Study: High-tech Corn Cuts Pest Damage Far Afield

posted on October 7, 2010

MINNEAPOLIS — New research finds that corn genetically engineered to resist insects also helps out non-modified corn growing nearby.

Researchers writing in the journal Science call it the "halo effect."

It turns out that since insects that attack the modified corn die, there are also fewer of them to attack other corn plants.

Corn borers have cost American farmers more than $1 billion in damage in some years.

The researchers calculated that the altered corn has produced an economic benefit of $6.9 million during the past 14 years in five Upper Midwest corn-producing states.
