Genetic diversity – the variety of genes and alleles within a species – constitutes the most basic level of biodiversity, and is an important prerequisite for productivity and sustainability in agricultural production systems. We have developed and applied various methods to determine genetic diversity on farms in Europe, Ukraine and Uganda. A questionnairebased survey conducted on a total of 203 farms has shown that the genetic diversity of crops and livestock varies greatly between different regions, and depends upon the prevailing production systems. In order to obtain a more accurate insight into the genetic diversity of grassland, we studied 60 populations of orchard grass from Bulgaria, Norway and Switzerland with molecular genetic markers. In doing so, we learned that although this species exhibits a very large variability within the populations, the differences between the populations tend to be minor.
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.
Swiss vineyards are often small and arranged in a mosaic of separate plots and management practices. Therefore, it can be assumed that spray drift from conventional to organic vineyards occurs regularly. Nevertheless, no pesticide residues are detected in most organic wines.

Red clover is one of the most important legumes in European forage production. In a multi-year field trial, researchers tested Europe’s largest collection of different red clover accessions at five European locations.
