A new report from the Center for Science in the Public Interest (CSPI) in Washington, D.C. has found that a significant number of growers who plant genetically engineered (GE) corn are failing to comply with requirements for maintaining 'refuge acres' - non-GE corn planted to help prevent insect resistance.

Why it matters

Refuge acres are a critical part of insect-resistance management strategies for GE crops, helping to preserve the long-term effectiveness of these technologies. Widespread non-compliance could lead to the development of resistant insect populations, undermining the benefits of GE crops for farmers.

The details

According to CSPI staffers, one out of every four growers who plants GE corn is failing to comply with at least one important insect-resistance management requirement. These refuge acre rules are intended to maintain populations of susceptible insects that can interbreed with any resistant insects, preventing resistance from spreading.

What’s next

The report's findings are likely to prompt increased enforcement and education efforts by agricultural regulators to ensure growers comply with refuge acre requirements for GE corn.

The takeaway

Widespread non-compliance with refuge acre rules for GE corn poses a serious risk to the long-term effectiveness of these important pest management tools. Stronger oversight and better education for growers will be needed to address this issue.
