Douglas‐fir [ Pseudotsuga menziesii (Mirb.) Franco] stumps infested with Phellinus weirii (Murr.) Gilb. were inoculated with the antagonist Trichoderma viride Pers.: Fr. Colonization of the stumps by Trichoderma spp. after one year was significantly higher in the upper 10‐cm than in the middle or lower 10‐cm section even though inoculum was present at all levels. A pellet inoculum made from fermented barley grains and spores proved to be superior inoculum to colonized dowels, but no difference was found among the three isolates of T. viride tested. Decayed wood was more readily colonized than stained wood and was much more readily colonized than sound wood.
