In the last decade, the evolution of herbicide-resistant weeds, especially barnyardgrass (Echinochloa crus-galli (L.) Beauv.), to acetolactate synthetase (ALS) inhibitor herbicides, has accelerated. This research focused on the analysis of the new cultivars ACCase herbicide tolerance. Complete randomized blocks designed were used in two regions, using two new cultivars and early seeding dates.
