Description

This paper compares two new formulations of creosote and one pigment-emulsified creosote (PEC) with a formulation of creosote that met requirements of the AWPA standard P1/P13. Two softwood and two hardwood species were treated to four retention levels with each formulation. The evaluation of the four creosote formulations was done using (1) soil-block tests, (2) fungal cellar tests, and (3) field tests. This paper briefly discusses results from the soil-block tests, and updates previous reports to three years of fungal cellar tests and five years of field exposure in Saucier, Mississippi. Data from the latter two evaluation methods show that softwoods are generally protected better than hardwoods. Data indicate the retention is directly related to performance in both softwood and hardwood species.
