Two new cultivars of Italian ryegrass have been released frequently: Lipurus and Vicugna. These tetraploid cultivars originate from the same breeding stock as the well-known varieties Lipo and Ellire. They are distinguished by an improved resistance against important diseases whilst maintaining the high yield level of Ellire. Mainly resistance against bacterial wilt <br>( Xanthomonas campestris pv. graminis) has been improved by selection after artificial infection. The seasonal distribution of yield differs from Ellire by a greater yield of the first cut in spring and a slightly inferior productivity in summer.
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.
