Abstract/Contents:Discusses Poa trivialis, rough bluegrass, stating that "although used extensively for overseeding warm-season turf in the South [it] is a troublesome weed in golf courses from the Midwest to the mid-Atlantic states." Presents a study conducted "to determine the most effective selective herbicide strategies for controling P. trivialis." Details the materials and methods used in the study, stating that "treatments included two initial application dates (mid- to late May and mid- to late June), two herbicides (Certainty and Velocity) and two application rates of each herbicide." Results indicate that "when averaged over all application dates and rates, Velocity outperformed Certainty in the initial studies in both Indiana and Illinois." Also discusses follow-up studies, stating that "four Certainty 75WDG treatments, three Velocity 80SP treatments and an untreated check were included at each location." Reports that "there was tremendous variation in the performance of Certainty and Velocity." Offers potential Poa trivialis control methods, suggesting "three applications of Certainty at 0.50 ounce/acre (35.0 grams/hectare) at two-week intervals or four applications of Velocity at 0.98 or 1.3 ounces/acre (68.7 or 91.1 grams/hectare) at two-week intervals."
