First report of Mycosphaerella pini in Estonia
In autumn 2006, the presence of Mycosphaerella pini (anamorph Dothistroma septosporum – EU Annexes) was observed for the first time in Estonia in a stand of Pinus nigra in Järvselja (South-Eastern Estonia). The fungus was then detected on native Scots pines (P. sylvestris) in several young plantations in the south of the country. During the autumn 2007, M. pini was found on one P. ponderosa tree and on several ornamental P. mugo and P. sibirica trees which were severely affected. During the first year of observations in Estonia, only the anamorph stage was observed. This is the first report of M. pini in Estonia.
The situation of Mycosphaerella pini in Estonia can be described as follows: Present, first detected in 2006, found in Southern and South-Eastern parts in forest plantations and ornamental Pinus trees.
