Efficacy of copper borax preservative against wood decay

摘要

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