Experimental infections were conducted in the Kladno coal mines using several strains of Trichoderma viride to control wood-decay fungi. Only one strain, isolated from a poplar branch parasitizing Chondroplea populea and Cytospora chrysosperma, was effective against Serpula lacrymans, Heterobasidion annosus, and Fomitopsis pinicola. This early biological wood protection attempt, though discontinued, offers potential for renewed research.
