| Abstract/Contents: | "Preemergence (PRE) herbicides have been reported to injure both foliage and roots of hybrid bermudagrass [C. dactylon (L.) Pers. x C. transvaalensis Burtt-Davy] established in sand. Research was conducted to evaluate the influence of organic matter content on hybrid bermudagrass injury following PRE herbicide applications to plants established in sand culture. Washed sod was established in mini-rhizotrons constructed with sand rootzones varying in organic matter (e.g., sphagnum peat mass) content (0.000, 0.003, 0.007, and 0.012 kg kg-1). Herbicide treatments included indaziflam (35 and 52.5 g ha-1) and prodiamine (840 g ha-1). Bermudagrass injury was visually evaluated weekly after application using a 0 (no injury) to 100 (complete kill) scale. At 6 weeks after treatment (WAT) roots were washed free of debris and excised as close to the crown as possible. WinRhizo software was used to characterize root length (cm), root length density (cm cm-3) (RLD), and root surface area (cm2). Significant foliar injury was only observed with indaziflam at 52.5 g ha-1. When applied to sand with 0.000 kg kg-1 organic matter injury measured 61% by 6 WAT. Comparatively, injury with indaziflam at 52.5 g ha-1 was reduced by 40% with plants established in sand with 0.007 kg kg-1 organic matter. Root length, RLD, and root surface area were greatest in sand rootzones with ? 0.007 kg kg-1 organic matter regardless of herbicide treatment; however, only indaziflam at 52.5 g ha-1 and prodiamine reduced root parameters relative to the untreated check. Data in the current study illustrate that organic matter content can affect above- and belowground injury following PRE herbicide applications to sand rootzones." |
