Screening of Phlebiopsis gigantea (fr.) Jülich strains according to their colonization ability on pine stumps after fellings

Abstract

Biological method, consisted in stump treatment with preparations on the basis of antagonistic fungus Phlebiopsis gigantea (Fr.) J?lich has a wide application in the complex of protective measures, restricting harmfulness of Heterobasidion spp. Efficacy of pine stump wood colonization with seven strains of P. gigantea, screened during laboratory experiments, was investigated for selection of effective belarusian strains of antagonist. According to conducted experiments two strains that have the best colonization ability in forming fruiting bodies on 76.0–92.6% treated stumps in six months were selected. These strains can underline development of native biological preparation.
