The thesis presents fungi and Phytophthora spp. found on true fir (Abies spp.) in nursery, Christmas tree, bough and landscape plantings in Norway during 2000-2009. Several soil borne organisms were causing root and butt rots, with Phytophthora spp. being the most serious. Fortunately, Phytophthora spp. are so far not widespread on fir in Norway, but they can be disastrous where established. In 2004, P. cambivora was isolated from noble fir (A. procera), P. megasperma from subalpine fir (A. lasiocarpa), and a Phytophthora sp. most similar to P. inundata from Nordmann fir (A. nordmanniana). In 2009, a Phytophthora sp. was isolated at one new subalpine fir Christmas tree location. Many airborne fungi, representing several genera, caused foliar, shoot, and stem diseases; Botryotinia fuckeliana, Cytospora sp., Delphinella abietis, Herpotrichia parasitica, Melampsora abieti-capraearum, Neonectria sp., Phaeocryptopus nudus, Phomopsis spp., Pucciniastrum epilobii, Rhizosphaera kalkhoffii, and Sydowia polyspora. The pathogenicity of Camarosporium, Camarographium, and Pestalotiopsis funerea is uncertain. Aslo two organisms that are not considered pathogenic are presented, but they commonly appear on fir; Cladosporium sp., and Thysanophora penicillioides. Several of the presented organisms are new to the fungal flora of Norway.

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.
