European Corn Borer Certification Program


European Corn Borer (Ostrinia nubilalis) is a destructive pest of many plants and crops. Several states have European Corn Borer quarantines in effect to help prevent the spread of this insect to their state. It can be found in pieces of stalks, cobs, and stems of 1/2 inch or larger in diameter. In order to exclude the borer, all corn, sorghum, broom corn, and sudangrass grains shipped to states with a European Corn Borer quarantine must be scalped (screened) over a 1/2 inch screen.

The NDA Entomology Program helps facilitate the shipment of these quarantined products by issuing annual licenses for certification of screening facilities. Each shipment of regulated commodities to quarantined areas must also be accompanied by a completed European Corn Borer certificate. The following areas have a European Corn Borer quarantine in effect and require shipment certification: Arizona, California, Hawaii, Idaho, Nevada, Oregon, Texas, Utah, Washington, and the Canadian province of British Columbia.
