The 10th Meeting of the Panel on Efficacy Evaluation of Herbicides and Plant Growth Regulators took place at the Research Station Agroscope Changins-Wädenswil ACW, in Nyon, Switzerland, on 2011-03-15/16, at the kind invitation of Mr Bohren. The Panel was welcomed by Dr Jean-Philippe Mayor who gave a brief overview of the Agroscope organization and its main tasks.

Many thanks are due to Mr Bohren who provided most excellent organizational support and arranged an interesting visit of the lovely old town of Nyon. Participants also had an opportunity to visit the premises of the Research Station.
