In 2007, the GM potato Amflora was cultivated on nearly 450 ha in Germany. The goal of the “field trial” as to produce seed potatoes just in case Amflora would be allowed for commercial cultivation. But another result now becomes quite obvious: GM potatoes cannot be kept under control and they cannot be cleared off the field completely. In summer 2008, despite repeated controls Amflora potatoes are happily growing on the field.
