Abstract/Contents:"The premix herbicide, Speedzone (carfentrazone + 2,4-D + mecoprop + dicamba) at 4.0 pt product/A provided rapid postemergence (POST) control of khakiweed also known as mat chaff-flower (Alternanthera caracasana) and gave 82% control at 17 days after treatment in one of three experiments. Spotlight (fluroxypyr) at 1.0 pt product/A alone was only effective at about 50%. BAS-514 and BAS-790 were not effective against khakiweed when applied alone. In a second experiment, sequential applications of Speedzone and Spotlight plus Turflon Ester (triclopyr) provided exceptional control of greater than 95%. Initial applications of the POST application that were combined with Gallery (isoxaben) offered control of new emerging seedlings of khakiweed. Monument (trifloxysulfuron) combined with Gallery gave decreased khakiweed control compared to Monument applied alone. An antagonistic effect could be occurring with the tank-mix combination of the two herbicides. Carfentrazone containing products, QuickSilver at 2 oz produce/A alone was not effective against khakiweed compared to the premix product Speedzone. For the ALS-inhibiting herbicides, flazasulfuron and Certainty (sulfosulfuron) were the least effective while penoxsulam and Image (imazaquin) were comparable to Monument in providing about 50% control."
