Since its commercialization in 2003, Bt corn has—and still is—proving to be an important technology for the control of insect pests, higher yield production, and higher quality grain. In recent years, however, the western corn rootworm’s increasing resistance to Bt corn has caused some alarm.

 

Bt resistance has been confirmed to one or more Bt rootworm toxins in Nebraska, Minnesota, Iowa, and Illinois, and scientists in Colorado, Kansas, Missouri, New York, South Dakota and Wisconsin also are reporting significant damage in fields planted to corn hybrids containing Bt rootworm toxins.

 

To help U.S. corn growers and consultants tackle this growing issue, Dr. Robert Wright, Research & Extension Entomologist at the University of Nebraska-Lincoln, organized a seminar comprising five webcast presentations that focus on the many new and changing aspects of western corn rootworm management in the transgenic era.

 

This seminar, titled “Corn Rootworm in the Transgenic Era” is located in the Plant Management Network’s ‘Focus on Corn’ resource, which is co-sponsored by the National Corn Growers Association. All five talks are freely available 24/7 to corn producers, consultants, extension agents, and other practitioners involved with Bt corn and the management of western corn rootworm.

 

‘Focus on Corn’ is a publication of the Plant Management Network, a nonprofit online publisher whose mission is to enhance the health, management, and production of crops through quality, science-based crop management information for agricultural practitioners. To help achieve its nonprofit publishing mission, PMN partners with more than 80 organizations, which include universities, nonprofits like NCGA, and agribusinesses.
