An evaluation of chemical treatments for the protection of radiata pine logs from fungal degrade

Busan 30, Busan 1009, Mitrol PQ375. and sodium pentachlorophenoxide (NaPCP) plus have been evaluated as antisapstain treatments for the long-term protection of debarked radiata pine logs. After 3 months' winter-spring storage, treated debarked logs had less surface and internal sapstain than 'control' logs. After 6 months' storage all logs had internal sapstain and decay. Busan 30 was the most effective treatment in preventing internal degrade although 1.5% a.i. NaPCP plus 1.5% borax was more effective in preventing decay.
