When exposed to stress, plants produce protective compounds. These molecules contribute to their adaptation to environmental changes and to resistance to microbial attacks. Some fungal phytopathogenic species, especially those belonging to the Fusarium group, are also able to develop diseases in humans. In order to identify new sources of antifungal molecules of pharmacologic or agronomic interest, around thirty plant species from different taxonomical groups have been exposed to UV-C. Plant species from the Vitaceae group respond to UV treatment with the induction of a strong anti-fusaric activity

Five Merlot clones bred in Switzerland are currently being distributed by the certification sector. A multiyear trial conducted by Agroscope in Gudo (Canton of Ticino) has made it possible to compare them with French and Italian reference clones and to highlight their very good performances.
Arbuscular mycorrhizal fungi are important for healthy soils and crops. A pan-European study shows that plant-protection products adversely affect these fungi, reducing their ability to supply plants with phosphorus via their roots.
Birdsfoot trefoil and sainfoin are used in mixtures for perennial hay meadows and for tannin-containing fodder. Agroscope is adding two new cultivars of birdsfoot trefoil to the ‘List of Recommended Varieties of Forage Plants’, whilst there is no change in the case of sainfoin.
