Between 2002 and 2004, Agroscope FAL Reckenholz and RAC Changins tested four varieties of tall oat-grass (Arrhenatherum elatius L) and four varieties of golden oat-grass (Trisetum flavescens L.) at five and seven experimental sites respectively. The varieties were compared for yield, juvenile development, vigour, disease resistance, winter hardiness and competitive ability. With golden oat-grass the adaptation to higher altitudes was also accounted for. An index value was calculated from the data, allowing for a direct comparison of the tested varieties. According to the results, the new variety of tall oat-grass Arone is recommended. With golden oat-grass, Gunter will be newly added to the «List of Recommended Varieties of Forage Plants».
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.
