Abstract/Contents: | "Decreased stand uniformity together with reduced aesthetics and playability caused by annual bluegrass (Poa annua L.) intrusion in creeping bentgrass (Agrostis stolonifera L.) putting greens is one of the major problems that superintendents face with managing newer playing surfaces. Few herbicides are registered for selective control of annual bluegrass in bentgrass greens, thus use of plant growth regulators (PGRs) remains the primary method of annual bluegrass suppression. This study was conducted to evaluate eight PGR treatments, employed as a series of 15 consecutive, biweekly applications to suppress annual bluegrass encroachment in creeping bentgrass 'Pure Distinction' maintained as a golf course putting green in Los Angeles, CA. Results showed that best annual bluegrass suppression was seen with products containing paclobutrazol at 0.59 L/ha or flurprimidol, trinexapac-ethyl and paclobutrazol mix at 1.10 L/ha. Nevertheless, both treatments caused some injury, which increased over time. Additionally, these treatments caused significant turf darkening, which may be desirable on putting greens. This research confirms the potential of PGR use to limit annual bluegrass infestation on creeping bentgrass greens in a Mediterranean climate and reveals the most effective treatments that could be utilized in a regular maintenance program." |
