Another Corn Company Gets In-Bag Refuge Go Ahead

April 13, 2011 11:07 AM

Add Dow AgroSciences Refuge Advanced powered by SmartStax to the lineup of in-the-bag options for 2012. The company has received registration from the U.S. Environmental Protection Agency and is good to go next year from the federal regulatory standpoint. Commercialization is pending individual state authorizations and notifications. Dow expects full commercial launch for 2012 planting.

Refuge Advanced is a blend of 95% SmartStax and 5% refuge (non-Bt) seed. Those who plant Refuge Advanced will no longer need a separate, structure refuge for above-or below-ground pests in the Corn Belt. In cotton growing regions, a separate 20% structured refuge is still required.
Casey Onstot, traits marketing manager for Dow AgroSciences says growers will appreciate the convenience and simple solution to refuge compliance. “The premium seed blend saves time by allowing growers in the Corn Belt to plant a single product across the entire field. They won’t have to change out refuge seed in planter boxes, handle insecticide boxes, or plant any separate structured refuge for above- or below-ground insects on those acres planted with Refuge Advanced.”
SmartStax is a collaboration between Monsanto and Dow AgroSciences. It is a combination of each company’s corn traits that provide multiple modes of action and two herbicide tolerance traits. Monsanto has also received
One challenge to an integrated refuge is blending the seed properly in the bag to ensure even distribution across the field. Information provided by Dow AgroSciences indicates the weight and size of refuge seed will matched to the SmartStax seed to help maintain an even blend.
Onstot says a proprietary seed blending process is being used to avoid “hot spots” due to large clusters of refuge plants in one area. SmartStax hybrids will also be blended with an agronomically equivalent refuge hybrid, so refuge plants will look similar to the traited plants for a uniform stand.
Refuge Advanced will be offered only through Dow AgroSciences seed brands, including Mycogen Seeds, Brodbeck Seeds, Dairyland Seed, Pfister Seeds, Renze Seeds and Triumph Seeds. Learn more at
