STUDY OF GROUNDLINE TREATMENTS APPLIED TO FIVE POLE SPECIES
Abstract
Field tests were made on pressure-treated pole stubs of 5 important pole species at 3 locations, under different climatic conditions, to determine the distribution of preservative after application of 7 supplementary groundline treatments. Maximum concentrations of the groundline preservatives, pentachlorophenol and NaFl, were found within 1 yr after application under dry site conditions, and within 3 mo under somewhat wetter conditions. Two years after groundline treatments by surface applications, the preservatives, pentachlorophenol and/or NaFl, were confined mostly to the outer 1/2-inch zone of the pole. The concentration of NaFl in the outer zone was usually less than that required to inhibit the growth of decay fungi, while that of pentachlorophenol was greater than that necessary for decay control.
