Spread of the disease in the scots pine plantation as a result of the artificial inoculation of stumps with mycelium of Heterobasidion annosum

The presence of the fruit bodies and mycelium in roots, number of dead trees and the root-rot gaps extend were the measure of disease development. The results confirmed the efficacy of the inoculation method and possibility to assess the development of the pathogen in the stand.
