Douglas‐fir [Pseudotsuga menziesii (Mirb.) Franco] stumps infested with Phellinus weirii (Murr.) Gilb. were inoculated with pellets formulated from fermented barley and spores of three isolates of Trichoderma viride Pers.: Fr. After one year, Trichoderma spp. were isolated from stumps inoculated in June less frequently (12 %) than those inoculated in February (23 %) or in October (29 %). Isolations of Trichoderma spp. from stumps with advanced decay were more frequent (46 %) than from stained stumps (12 %) or from sound stumps (2 %). Isolation success was directly related to wood decay at point of sampling, nearness to source of inoculum, and nearness to stump surface.
