Between 1995 and 1997, 38 varieties of red clover and 24 of meadow fescue have been evaluated in a comparative variety test program. The criterias looked at were properties as yielding ability, competitive ability, resistance to diseases and persistence. Based on the achieved results, the following varieties are newly considered for the <<List of Recommended Varieties of forage Plants>): long duration red clover Corvus (2n), Pica (2n), Larus (4n) Astur (4n), short duration red clover Tedi (4n), Maro (4n), Sigord (4n), meadow fescue Pradel and Cosmolit.
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.
