The effects of soil conditions and cultural control methods on development of skin blemish diseases were studied in three different field experiments during two years. All studies included the cultivars Saturna and/or Asterix. Experiment 1 included effects of fertilizers and soil compaction, mainly on Streptomyces ssp (common scab), while experiment 2 studied effects of soil humidity on various skin blemish diseases. Experiment 3 studied effects of harvest, curing and storage strategies on silver scurf (Helminthosporium solani), but also on powdery scab and black scurf.

In Norway, most lambs are slaughtered at the end of the grazing season in September. An increased demand for fresh meat during the off-season may change this pattern. Castration of male lambs is not permitted, and off-season slaughtering may affect the acceptability of the meat. The objective of this study was to determine the effect of gender and the interaction between gender and diet on meat quality from Norwegian White Sheep lambs slaughtered in September. In two different experiments, 22 and 29 males compared with 22 and 46 female lambs, respectively, were used. Loin samples of M. Longissimus dorsi were analysed for sensory profile and fatty acid composition. Meat from male lambs in Experiment 2 had higher scores for cloying and rancid flavour, and lower scores for sour and sweet taste compared to meat from female lambs. It is concluded that even at the normal slaughtering time in September, significant differences between genders may occur.

In Norway log buildings are normally produced from logs canted on two sides. The canted faces are prone to crack formation during drying. This can cause some disadvantages, e.g. the cracks can trap water from rainfall, because the canted faces form the wall surfaces in the log buildings.

Strawberry production in high plastic tunnels is becoming popular for the advantages of extended production and reduced disease problems. However, this production system creates favorable conditions for several pests, including the two-spotted spider mite (Tetranychus urticae) and for some diseases, of which powdery mildew (Podosphaera aphanis) is the most important. Preliminary laboratory experiments were conducted to study: (1) the preference of T. urticae to mildew infected vs. healthy strawberry leaves, and (2) the impact of powdery mildew on T. urticae egg production and predation of the predatory mite Phytoseiulus persimilis. Five days after the mite release, the total number of T. urticae eggs and nymphs found on healthy leaf discs were two times higher than on leaf discs with powdery mildew, predatory mites or both. In the preference experiment, a significant number of T. urticae moved to healthy strawberry leaf discs and settled there for the whole period of the experiment. The results indicated that T. urticae did not thrive on strawberry leaves heavily infested with powdery mildew, and that powdery mildew seemed to reduce the predation efficiency of P. persimilis. Therefore, it may be economical and efficient to control powdery mildew before releasing P. persimilis to control the spider mites.
