SmartStax PRO®: All-In Corn Rootworm Defense

SmartStax® PRO with RNAi Technology protects against corn rootworm, European corn borer, southwestern corn borer, fall armyworm, black cutworm and corn earworm.

Yes, SmartStax PRO still works in fields with a history of Bt-resistant corn rootworms. RNAi Technology works alongside existing Bt proteins for a total of three active ways to fight corn rootworm. 

Exposure to the same Bt proteins over time can cause trait resistance. Switching up your trait strategy, crop rotation and scouting can help fight resistance.

SmartStax PRO® is designed for fields with moderate to high corn rootworm pressure, including continuous corn acres or fields with a history of rootworm feeding. Before you plant, make sure to review your field history, previous crop rotation, local pest trends and scouting records to understand your risk. Matching SmartStax PRO to the right acres ensures you get the right trait on your operation.

An integrated corn rootworm management program ensures you get the most out of your trait selection. Scout your fields, monitor beetle populations, rotate crops when needed and follow Insect Resistance Management (IRM) requirements. Trait technology works best when paired with good agronomic practices.

SmartStax PRO combines proven Bt trait technology with RNAi Technology to deliver three distinct modes of action against below-ground corn pests. While Bt traits and RNAi both activate when larvae feed on the roots, they control the pest in different ways, giving a layered approach to below-ground defense.
