Abstract/Contents:"Bulbous Bluegrass (Poa bulbosa L.) is a widespread, yet relatively unstudied, invasive cool-season grass that reproduces primarily via bulblets. Few herbicides are labeled for its management in rangelands, and limited research exists that evaluates best control methods. Our objective was to evaluate the efficacy of various herbicides in controlling bulbous bluegrass. We established two field studies in northeast Wyoming in May 2017 to evaluate 11 herbicides alone, and combined with glyphosate, for their impacts on bulbous bluegrass. We applied herbicide treatments to 3 x 9 meter plots as a split-plot randomized completely block design with four blocks at each site. Glyphosate (520 g ae·ha-1) was applied to 1/3 of each block following other herbicide applications. We collected post treatment data 30 and 160 day after treatment (DAT). We recorded canopy cover by species in ¼ m2 quadrats at a density of 6 quadrats per 0.3 are. Additionally, we visually estimated the control (%) of bulbous bluegrass and the damage (%) to perennial grasses and forbs. Glyphosate reduced bulbous bluegrass canopy cover 30 DAT at both sites (p<0.05), but we did not observe a glyphosate by other herbicide interaction. Litter (dead plant matter) displayed main effects of herbicide and glyphosate 30 DAT. By 160 DAT (October), most herbicides had higher litter than the nontreated check (p<0.05) but we observed no meaningful differences in bulbous bluegrass cover among treatments. Data to be collected in spring 2019, after bulbous bluegrass is more actively growing, will reveal more substantial impacts of herbicide treatments."
