Abstract
The value of small-diameter grand fir round stock could be increased if this material could be successfully treated with preservatives and marketed as posts and poles. This paper reports the treatability of suppressed-growth grand fir posts with several common preservatives. Ammoniacal copper zinc arsenate (ACZA) and oilborne copper naphthenate were found to provide adequate treatment. Acceptable treatment was not achieved with chromated copper arsenate (CCA). The pattern of preservative penetration was erratic, especially with CCA.
