Forest Research Laboratory, Miller, Donald J. (Donald James) Environmental restrictions have induced many sawmills to seek alternatives to pentachlorophenol (penta) or similar chlorinated phenols to control fungal sapstains on green lumber. Five alternative preventives were evaluated against a traditional penta product (Permatox 101) on Douglas-fir, hem-fir, and pine lumber in an accelerated 6-week test on small specimens in the laboratory and in field trials on bundled studs (2 inch x 4 inch x 8 ft) exposed outdoors for 2 and 6 months. Strong solutions of most alternative preventives provided good protection of Douglas-fir and hem-fir studs for at least 2 months during warming spring weather; some also protected pine studs. Permatox 101 provided superior protection during prolonged outdoor storage, but may permit surface growth of brown mold.

Forest Research Laboratory, Miller, Donald J. (Donald James) 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.
