| Abstract/Contents: | "The auxin-mimicking herbicide quinclorac controls crabgrass (Digitaria spp.) after emergence in cool- and warm-season turfgrass species. Quinclorac resistance has been confirmed in smooth [Digitaria ischaemum (Schreb.) Muhl.] and large crabgrass [Digitaria sanguinalis (L.) Scop.]. Two Mississippi smooth crabgrass populations have been confirmed as quinclorac-resistant. Field experiments were conducted to evaluate programmatic approaches to control one of these populations. Treatments included the sequential application of pre-emergence herbicides on 17 Feb. and 10 Apr. 2020, and 25 Feb. and 6 Apr. 2021, alone or with 0.84 kg quinclorac ha-1 applied postemergence on 10 April 2020 and 6 April 2021, then a second application of quinclorac alone on 18 June 2020 and 16 June 2021. Pre-emergence treatments included 0.05 kg indaziflam ha-1, 0.84 kg prodiamine ha-1, 0.56 kg dithiopyr ha-1, and 0.47 kg prodiamine ha-1 + 0.21 kg imazaquin ha-1 + 0.73 kg simazine ha-1. Commercial standards applied on 10 Apr. and 18 June 2020, and 6 Apr. and 16 June 2021 included 0.16 kg pinoxaden ha-1 and 2.27 kg monosodium methanearsonate ha-1. Four weeks after the last application, all treatments except quinclorac (2020 and 2021), dithiopyr (2020), and pinoxaden (2020) controlled quinclorac-resistant smooth crabgrass by >90%. Various standard pre-emergence herbicides adequately controlled the resistant population. Quinclorac combined with pre-emergence strategies provided greater control of smooth crabgrass than quinclorac alone. Ongoing research is investigating the mechanism of quinclorac resistance. Future research should screen a wider distribution of populations and investigate cross- and multiple resistance." |
