It’s often called the billion-dollar beetle. That’s because corn rootworm (CRW) pressure has been known to cause U.S. farmers up to $1 billion in control costs and yield loss annually.

For those with affected or at-risk fields, a critical component of any management plan is using defensive CRW trait technology, then partnering traits with a combination of best management practices (BMPs) to help maximize and prolong the life of CRW trait technology.

No magic bullets for this beetle

Matt Essick, Pioneer Agronomy Manager, offers insight on what makes this insect such a menace to fields across the Corn Belt, and advice on how to better manage it.

“Corn rootworm has proven over time to be very adaptive, and I'd say there’s no magic bullet — there’s no one trait that can eliminate this pest problem from your field,” Essick said. “Trait effectiveness could be anywhere from three to five years to as long as 20 plus years. But if we also implement best management practices, our research shows that can extend the trait life by at least 30%, and up to 50%.”

According to Essick, research data supports growers choosing an integrated approach with multiple tactics to improve the durability and effectiveness of CRW products. Using crop rotation and/or in-season adult insecticides can reduce eggs in the soil for the following season. Altogether, it resets populations to the point where the pest can be managed, while helping to extend the life of today’s advanced CRW traits.

Pioneer® brand Qrome® products offer growers a robust defensive trait technology with two modes of action to control CRW. That protection is coupled with exceptional agronomic performance – like strong emergence, disease tolerance and standability – enabling Qrome products to deliver a 6-8 bu/A yield advantage over competitive SmartStax® technology since being widely introduced in 2019.1

“It comes down to using multiple methods to minimize buildup, followed by continuously evaluating your management practices over time,” Essick said.

Growers can collaborate with their local Pioneer agronomist and sales representative to develop integrated management plans, including selecting the right trait technology for their CRW acres.
