Two varieties of bahiagrass were evaluated under Florida conditions for forage tolerance to the new herbicide, aminocyclopyrachlor (ACP), which is essential for product development decisions. Herbicide treatments included ACP alone at 70 and 140 g ai ha(-1), ACP + chlorsulfuron at 69+27 and 138+ 54 g ai ha(-1), ACP+2,4-D amine at 70+532 g ai ha(-1) and 140+1,064 g ai ha(-1), ACP+triclopyr-amine at 70+140 g ai ha(-1) and 140+280 g ai ha(-1), and ACP+ metsulfuron at 46+7, 78+12, and 168 + 26 g ai ha(-1), and also included a nontreated check. 'Argentine' bahiagrass was the most tolerant forage species, and 'Pensacola' bahiagrass was sensitive to ACP + metsulfuron and initially to ACP + chlorsulfuron. Herbicide applications using ACP, when labeled, will likely provide good to excellent control of several weed species, with little long-term impact on bahiagrass forage production when the cultivar is known.
