Cold-fogging crop protection products in greenhouses is an easy to handle and time and labour saving method. However measurements of depositions on commercial tomato and eggplant crops in two greenhouses in Switzerland revealed that active ingredients distribution in the greenhouses was very uneven. Furthermore there were spots where unacceptably high residues were found on harvested fruit. Cold-fogging application method must and can be improved through technical measures. The choice and the dosage of the products should rely on solid data sets made available to the extension service.
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.
Tall oat grass and golden oat grass are typical hay-meadow grasses that are also suitable for forage mixtures. Of the four tall and three golden oat grass varieties tested, only one new variety of tall oat grass is likely to make it onto the List of Recommended Varieties.

FiBL and Agroscope investigated bread wheat varieties to determine their yield and quality stability. The results show that the choice of variety must be adapted to the site and that high yield potential does not go hand-in-hand with a high protein content.
