This review follows the historic development of viticulture in Eastern Switzerland. It is not clear, whether wine making in this area dates back to the Romans. Written proof concerning local vineyards is available from the the 9th century on mainly from monasteries, which were instrumental in propagating viticulture. Later vineyard area grew rather uncontrollably and expanded into climatic regions and heights which were definitely not suited for grape-growing, even if allowance is made for a warm climatic spell in the Middle Ages. Geographic extension of grapevines in the eastern part was maximal at 1875. Changes, which include climatic deterioration, occurrence of new grape pests and diseases (phylloxera, downy and powdery mildew), poor wine quality and import, due to improved railroad connections, induced all but a total collaps of local viticulture. The actual vine growing area of the German speaking part of Switzerland now amounts to about 2500 ha. Factors responsible for this viticultural crash are evaluated with respect to their bearing on modern Swiss viticulture.

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.
