Between 2001 and 2003 Agroscope FAL Reckenholz and RAC Changins, the federal research stations, tested 19 varieties of meadow fescue and 13 varieties of red fescue. The varieties were compared in yield, juvenile development, vigour, persistence, disease resistance, competitive ability and adaptation to higher altitudes. With red fescue the winter hardiness was also accounted for. An index value was calculated from the data, allowing for a direct comparison of the tested varieties. The following varieties of meadow fescue obtained the minimum index value necessary for recommendation: FP 6, FP 7 and FP 8. These varieties have yet to fulfil the legal obligations concerning their commercialisation so that they can be made eligible for entry onto the «list of recommended varieties of forage plants». None of the tested new varieties of red fescue reached the index value that is required for recommendation.
Herbicide-resistant weeds are a growing problem throughout the world. Monitoring herbicide resistance in Switzerland allows us to understand the mechanisms behind it and to better manage the use of herbicides.
Agroscope compared crop protection strategies in apple production. Reducing the use of plant-protection products lowered the local ecotoxological risks, but resulted in trade-offs between environmental and economic performance.
Bacillus thuringiensis (Bt) bacterium proteins protect Bt maize from being fed on by specific insects. A new, systematic analysis of international field data confirms that non-target organisms in Bt maize are largely spared.
