Comparison of Wood Preservatives in Mississippi Post Study: 1975 Progress Report.
Abstract
To evaluate the effectiveness of various wood preservatives, service records of treated southern yellow pine fenceposts installed on the Harrison Experimental Forest, Saucier, Miss., have been compared periodically since 1936. In contrast to the 3.3 years average life of the untreated control posts, nine preservatives, after approximately 37 years, have had less than 60 percent of their posts fail and indicate an average life of well over 30 years. Two groups of treated posts installed in 1949 have failed completely: No. 2 distillate with an average life of 6.2 years and Wyoming residual with an average life of 9.0 years. Preservatives performing better in this installation include 15 groups with no failures after 25 years and 16 groups with over 10 percent failures, permitting estimated average life values of 23 to 38 years.
