Detection of the rust fungus Chrysomyxa woronini Tranzschel in artificial planting of spruce trees in the Magadan Region territory. V.B. DOKUCHAEVA, N.E. DOKUCHAEV (Institute of Biological Problems of the North, FEB RAS, Magadan).
The rust fungus Chrysomyxa woronini in the Magadan Region was previously observed only on Siberian spruce (Picea obovata) in the Yama River basin. In 2015 it was discovered for the first time on artificial spruce plantations in the vicinities of Magadan city. Currently Ch. woronini is observed only in one of the five surveyed sites of artificial plantings. The area affected by this type of rust is approximately 5,000 sq. m. For the present this phytopathogenic fungus does not cause serious harm to the spruce plantations in Magadan region, but monitoring is needed.
