Studies at the Savannah River Plant near Aiken, S.C. show that cutting slash pine and inoculating the stumps with Fomes annosus caused mortality of adjacent trees regardless of the month of inoculation. Greatest mortality occurred from March, April, May, and June inoculations and least from January and July inoculations. Fomes annosus was isolated from 52 of the trees adjacent to be inoculated stumps and from 10 adjacent to the controls. Slash pines were also cut monthly and half the stumps treated with borax. Only five trees adjacent to the borax treated stumps died while 58 died adjacent to the non-treated stumps. Some trees died each month. The root system of 33 twenty-five-year-old slash pines were excavated and all suspected F. annosus infection points sampled. Although most of the trees appeared healthy, some infection points were found on every tree. Sixty-five percent of all the main laterals had infection points. X-ray analysis of increment cores of wood from 15-year-old longleaf, loblolly, shortleaf, slash and Virginia pines after one year in axenic culture of F. annosus showed that the root wood of slash pine decayed more rapidly than the other species.
