Co-existence measures for Mexican maize work

Mexican researchers from five universities and colleges have concluded that co-existence between the planting of conventional and genetically modified maize is possible. They carried out research on gene flow in maize and found that co-existence measures can be implemented in Mexico to minimise the spread of pollen. They found that cross-pollinisation levels fall below 1% at 16 m distance, and to 0.5% at 20 m. At distances beyond 20 m, outcrossing values at all locations were below 1%, the researchers state. The study was carried out in the six economically principal Mexican states for maize hybrid cultivation in 2011-13. The study suggests that co-existence measures such as minimum spatial isolation would be successful if adopted across Mexico. The findings of the study have been published in the journal, Plos One.
