Can GM conventional and organic crops coexist?

Yes. In Europe, for example, over 10 years of experience with Bt maize in Spain has shown that farmers can and do manage coexistence in practice – just as coexistence between conventional and organic farming has been managed for decades To guarantee non-problematic coexistence, farmers need to apply simple good farming practices, such as rotations, resistance management, isolation distance and rows, planting near other crops, etc. A labelling threshold of 0.9% has been set for GM content in conventional and organic crops, as long as growers have demonstrated that they have taken reasonable precautions to prevent inter-mixing.
