摘要：New results are presented on taxonomic position,
pathogenicity and control of the needle cast fungus
Kabatina abietis, a species causing economic losses in
Christmas tree production in various European countries
as well as in Northeast USA. Trials with copper
fungicides conducted in 2008 in Denmark, Norway,
Germany, Austria and USA against Kabatina abietis
were unsuccessful. Though the identity of Kabatina
abietis with Sydowia polyspora as well as its pathogenicity
was confirmed by a thesis in Norway, it
remains unclear, whether the characteristic needle
symptoms could be the result of different damaging
agents.
