In the years 1998 until 2000 the two research stations Zürich-Reckenholz and Nyon-Changins tested 71 varieties of perennial ryegrass (Lolium perenne L.) under our growth conditions. Considerable progress was observed in agronomically relevant properties like competing ability, persistence and resistance to bacterial cancor and rust.<br><br>Based on the achieved results the following varieties are recently recommended for cultivation:<br><br>Early to intermediate varieties: Aruga, Aberkite, Arvella, Lipresso, Marmota and Salamandra<br><br>Intermediate to late varieties: Premium, Vercade, Alligator, Calibra, Fetione, Proton, Acento and Barmetra.

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.
