Glueline fungicides in veneer based engineered wood products – updated results from laboratory work for the H1.2 hazard class in New Zealand

Results from New Zealand H1.2 ‘bin’ trials containing plywood glueline treated with triadimefon and cyproconazole were reported in 2012 (IRG/WP 12-30593). One of these trials has continued to the present day (2108) and updated results of this trial are reported. The triadimefon and cyproconazole glueline treatment continues to compare with, or outperform, the reference preservative used, being propiconazole and tebuconazole applied as a light organic solvent preservative treatment.
