In the certification of organic wheat seed, the required germination capacity is often not achieved. This is frequently due to excessively high infestation with the snow mould pathogen Microdochium nivale. A warm-water treatment effectively controlled infestation on the seed. Owing to the high expenditure of energy for redrying, however, this method has not caught on in practice. Dressing with the bacterial product Cerall® is only partially successful in controlling seed infestation with M. nivale. In a laboratory screening with various plant-based products, a preparation (‚B‘ ) showed a good inhibitory effect on the mycelial growth of M. nivale. Moreover, in several in vivo trials in the climate chamber and in field trials, the treatment of seed with powder from the preparation ‘B’ demonstrated significant effects. The compound not only improved seedling emergence, but reduced also yield losses. The challenge is to develop the formulation to the point where the preparation ‚B‘ can be used as a product in large-scale dressing.
Tall oat grass and golden oat grass are typical hay-meadow grasses that are also suitable for forage mixtures. Of the four tall and three golden oat grass varieties tested, only one new variety of tall oat grass is likely to make it onto the List of Recommended Varieties.

FiBL and Agroscope investigated bread wheat varieties to determine their yield and quality stability. The results show that the choice of variety must be adapted to the site and that high yield potential does not go hand-in-hand with a high protein content.
Adapted and high-yielding varieties of forage plants are important for Switzerland as a grassland country. Hybrid ryegrass is a versatile forage grass that, thanks to breeding advances, has become even more persistent, disease-resistant and high-yielding over the past 30 years.
