Abstract
Spread and development of ash dieback caused by invasive pathogen Hymenoscyphus pseudoalbidus were assessed in the stands of the forest-steppe part of Sumy region, forest-steppe and steppe part of Kharkov region. The part of ash trees with symptoms of dieback was the highest in the stands of the steppe part of Kharkov region and the lowest in the stands of the forest-steppe part of Sumy region. Among ash provenances tests of Sumy region, the highest spread and development of ash dieback (50 и 1,4 %) were evaluated for Steppe provenances. In all investigated stands and provenances the trend is revealed to increase the spread and development of ash dieback with increase of Kraft class.
