Modified wood has potential for above ground use, but surface treatment might be a request in such applications. Three coating systems were applied on furfurylated Scots pine, acetylated Scots pine, heat treated Scots pine, oil heat treated Scots pine, heat treated Norway spruce, and eight reference wood substrates and exposed outdoors to evaluate their ability to resist surface mould. Samples of the surface were taken for fungal identification to examine any relationship between treatment and fungal species. Both water-borne and solvent-borne coatings with various fungicides were included and the test was carried out according to EN 927-3. The degree of mould growth mainly varied with time and type of paint. Of the modified wood substrates furfurylated Scots pine had the lowest degree of mould growth and acetylated pine had the highest after 3.5 years. A brown semi-transparent acrylic paint had the lowest degree of mould growth after year 1, year 2.5 and year 3.5. Larch heartwood, copper-organic preserved pine and pine heartwood performed best as wood substrates. No differential patterns in susceptibility to various fungal species were detected on the surface of the coated wood substrates Aureobasidium pullulans was the dominating species on all the wood substrates.

Representative European wheat cultivars were tested under quarantine containment for their susceptibility to Tilletia indica, the cause of Karnal bunt of wheat. Fifteen winter and 15 spring wheat (Triticum aestivum) and 11 durum wheat (Triticum durum) cultivars were inoculated by boot injection just prior to ear emergence to test their physiological susceptibility. Selected cultivars were then re-tested by spray inoculation after ear emergence to determine their morphological susceptibility, which is a better predictor of field susceptibility. At maturity, the ears and seeds were assessed for incidence and severity of disease. For the physiological susceptibility tests, 13/15 winter wheat cultivars were infected and the percentage of infected seeds ranged from 1 to 32%. For spring cultivars, 13/15 cultivars were infected and the percentage of infected seeds ranged from 1 to 48%. For the durum cultivars, 9/11 were infected and the percentage of infected seeds ranged from 2 to 95%. Across all cultivars, 35/41 were infected. Based on historical Karnal bunt susceptibility categories using coefficients of infection, one cultivar was classed as highly susceptible, three as susceptible, 11 as moderately susceptible, 20 as resistant and only six as highly resistant. The spray-inoculation morphological susceptibility tests broadly confirmed the physiological susceptibility results, although lower levels of infection were observed. Overall, the range of susceptibility was similar to that found in cultivars grown in Karnal bunt affected countries. The results demonstrate that European wheat cultivars are susceptible to T. indica and thus could potentially support the establishment of T. indica if introduced into Europe.

Det blir sagt at før fans det to slag potet i Valdres. Det var svarteplo og (kvit)eplo. Kvar det har vorte av det kvite slaget veit me ikkje. Men den svarte blir fortsatt dyrka i Valdres, men mest som hobby. Skalet på poteten er nærast plommefarga med lyse spetter i. Formen er rundoval og noko ujamn med relativt djupe grohol. Når me skjer over poteten ser me at det omtrent 1 cm frå skalet er ein fiolett ring. Fargestoffet er anthocyanin, same stoffet som ein finn i blåbær. Svart Valdres gir god avling , men den lir av det same som dei fleste eldre sortar som til dømes Mandel: den er svak mot sjukdom og spesielt turrote. Dei siste åra har etterspørsel en etter fleire av dei gamle potetslaga auka. Mandelpotet er svak mot sjukdom og gir låge avlingar, men på grunn av den store etterspørselen og omdømmet som gourmetpotet, kan produsentane få ein brukbar pris. Gullauge frå Nord-Norge og Ringerikspotet er andre gamle lokale spesialsortar. Med rett marknadsføring skulle det ikkje vere noko i vegen for å lansere Svart Valdres som Valdres sin eigen gourmetpotet. Så får me håpe nokon har tid og interesse for å dyrke denne poteten.

Svartskurv kan gi mange ulike symptomer i potet. Et av disse er vekstsprekk i knoller.

Due to a late harvesting season compared to that found in other European countries, the sweet cherry industry in Norway is now expanding, aiming for export markets. Cultivars producing high quality fruit that ripen late (late July and throughout August) and that are suitable to grow in high density production systems are sought. In addition, early ripening cultivars are sought for local marketing in early and middle July. Testing cultivars and advanced selections has been carried out at Ullensvang Research Centre since 1959. During the last decade, 130 cultivars and advanced selections have been included in the testing program. Important parameters like fruit size, fruit firmness, low fruit cracking, high and precocious yield, fresh appearance and good flavour have been evaluated. Based on the results from this testing program, the following cultivars are currently recommended: a) for early season: `Burlat", `Moreau" and `Merchant", b) for mid-season: `Giorgia", `Chelan", `Samba", `Techlovan" and `Van", c) for late season: `Lapins", `Kordia", `Regina" and `Sweetheart".
