- Production of hardwood lumber (mostly red alder) has been a small but growing part of the forest products industry in the Pacific Northwest. In laboratory tests, Rodewod® 200 EC plus borax protected alder at nearly all levels tested. Eight other chemicals provided some protection at the highest level tested. Fungal-stain preventive treatments were evaluated on red alder lumber in both an accelerated 6-week test on small specimens In the laboratory and on bundled boards (1 inch x 4 inches x 8 feet) exposed outdoors for 2 or 6 months. Strong solutions of RODEWOD® 300. PQ-8 plus borax, and Permatox 101 protected freshly sawed red alder lumber that was solid-piled and stored for 2 months during which summer temperatures peaked. None of the treatments provided good protection through 6 months of storage that included summer weather.
