The paper deals with the present state of necrotic disease of beech in the growth stages of self-seeding, advance growth, thicket, small pole stage, pole stage and maturing stand from four localities of Central and Eastern Slovakia. We found out that the self-seeding was affected by the necrotic disease to the least extent. The strongest negative changes in the necrotic disease measured in terms of its frequency were recorded in the stage of advance growth. In later stages the trend of negative changes in necrotic disease became more moderate and was accompanied by small fluctuations. The lowest degree of necrotic disease expressed by means of stem necrotisation index (INK) was in the small pole stage, it moderately increased in the pole stage and in maturing stands. The frequency of stem necrotisation in maturing stands ranged from 89% to 96%. The results confirm the fact that the necrotic disease belongs to significant phytopathological problems influencing development of beech stands.Keywords:
