Sloppy Seed Sorting Main Culprit in GM Crop Escapes

A study has discovered that careless handling of seeds may be the key reason for the unintended spread of genetically modified (GM) crops.

Currently, stands of non-GM crop plants are typically planted near fields of GM crops to prevent pests from developing resistance to the pesticides used on the GM plants. But human error could undermine this strategy.

SciDev Net reports:

"... [P]oor seed-sorting resulted in some seed bags intended for planting in non-GM fields containing as much as 20 per cent GM seed. One non-GM field was found to have a large number of GM plants due to human error in planting."
