Pioneer HiBred has introduced two new products into the U.S. corn market, Optimum AcreMax RW (OAM RW) and Optimum AcreMax 1 (OAM 1). Both products have been approved by the EPA and are commercially available as a new option to consider for the 2011 growing season. Pioneer is the first company to offer "in the bag" refuge for Bt corn. The OAM RW and OAM 1 blends each contain 90 percent Bt corn that targets corn rootworm and a 10 percent rootworm refuge. While a potentially convenient benefit, some growers may find that this complicates refuge planting. Let’s run through the basics.
