From 2016 to 2018, Agroscope tested a total of 23 varieties of meadow fescue, including 16 new varieties, in comparative variety trials at six locations. The varieties were assessed on the basis of systematic examinations and observations of forage yield, vigour, juvenile development, competitive ability, persistence, tolerance to winter influences, resistance to leaf diseases, digestibility of organic matter and suitability for higher altitudes. Two new varieties achieved results that allow them to be included in the «List of recommended varieties of forage plants»: FP 0945 and Cosmopolitan. They are recommended as soon as they meet the legal requirements for tradability. Currently this is only the case for Cosmopolitan. All the previously recommended varieties will retain their recommendation until further notice.
Bacillus thuringiensis (Bt) bacterium proteins protect Bt maize from being fed on by specific insects. A new, systematic analysis of international field data confirms that non-target organisms in Bt maize are largely spared.

A natural antagonist of Drosophila suzukii, a parasitic wasp from its native range, is harmless to the native non-target species Drosophila melanogaster. This has been proven in trials in secured field cages in Switzerland.
