The evaluation and registration of pesticides, new solutions to urgent problems in minor crops, as well as prognosis and recommended measures services are important requisites for a sustainable vegetable production. The examples of the carrot fly, the cabbage root fly and the cutworm show that research in the field of host-plant selection and sexual behaviour of pest insects can lead to new and efficient tools for the monitoring of their occurrence and density. Serious pest problems arise regularly and create new challenges. The successful solutions for the monitoring of key pests described here may provide clues to promising future research projects.

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.
