First report of Mycosphaerella pini in Hungary
Regular surveys are being carried out in Hungary in black pine (Pinus nigra) stands, mainly to study the spread and biology of Sphaeropsis sapinea which can destroy young shoots and needles. However, unusual symptoms were observed and laboratory studies showed that they were caused by Mycosphaerella pini (EU Annex II/A2) and by Sclerophoma pithyophila. This is the first time that these two pathogens are observed in Hungarian black pine stands.
