Abstract

The potential for using temperature reductions to induce biocide deposition at the end of biocide treatment was assessed using Cyproconazole to treat ponderosa pine sapwood boards. Temperature-induced deposition produced higher biocide loadings and steeper preservative gradients from the surface inward than the more commonly used pressure-induced deposition. The results are discussed in relation to treatment results, process time, and the ability to recover treatment components.
