抄録

One hundred and thirteen strains of Trichoderma spp., mycoparacite-fungi, isolated mainly from some green houses for cultivation of Lentinula edodes in Hokkaido were evaluated in terms of the superior growth on PDA (potato-dextrose-agar) plate-madia of pH≒9 and the antagonistic effects against wood rot fungi (Fomitopsis palustris MAFF 420001 and Trametes versicolor NBRC 30340).

Three strains of Trichoderma spp. (ANCT-05013，ANCT-05083，ANCT -05103) which were inoculated individually to charcoal particles strongly inhibited the wood rot fungi.

ANCT-05013 and ANCT-05103 which had been superior in ability to protect wood from rot, were accepted as NBRC 113097 and NBRC 113098, respectively (January, 2018).
