Welcome Help from Coragen® to Control Sweet Corn Earworm Pests
DuPont™ Coragen® insecticide is the product you can count on for effective control of earworm pests that infect sweet corn. It delivers reliable and consistent protection against major worm species including European corn borer, Western bean cutworm and corn earworm — even resistant biotypes. It’s also classified as a reduced risk insecticide, having minimal impact on beneficial insects and pollinators when applied at label1.
Control at multiple stages
Coragen® is effective at multiple stages of the life cycle which means more flexibility in timing your application and better overall protection. The rapid cessation of feeding, residual activity and excellent rainfastness associated with Coragen® deliver long-lasting plant protection. It is particularly potent against larvae as they hatch from the eggs (ovi-larvicidal activity), but also provides excellent control at the ovicidal and larvicidal stages.
Innovation means better protection
Resistance to existing chemistries is a concern because many insects have multiple generations, resulting in multiple insecticide applications to protect the crop. Coragen® fits well in an IPM system because the active ingredient, Rynaxypyr®, comes from a whole new class of chemistry – Group 28, the Anthranilic diamides. Coragen® even protects against biotypes that are resistant to pyrethroid and carbamate insecticides.
Plan ahead thanks to new registrations
Until now, sweet corn growers and processors have had to wait for an emergency registration before they could use DuPont™ Coragen® insecticide. Now that sweet corn has been permanently added to the Coragen® label, growers can plan on having the product available when insect infestations hit.
The right choice for European corn borer
Residual European corn borer control means that the plant is protected for a longer period of time than with contact-only insecticides. Coragen® often replaces two or three applications of other popular treatments.
How to apply
Time the applications to coincide with peak egg hatch. Scout by monitoring egg laying and egg hatch to determine application timing. Thorough coverage is essential for optimum protection.
1In line with Integrated Pest Management and Good Agricultural Practices, insecticide applications should be made when pollinators are not foraging to avoid unnecessary exposure.
