Fruit and wine producers who receive information from the public sector are more likely to use preventive measures such as nets or hygiene measures to combat spotted-wing drosophila. Producers advised by private firms that sell plant-protection products are more likely to use synthetic insecticides.

Digital technologies are fixed features of modern agriculture – but to what extent are they already being used in Switzerland? A survey conducted by Agroscope provides answers to this question. Digital technologies reduce the physical workload of farming and contribute to sustainable field management. They also enable optimised management decisions based on plant- or soil-related…

From 2016 to 2018 inclusive, Agroscope tested 54 varieties of red clover (Trifolium pratense L.) at six locations. Of these, 25 were new varieties and 29 were already-recommended varieties that were being retested. Yield, vigour, juvenile development, resistance to leaf diseases and anthracnose, winter-hardiness and persistence were all evaluated. For the persistent “mattenklee” type, the…

Drosophila suzukii is an invasive species recently introduced in Europe and causing damages to fruit production. Trichopria drosophilae is considered one of the most suitable indigenous parasitoid to be used in biocontrol programs against D. suzukii. To characterize genetic variability and the spatial genetic structure of populations of T. drosophilae, we developed 21 species-specific molecular…

The Swiss Federal Government’s agricultural policy aims inter alia to provide agricultural ecosystem services, reduce environmental impacts, and increase the resilience of the agricultural sector. Combining the cultivation of trees with crops or grass – termed «agroforestry » – can contribute to achieving these goals without substantially limiting agricultural production. We identified the regions where…

Interest in buckwheat production has been growing for several years now in Switzerland. Previously, this field crop had almost completely been forgotten. Since it is not related to other arable crops, buckwheat is ideal for breaking up crop rotations. It is also interesting from a nutritional point of view, as it contains zinc and selenium,…

Growing a mixture of silage maize and runner beans could be an alternative to conventional silage-maize cultivation. The beans use the maize plants as a support, and are expected to increase the protein content of the maize silage. The question, though, is how yield and content of other substances change when the two crops are…

The practice of sowing companion crops (or «service plants») in among oilseed rape began to get off the ground in Switzerland several years ago. Certain farmers see companion cropping as an innovative technique allowing them to cut back on the use of plant-protection products, and in particular enabling them to forgo the use of herbicides,…
