Abstract/Contents:"Downy brome is a highly invasive annual grass native to the Mediterranean that has spread throughout much of the United States. Indaziflam is a relatively new preemergence herbicide that has a long period of soil residual activity and has been shown to prevent germination of annual grasses for at least three years. This project was established to evaluate the efficacy of herbicides alone or in combination with indaziflam, and to determine perennial forb tolerance to various treatments. Other herbicides include propoxycarbazone, rimsulfuron, glyphosate, and imazapic. The study was established at a site near Richmond, Utah that has a variety of native and naturalized perennials and is moderately infested with downy brome. Treatments were applied November 2016 to plots measuring 6 by 18 m arranged in a randomized complete block design, replicated 4 times. Species cover was evaluated using point-line-intercept transects, recording a point every 15 cm. All treatments reduced downy brome cover. Propoxycarbazone, imazapic, and rimsulfuron reduced cover by 35, 81, and 95%, respectively. The addition of indaziflam with other herbicides increased downy brome control for all treatments except glyphosate. Glyphosate alone and all combinations including indaziflam exhibited the highest downy brome control, with cover reductions ranging from 98.5 to 100%. Rimsulfuron, imazapic, and glyphosate treatments alone increased cover of prickly lettuce. Cover of Hooker's balsamroot, a native perennial, was not altered by any treatment whereas cover of Western wheatgrass was significantly reduced in plots treated with glyphosate alone, glyphosate with indaziflam, and imazapic with indaziflam. This project provides understanding on how herbicide treatments and combinations affect plant community dynamics."
