The Krasnoyarsk
territory has
a considerable supply of coniferous forest. In the process of
intensification
of forest resources and due to man’s influence the area of
natural forest is
reducing, thus, more attention should be given to forest conservation
and
preservation. Needle diseases are very dangerous for wood seedlings in
view of
anatomic and physiological features. Very often pathogenic fungi are a
reason
of needle damage and of needle blight. The study of species diversity
of needle
pathogenic fungi was realized in forest nurseries and natural forest.
Eleven
different damages were diagnosed. Pathogenic agents are members of
three
groups: Ascomycetes, Basidiomycetes
(order Uredinales)
and Deuteromycetes.
Key
words: pathogenic fungi, needle blight, damage of
rust fungi
