As the 2011 planting season approaches, the National Corn Growers Association (NCGA) reminds Bt corn growers that the development of an IRM plan for their farm is an essential and required part of their planning process.  In addition to information provided by seed dealers and the Bt trait providers, the NCGA has established a number of resources for growers developing IRM plans and a refuge strategy for their farm. 

NCGA recently launched a new IRM calculator to help clarify refuge system options and show growers how to execute the requirements properly.  The IRM calculator was developed in collaboration with ABSTC companies to ensure that it reflected all Bt products available in the industry today.  The IRM calculator is available at

“In addition to protecting current technology, adherence to refuge requirements is important for the commercialization of next generation biotech traits,” said Blindauer. “Future traits that build on today’s technology will only be successful if today’s technology remains effective.”
