Mold and stain fungi can be easily controlled by kiln-drying, but even this material can be rewetted during shipping and storage, allowing fungi to colonize the wood. The potential for using surface spray treatments with commercial formulations containing combinations of propiconazole, didecyldimethyl ammonium chloride, or 3-iodo-2-propynyl butylcarbamate to protect kiln-dried Douglas-fir and hem-fir lumber was evaluated over an 18-month storage period. Rewetted, untreated wood was readily colonized by fungi, while the treated boards experienced much lower levels of discoloration. Protection did appear to decline with storage time for hem-fir but not Douglas-fir. Chemical treatment of kiln-dried lumber may provide added protection against rewetting during transit and prior to installation in dry applications. [ABSTRACT FROM AUTHOR] |
