Sweet corn weed management can be challenging because of the limited number of postemergence herbicides, the potential for these herbicides to cause injury, and the weed spectrum to be controlled. Currently, Callisto and Impact are labeled for use in sweet corn while Laudis is nearing registration and Status is being evaluated for postemergence use in sweet corn. Sweet corn hybrids have had limited evaluation to determine tolerance to Impact and Laudis. We are not aware of any public testing to determine the tolerance of sweet corn hybrids to Status. Therefore, three field studies and one greenhouse study were conducted to evaluate hybrid tolerance to Status, Impact and Laudis applied postemergence.
