Elimination of alternative explanations for the effect of iron on treated wood
P I Morris, J K Ingram, D L Gent
Amounts of iron which had previously been found in stakes removed from ground contact reduced decay of untreated wood by four brown-rot fungi. This suggested that the effect of iron may be on the preservative. Analysis of the leachates from CCA- and ACA-treated wood blocks first exposed to rusting iron, then to a brown-rot fungus, showed that the increased decay found in the laboratory for wood exposed to iron was not due to enhanced leaching of the preservative.
