After a long battle with corn rootworm, Midwest farmers thought they'd found relief in genetically modified seeds engineered to produce toxins deadly to the pest. But recent research confirms what ...

The results from a couple of field surveys that were conducted recently across the area have been released. We've been surveying for two insect pests for a number of years to give producers an idea of ...

AMES — Western corn rootworm resistance to Bt corn is increasing, and if farmers hope to maintain Bt traits as tools, they need to diversify their management, said Aaron Gassmann, Iowa State ...

An analysis of data covering 12 years and 10 U.S. Corn Belt states reveals that farmers suffer economic loss from the over-application of genetically engineered corn designed to combat rootworm pests.
