Postemergence grass weed control options are limited in sweet corn. Accent is labeled to control annual grasses in approved processing sweet corn hybrids. The list of Accent-approved hybrids has been continually updated by DuPont (Table 1). Accent is not recommended for use on other hybrids because the risk of crop injury may not be known. Accent has only been labeled for use on processing sweet corn. However, an Accent label for fresh market sweet corn is expected in 2006. It will be important to know which fresh market hybrids have good tolerance to Accent. A multi-state study was conducted in 2005 to test the tolerance of 114 hybrids, which provides a preliminary indication of Accent tolerance (Table 2).
