摘要：In Styria, especially in the districts of Bruck/Mur, Mürzzuschlag,
Weiz, Hartberg and Graz, symptoms of damage
were observed in larch stands in the vegetation
period 2009. By means of studies under natural and
laboratory conditions, the causal agent was identified
as the Larch needle-cast Mycosphaerella laricina. This
disease is also spreading in other Federal Provinces
(Upper-, Lower Austria, Burgenland). Other damaging
factors such as needle cast Hypodermella laricis were
also reported.
