The flight of the pollen cloud

---

To prevent the uncontrolled spread of GM maize, one needs to know how far the pollen travels. In a project led by the Federal Biological Research Centre, outcrossing rates were measured and a mathematical model developed for pollen drift as a function of climatic conditions. On film: pollen drift simulation

Coexistence of conventional and GM maize cultivation

---

Within the EU, a threshold of 0.9 per cent has been agreed for technically unavoidable GMO contamination. If the GMO level exceeds this threshold, even conventional maize must be labelled as "genetically modified". This means that GM maize cultivation must be organised in such a way that non-GM conventional farming is possible in the long term.

Background

• Coexistence information system
• Focus on coexistence: Studies, research results, policy
• BMELV coexistence research programme 2006. Locations, experimental design, research questions

 

Maize in Mexico

American scientists found GM maize in native varieties. But there was disagreement.
