Interactions of polysporous cultures of antagonistic fungus Peneiphora gigantea (Fr.) Massee and some decay fungi of spruce from Stara planina

Abstract

In the control of the fungus Heterobasidion annosum the most frequently applied method is stump treatment with biological preparations containing dehydrated spores of the saprophytic fungus Phlebiopsis gigantea (syn. Peniophora gigantea /Fr./ Massee). In the field, this fungus is a competitor to the fungus Heterobasidion annosum. This paper presents the results of laboratory analyses of interactions of decay fungi isolated from the root and butt of uprooted spruce trees in the Nature Park "Stara Planina", and their relation to the fungus Ph. gigantea. The interactions of these fungi were analyzed at the temperatures of 20°C, 25°C and 30°C.
