Sokolova Elena G. Kulikova l Abstract Describes common fungal diseases of Russian forests, including diagnostic signs and symptoms, pathogen biology, damage caused by the disease, and methods of control. The fungal diseases are divided into two groups: those that are the most common in Russian forests and those that are found only in Russia. Within each group, diseases are subdivided by plant organ attacked, i.e. fruit, seeds, leaves, needles, roots, stems, and branches. The Authors EVGENY P.
