Yield Performance and Herbicide Tolerance of Enlist™ Corn Hybrids.

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 Enlist^TM 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 Enlist^TM 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 Enlist^TM hybrids to withstand at least 2X the anticipated rate of herbicide that will be used for weed control.  Results of these studies indicate that Enlist^TM hybrids have agronomic characteristics that are equal or superior to null isolines and provide complete protection to 2X applications of 2,4-D.
