چکیده
Abstract Greenhouse experiments were conducted in 2020 to investigate the effects of carrier volume and sethoxydim rate on torpedograss ( Panicum repens L.) control sand cordgrass Spartina bakeri Merr.) response from a single application. biomass reduction generally increased with increasing rates evaluations at 14, 28, 42 d after treatment (DAT); however, 2X maximum labeled did not always result efficacy. In first experimental run, which consisted small plants, P. reductions largely similar among tested volumes (37, 187, 935 L ha −1 ). However, run 2, larger, mature efficacy when was reduced. injury rate, reaching 45% by DAT. no differences S. observed 14 28 DAT evaluations. aboveground also driven increases rather than reduced volumes, 40% 50% initial biomass. belowground 20% 32% greater treatments applied 37 or 187 compared those . Overall, these data suggest that selective may be enhanced through reducing native, perennial, caespitose grasses exhibit tolerance rhizomatous Future research should further test hypotheses under field conditions operational scales.
