From 2015 to 2017, a total of 23 varieties of cocksfoot (Dactylis glomerata L.), 11 of which were new varieties, were tested on seven Agroscope sites as to their suitability for use under Swiss growing conditions. The varieties were evaluated according to yield, feed digestibility, vigour, juvenile development, competitive ability, resistance to leaf diseases, winter-hardiness and persistence. Vigour, digestibility and persistence were double-weighted. Of all the new varieties tested, only the medium- late variety «RGT Lovely» met the requirements for recommendation, achieving the best results among the varieties tested for yield, competitive ability and winter-hardiness. It also performed superbly in terms of persistence and resistance to leaf diseases. Despite its good agronomic qualities, the alreadyrecommended variety «Lazuly» will be deleted from the List of Recommended Varieties of Forage Plants, since it clearly no longer meets the requirements in terms of digestibility. It may therefore only be used as a recommended variety until the end of 2020.
Tuta absoluta is one of the most destructive pests of solanaceous crops. Agroscope has developed a statistical model to study the population dynamics of the pest and its parasitoids and allows interventions to be optimally planned.
Swiss vineyards are often small and arranged in a mosaic of separate plots and management practices. Therefore, it can be assumed that spray drift from conventional to organic vineyards occurs regularly. Nevertheless, no pesticide residues are detected in most organic wines.

Red clover is one of the most important legumes in European forage production. In a multi-year field trial, researchers tested Europe’s largest collection of different red clover accessions at five European locations.
