Efficacy of Copper Borax Preservative Against Wood Decay

William Abbott Bessie Woodward Michael West

In this study, a wood preservative containing active ingredients of 43.5% borax and 3.1% copper hydroxide was evaluated in soil-block tests in accordance with AWPA E10. Results suggested that the copper hydroxide was not contributing to fungal toxicity at preservative threshold levels. Thresholds determined for this preservative were very close to those previously reported for sodium borate. For this preservative, the soil-block test results in this study were less effective that field test results.
