| Abstract/Contents: | "Annual bluegrass is commonly found on golf courses today. Many turfgrass managers choose to maintain annual bluegrass while others try to eliminate it. Annual bluegrass can produce many seedheads in the spring, regardless of mowing height. Seedhead production can create an undesirable sward for a variety of reasons. First, seedheads can be aesthetically displeasing resulting from an off white color during the peak production period. This production of annual bluegrass seedheads may result in a decrease of plant health. Additional stress, such as traffic or lack of moisture, may lead to an undesirable sward. Second, annual bluegrass seedheads may adversely affect turfgrass playability, especially in regards to a golf course putting green. Ball roll and smoothness are often compromised by annual bluegrass seedheads. Chemical applications of plant growth regulators and other materials have been used for the suppression of annual bluegrass seedheads. The correct timing of the application of these materials are imperative. If applications are made too early and temperatures are not optimal for growing conditions, plant health may be an issue. If materials are applied too late in the season, seedhead suppression may not be accomplished. Material application timings can differ. A common material application timing is when the annual bluegrass is in the boot stage of development. The boot stage should be monitored by sampling annual bluegrass plants in different areas of the overall sward. Many studies have been conducted to evaluate various plant growth regulators for the suppression of annual bluegrass seedheads. For example, Embark T&O is a growth regulator which provides excellent suppression when applied at the correct rate and timing. Other options include a tank mix of Primo Maxx and Proxy. This tank mix has shown good suppression in several studies. Researchers continue to evaluate new products, product combinations, and application timings to better suppress annual bluegrass seedheads." |
