower with the white-rot fungus (T. versicolor) averaging 30.4 percent, while those for the brown-rot fungus (G. trabeum)were 72.0 percent. None of the test chemicals completely inhibited weight loss, although one chemical was associated with lower weight losses at the highest concentration tested. The results suggest that the hydroxlamine derivatives evaluated have little potential as wood preservatives.
