| Abstract/Contents: | "Aminocyclopyrachlor is a new herbicide under development by DuPont as either the methyl-ester (DPX-KJM44) or as the free acid (DPX-MAT28). KJM44 is being evaluated both as a wettable powder (WP) and as a granular (GR) material and MAT28 as a liquid (SL) formulation. Studies were conducted with aminocyclopyrachlor at the University of Florida West Florida Research and Education Center to determine warm-season turfgrass tolerance and postemergence weed management at rates of 30 to 320 ga a.i./ha. KJM44 (both WP and GR) and MAT28 at 50 to 80g a.i./ha provided excellent ( 95%) pennywort (dollarweed) (Hydrocotyle spp.) control. The KJM44 WP formulation provide more rapid control (95% by 4 wk after treatment (WAT) than the GR formulation (95% by 6 WAT) but both eventually controlled the pennywort. Pennywort control remained excellent for at least 14 WAT. Virginia buttonweed (Diodia viginiana) control required a higher rate of aminocyclopyrachlor (80 to 100 g/ha) and control ranged from 85 to 90% 3 to 4WAT. Control declined over time and was only 50 to 70% by 6 to 7 WAT. Aminocyclopyrachlor also controlled Florida betony (Stachys floridana), chamberbitter (Phyllanthus niruri) and white clover (Trifolium repens) 85 to 100% when applied postemergence at 50 to 70 g/ha. Aminocyclopyrachlor did not control Florida pusley (Richardia scabra) or torpedograss (Panicum repens). When applied at 80 g/ha, St. Augustinegrass injury was less with the KJM44 GR (25%) than with the WP (75%) formulation 4 WAT. Zoysiagrass and bermudagrass were injured 20% or less 3WAT when aminocyclopyrachlor was applied at 80 g/ha. Centipedegrass was the most tolerant of the turfgrass species evaluated and exhibited less than 20% injury following aminocyclopyrachlor application at rates up to 220 g/ha." |
