The performance of boron and a boron/fluoride combination was assessed in Douglas fir (Pseudotsuga menziesii) poles over 1 to 3 year periods. Both chemical formulations diffused well through the wetter, groundline zone of the poles, although the initial release rate of the boron in the fused borate rods was somewhat slower than that found with the combination. Chemical levels in the groundline zone remained above those required for control of active fungal attack.
