| Abstract/Contents: | "Annual bluegrass (Poa annua L.) is one of the most problematic winter annual weeds in various turfgrass systems across the country, drastically driving up management costs and greatly reducing the aesthetic value of turfgrass. A sound understanding of weed seedling emergence pattern allows for appropriate timing of management interventions, yet this knowledge is limited for annual bluegrass. To evaluate annual bluegrass seedling emergence patterns, experiments are being conducted in Texas in two different USDA climatic zones (8b and 9a) over multiple growing seasons, from the fall of 2019 through the spring of 2022. For this purpose, artificial annual bluegrass seedbanks were established in eight quadrats (1 m2 ) in each site in a turf field area cleared of all vegetation. Seedling emergence was evaluated on a biweekly basis throughout the year by counting and removing emerged seedlings till seedlings cease to emerge from the soil seedbank. Additionally, soil temperature and moisture were measured (5 cm depth) using weather sensors installed at the site. Between fall 2019 and spring 2020, one distinct emergence peak was observed at the zone 8b site, with 95% emergence observed within 9 weeks of first seedling emergence. Conversely, the zone 9a site had two distinct emergence peaks, with 95% emergence occurring at 19 weeks after the first seedling emergence. The preliminary results of this study indicate that environmental conditions can tremendously influence annual bluegrass seedling emergence patterns; management programs will greatly benefit from timely interventions implemented based on seedling emergence prediction." |
