The Handy Bt-Trait Table for U.S. Corn Production
Joshua Putman, Field Crops and Forage Specialist
Southwest New York Dairy, Livestock and Field Crops Program

2021 marks the 25th year of commercialization of Bt corn in the United States. The first Bt corn hybrids helped producers control European corn borer, but Bt has come a long way since then. Bt hybrids are now planted on greater than 80% of U.S. corn acres. The benefits of widespread use of Bt hybrids include a reduction in corn borer in the landscape (benefitting conventional corn & vegetables too), and an overall reduction in insecticide use. Producers in SWNY are reviewing seed catalogs to purchase the best corn hybrids for their operation. Some acres in the region are continuous corn and would warrant the need for protection against certain pests such as corn rootworm. This PDF document provides information about the trade names, primary insect targets, and herbicide tolerances for each product. If you have questions about corn traits or placement, contact Josh Putman at 716-490-5572 or jap473@cornell.edu.
