Preliminary evaluation of efficacy of copper in combination with boron and NHA (N'-N-(1, 8-naphthalyl) hydroxylamine) against wood decay
2008 - IRG/WP 08-30452
In this study, efficacy of various combinations of copper sulfate with either boric acid or calcium precipitating agent, NHA-Na (N'-N-(1, 8-naphthalyl) hydroxylamine) was evaluated. Wood specimens were treated with either 1%, 0.5%, or 0.1% concentrations of copper sulfate, boric acid, NHA-Na, copper sulfate + boric acid, or copper sulfate + NHA-Na mixtures. Treated specimens were subjecte...

Comparison of untreated plywood and untreated LVL in a field trial against Coptotermes acinaciformis and in laboratory trials against Tyromyces palustris and Coniophora puteana
2014 - IRG/WP 14-40671
In Australasia, efficacy data obtained on plywood is generally acceptable for laminated veneer lumber (LVL) and vice versa. This is particularly the case with glueline treatment approvals. The rationale is that the two wood products have predominately the same basic structure with the key difference being orientation of the veneer. LVL typically has all veneers in parallel while plywood typical...
