A study was conducted at three locations in Louisiana to evaluate the interactions of imazamox at 44 g ai ha(1) mixed with propanil, thiobencarb, or with a prepackaged mixture of propanil plus thiobencarb. A synergistic response was observed for red rice control for all treatments at 14 days after treatments (DAT); however, at 21 DAT a neutral response was observed for imazamox mixed with propanil or thiobencarb. A synergistic response occurred for red rice control when imazamox was mixed with propanil plus thiobencarb at 3360 g ai ha(-1) for all evaluation dates; however, imazamox mixed with propanil plus thiobencarb at 1680 g ha(-1) resulted in synergism at the same evaluations except at 35 DAT with neutral response. Synergism was observed for barnyardgrass control with imazamox mixed with propanil plus thiobencarb at 3360 g ha(-1) at 35 and 49 DAT. The only antagonism observed for barnyardgrass control was at 42 DAT with imazamox plus propanil at 840 and 1680 g ha(-1) or mixed with the prepackage mixture at 1680 g ha(-1). Rice treated with imazamox mixed with propanil plus thiobencarb at 3360 g ha(-1) yielded 5770 kg ha(-1).
