Summary Artificial inoculation of stumps with Phlebiopsis gigantea (preparation‘PgIBL’) against Heterobasidion annosum in Scots pine ( Pinus sylvestris ) stands on former agricultural lands in Poland is being performed throughout the year. The practical efficiency of the biological control appears to be influenced by the moisture content in stumps and roots. In experiment 1, dry weight loss of wood 3 months and 6 months after P. gigantea inoculation in laboratory was investigated in the stumps after salvage cutting (felling of dead and dying trees) and after thinning (routine cutting of trees) and compared with the decay of the artificially inoculated stumps under field conditions. It was found that 6 months after inoculation the dry weight loss of the samples was about 3%, 17% and 22%, respectively. In experiment 2, the decay of wood from horizontal roots collected after thinning, inoculated with P. gigantea in laboratory, was evaluated. Three months after the inoculation, the loss of dry weight wood was about 22–52%, depending on initial moisture of the roots.
