Between 1999 and 2001 the cultivation suitability of 12 varieties of Kentucky bluegrass (Poa pratensis L.) has been tested at four experimental sites in Switzerland. Of the six new varieties included in the test only Pegasus got on the Swiss list of recommended varieties of forage crops. Pegasus had the highest dry matter yield of all tested varieties. It also showed markedly better values for rust resistance, competitive ability, persistence as well as for juvenile growth than the average of the varieties that are already on the list. Even though the varieties Compact, Monopoly and Leikra had index values below the threshold for recommendation, they will remain on the list in order to guarantee the supply of Kentucky bluegrass seed for the Swiss market.
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.
