Benjamin P. Sperry; Stephen F. Enloe; Candice M. Prince; et al. Invasive Plant Science and Management 2023. doi:10.1017/inp.2023.14

Other claims from this paper (8)

Intervention effect Doubling the maximum labeled sethoxydim rate did not always improve efficacy.
Intervention effect In the small-plant run, P. repens control and biomass reduction were similar across carrier volumes.
Intervention effect For mature P. repens, lowering carrier volume increased efficacy.
Intervention effect S. bakeri injury rose with sethoxydim rate and reached 45% by 42 DAT.
Intervention effect S. bakeri injury did not differ among carrier volumes at 14 and 28 DAT.
Intervention effect S. bakeri aboveground biomass reduction was driven mainly by sethoxydim rate and reached 40% to 50%.
Intervention effect S. bakeri belowground biomass was 20% to 32% greater at lower carrier volumes.
