Between 2000 and 2002 the Swiss Federal Research Stations for Plant Production at Changins (RAC) in Nyon and for Agroecology and Agriculture (FAL) at Reckenholz in Zurich conducted comparative trials with 32 varieties of cocksfoot at five experimental sites. Based on measurements and observations of yield, persistence, competitive ability, disease resistance and digestibility of organic matter (DOM) an index-value was calculated allowing for an accurate comparison of the varieties. The following varieties have been newly accepted in the Swiss «List of Recommended Varieties of Forage Plants»: Barexcel, Geenly, Foly and Quantum.
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.
