Abstract
As a result of phytopathological investigation of birch (Betula pendula) stands in Krasnoyarsk group of areas (south of Middle Siberia) the newly appeared and existing nidi of bacterial dropsy were discovered. The influence of growth conditions on infection rate in birch forests and the relation of disease prevalence with characteristics of forest inventory were observed. The patterns of tree affection within the limits of phytocenoses and the influence of disease on sanitary state of birch forests were discussed.
