Abstract

Biological control of Heterobasidion annosum in the forest by non-pathogenic wood-destroying fungi.

Abstract

Investigations are reported on the possibility of using non-pathogenic wood destroying fungi to prevent aerial basidiospore infections in fresh conifer stumps and/or to degrade stumps. The experiments were carried out with fresh Picea abies stumps inoculated with H. annosum in Italy. Seven stump pretreatments with fungi with a good capacity for degrading conifer wood in vitro were compared with Trichoderma viride, and various chemical treatments. Good protection against infection was provided only by disodium octoborate tetrahydrate, T. viride,Phlebiopsis gigantea and urea. The most rapid stump degradation was by P. gigantea, Hypholoma fasciculare and Fomitopsis pinicola.
