The registration was requested by the Tennessee Biofuels Initiative, the Tennessee Department of Agriculture and DuPont Crop Protection. It was granted based on the lack of available herbicides for effectively controlling grasses and the performance of Accent, which has been evaluated for efficacy against grass weeds in Tennessee for the past three years.

University of Tennessee trials show increased yields of 49 to 76 percent on varieties of switchgrass with the use of Accent, which was originally registered for use in controlling tall grasses in corn.
