Dow AgroSciences has developed a trait (aad1) that increases selectivity of the phenoxyacetate and aryloxphenoxypropionate (fop) herbicides in maize (Zea mays L.) via metabolic detoxification. Maize enabled with this gene will be a key part of the EnlistTM Weed Control System.  This gene has been introgressed into several maize inbreds that have in turn been used to produce a range of hybrids.  Field trials were conducted across multiple locations to evaluate agronomic performance of EnlistTM hybrids compared to isogenic checks.  In addition, select trials were treated with 2,4-D at rates up to 2240 g ae/ha to evaluate the ability of EnlistTM hybrids to withstand at least 2X the anticipated rate of herbicide that will be used for weed control.  Results of these studies indicate that EnlistTM hybrids have agronomic characteristics that are equal or superior to null isolines and provide complete protection to 2X applications of 2,4-D.
