“The cultivar LARUS is listed in Switzerland since 1998, in Germany since 2000 and in France since 2001. It has been developped from breeding material similar to the one from which TEMARA had been selected, obtained by treating Swiss “”Mattenklee”” (a local, persistent form of cultivated red clover) with colchicine. LARUS provides high, stable yields over three years of cultivation (seeding year, 1st and 2nd harvest year). As compared to TEMARA, LARUS is distinguished by an even markedly better persistence. LARUS is little affected by Sclerotinia crown rot and southern anthracnose (Colletotrichum trifolii). This resistance enables the clover to maintain the desired proportion in grass-clover leys for the entire duration of their existence. Moreover, LARUS is quite resistant against mildew (Erysiphe polygoni), a fungal pathogen which can diminish the quality of diseased forage.”

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.
