Since 2009 agricultural data are collected within the framework of the project Farm Accountancy Data Network Agro-Environmental Indicators (AEI FADN). The indicator «pesticide usage» consists of key figures characterizing the practice of chemical plant protection. The crop specific number of spray rounds quantifies both the total number of times a crop has been treated, and also the number of treatments according to the major pesticide group. While there is a substantial regional variability, the mean number of spray rounds seems relatively stable. Differences to earlier surveys are minor, except in the case of oilseed rape. Although the survey currently covers only 1% of the area used for crop production in Switzerland, there is a fair agreement between the projected usage and the sales in the case of frequently used active ingredients. The estimates are uncertain for orchards and vines. In the case of vegetables there are not sufficient data available. In order to assess the potential environmental impacts, an ecotoxicological risk indicator based on the pesticide usage data is currently developed.
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.
Adapted and high-yielding varieties of forage plants are important for Switzerland as a grassland country. Hybrid ryegrass is a versatile forage grass that, thanks to breeding advances, has become even more persistent, disease-resistant and high-yielding over the past 30 years.
