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.

The root knot nematode (RKN) Meloidogyne incognita causes damage in field and greenhouse crops. Agroscope researchers have developed a new screening test to identify bacteria that antagonise this agricultural pest.
With CULTAN fertilisation, nitrogen is injected into the soil as an ammonium solution. Multi-year trials conducted by Agroscope show that this method reduces nitrogen leaching by an average 38% without negatively affecting yields.
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.
