The Agricultural Biotechnology Stewardship Technical Committee (ABSTC) reported that corn Insect Resistance Management (IRM) compliance has remained stable through the period 2007 through 2009. 
"Our industry is committed to ensuring that growers understand the importance of Bt technology stewardship so that they continue in the future to provide benefits to growers and the environment," said Nick Storer, Ph.D., ABSTC Steering Committee chairman. "While the overwhelming majority of growers are in full or partial compliance with IRM requirements, it is crucial that we all continue working together to sustain these important technologies." 
The ABSTC submitted the results to the Environmental Protection Agency (EPA) as part of the 2009 Bt corn IRM Compliance Assurance Program (CAP) Report, which includes an annual report of the compliance results and a summary of actions being taken by Bt registrants to promote and support IRM compliance for the upcoming growing season.
