Abstract A limited number of herbicides and sites action are registered for use in sugarcane Louisiana. Repeated the same can lead to evolution herbicide resistance weeds. Therefore, it is critical evaluate additional provide growers with options rotating reduce risk resistance. Topramezone, indaziflam, a formulation including mesotrione, bicyclopyrone, atrazine, S -metolachlor, along more common applications (pendimethalin, metribuzin, clomazone, diuron), were evaluated spring injury sugarcane, weed control, yield, sugar yield. Of these treatments, clomazone applied diuron was only combination consistently injure crop, estimates ranging from 11 36%, which frequently resulted reduced yield losses between 2.3% 24.1% non-treated control. In most an increase itchgrass counts observed harvests, indicating that control strategies will be needed fields infested this weed. However, topramezone alone triclopyr well tolerated by injuries 0 11% two weeks after treatment. Indaziflam combined application -metolachlor at or under 10% The tolerance suggests they incorporated into management sugarcane. These would available help mitigate herbicide-resistant
