In 1998 Plum pox virus (PPV) wasdetected for the first time in Norway. Virus-like symptoms were observed on several trees in a collection ofplum cultivars at Njøs Research Station in the Sogn og Fjordane County in WestNorway. The Norwegian Food SafetyAuthority and the Norwegian Crop Research Institute immediately startedsurveying other variety collections around the country, nuclear stock materialand orchards in all important plum-growing areas. Since 1998 we have surveyed themain part of the commercial plum orchards in Norway. About 75 000 individualtrees have been tested. About 1 % of the trees have been found infected by PPV.Only the PPV-D strain has been found. It is suspected that the main infectionsource was infected plums or apricots imported to Njøs around 1970 or earlier.In most plum orchards in Norway,the spread of PPV by aphids is relatively slow. Therefore, we expect to be ableto eradicate PPV from commercial plum orchards in the near future.The eradication work iscontinuing.

The usage of plant protection products and biocontrol agents in soft fruit production has always been an important subject for the IOBC/WPRS Working Group "Integrated Protection of Fruit Crops" Study Group "Soft Fruits". The usage of pesticides and biological control methods varies considerably between countries and it is very difficult to get a good overview on the range of products that are applied or in development in soft fruits. In order to share and facilitate the flow of information, the Study Group "Soft Fruit" initiated a survey on the availability and usage of active ingredients and biocontrol agents in the different European countries in 2007. First, the most important pests and diseases in strawberry and raspberry production were identified. Then members of the different countries listed available products on the domestic market and indicated their usage in the field. So far 15 countries have contributed to the survey. The received data are accessible on the website http://www.any3.ch/IOBC/Softpest/index.html

The Svalbard Global Seed Vault provides facilities for the safety deposit of samples of seed of distinct genetic resources of importance to humanity, under black box arrangements and in permafrost conditions supplemented by refrigeration in accordance with internationally agreed standards. The Seed Vault was established by the Norwegian Government in 2008 at 78 degrees North in the Norwegian village of Longyearbyen, on Svalbard, the farthest north you can travel in the world on regularly scheduled commercial jet flight. It is managed in a tripartite arrangement between the Norwegian Ministry of Agriculture and Food, the Global Crop Diversity Trust and the Nordic Genetic Resource Center. The last organisation is responsible for the day to day operation and management and organises deposits in the Seed Vault. The Seed Vault offers the most secure back-up possible for a worldwide network of genebanks that together conserve and make available the biological foundation of agriculture. It contains duplicates of collections of all the world’s major seed crops and a huge range of minor crops. The Seed Vault has a capacity of 4.5 million distinct samples. The seeds are stored in “black-box conditions”, meaning that seed storage boxes remain the property of the institution that sent them, and are not even opened by any party other than the depositor. The storage is provided free of charge. At present, there are more than half a million seed samples in the Vault, origination from 212 countries of the world.

Current season needle necrosis (CSNN) has been a serious foliage disorder on true fir Christmas trees and bough material in Europe and North America for more than 25 y. Approximately 2-4 weeks after bud break, needles develop chlorotic spots or bands that later turn necrotic. The symptoms have been observed on noble fir (Abies procera), Nordmann fir (A. nordmanniana) and grand fir (A. grandis) on both continents. CSNN was reported as a physiological disorder with unknown aetiology from USA, Denmark, and Ireland, but was associated with the fungus Kabatina abietis in Germany, Austria and Norway. In 2007, a fungus that morphologically resembled K. abietis was isolated from symptomatic needle samples from Nordmann fir from Austria, Denmark, Germany, Norway, and USA. Sequencing of the internal transcribed spacer (ITS) region of ribosomal DNA of these cultures, plus a K. abietis reference culture from Germany (CBS 248.93), resulted in Hormonema dematioides, the imperfect stage of Sydowia polyspora, and thus the taxonomy is further discussed. Inoculation tests on Nordmann fir seedlings and transplants with isolates of S. polyspora from all five countries resulted in the development of CSNN symptoms. In 2009, S. polyspora was also isolated from symptomatic needles from Nordmann fir collected in Slovakia. (c) 2010 The British Mycological Society. Published by Elsevier Ltd. All rights reserved.
