Abstract

In the Republic of Belarus reforestation is carried out on considerable surface areas. Therefore, much attention is paid to the health of the planting material in forest nurseries. Modern DNA analysis methods have shown for the first time the prevalence and harmfulness of Phoma blight of Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies L.) in most forest nurseries of Belarus. The main symptoms of Phoma blight depend on the type and age of plants and the elements of the cultivation technology. The species composition of causative agents of disease in planting material has been updated by DNA analysis methods and the pathogenicity of Phoma spp. was proven on plant tissues.
