Fungal colonization of slash pine stumps, exposed at 15-day intervals throughout one year in southern Georgia, indicated that the hazard of stump infection was not accurately indicated by disc-trap evaluation of airborne spores of Fomes annosus. Freshly exposed stumps became infected by F. annosus only from mid-October to mid-December, and other stumps inoculated with F. annosus became infected only between mid-September and February. F. annosus was not detected in stumps which were treated with borax or oidia of Peniophora gigantea, then inoculated with conidia of F. annosus. The three principal factors influencing the establishment rate of F. annosus were (a) the selective toxicity of borax on F. annosus, (b) the high temperatures during the summer which curtail sporulation and can kill spores on the stump surface, and (c) the high populations of other competing fungi during late winter and spring which enable them to successfully colonize the stumps, thus excluding F. annosus.
