Abstract

Three field experiments were conducted to evaluate efficacy of BAS 625, cyhalofop, and fenoxaprop plus isoxadifen when applied alone or with acifluorfen plus bentazon, acifluorfen, bentazon, triclopyr, bensulfuron, halosulfuron, carfentrazone, and propanil. Broadleaf signalgrass control with fenoxaprop plus isoxadifen was reduced by triclopyr and halosufuron. None of these herbicides reduced Amazon sprangletop control by fenoxaprop plus isoxadifen. Barnyardgrass control with fenoxaprop plus isoxadifen was reduced by halosulfuron and propanil. Barnyardgrass and Amazon sprangletop control by cyhalofop was reduced by bentazon plus acifluorfen, bentazon, acifluorfen, triclopyr, bensulfuron, or halosulfuron. Broadleaf signalgrass control with cyhalofop was reduced by triclopyr and halosulfuron. Amazon sprangletop control by cyhalofop was reduced by all herbicides. Barnyardgrass control with BAS 625 was reduced when applied with propanil, bentazon, or bentazon plus acifluorfen. Broadleaf signalgrass control with BAS 625 was reduced when applied with bentazon plus acifluorfen. Amazon sprangletop control with BAS 625 was reduced when applied with bentazon, acifluorfen, halosulfuron, or propanil.
