German research OKs GM (genetically modified) crop co-existence:
A 20 m buffer zone between adjacent fields is "sufficient" to prevent contamination of conventional maize by genetically modified lines, researchers at the German Martin Luther University say. They conducted over 30 field trials to show that transgene levels in conventional maize grains can remain below 0.9% during co-existence. The 0.9% level is the threshold for labelling GM products in the EU. The scientists planted Bt maize in the middle of 0.3-23 ha fields surrounded by conventional crops with overlapping flowering. Sampling of the crops up to 60 m from the GM maize found that no samples beyond 10 m contained GM material above the threshold. The trials demonstrate that co-existence is "possible", the International Service for the Acquisition of Agri-biotech Applications comments.
