Subterranean termites are a major factor in the biodegradation of wood constructor products. In this study the efficacy of wood treated with micronized copper, zinc oxide and their mixture was compared to that of wood treated with soluble amine copper oxide with subterranean termites in a laboratory test. All of the formulations tested were effective in controlling wood degradation by the termites, with the copper being slight more effective than zinc and micronized copper being slightly more effective that amine copper.
