| Abstract/Contents: | Presents a study with the following objectives: "1. Assess the population dynamics of turf mixtures comprised of annual bluegrass and individual cultivars of creeping and velvet bentgrass grown on soil- and sand-based rootzones. 2. Evaluate the influence of traffic stresses on the population dynamics of individual bentgrass cultivars mixed with annual bluegrass. 3. Identify the time of year when it is most effective to establish bentgrass cultivars with minimal annual bluegrass invasion. 4. Assess the effect of environmental conditions at the time of germination on the expression of annual or perennial biotypes in a sward containing annual bluegrass turf." Reports that "the least invasion of annual bluegrass during establishment occurred for June and August seeding dates," and that "plots renovated with Penncross had consistently lower bentgrass population than other cultivars." Also states that "high-density creeping bentgrass cultivars have shown excellent resistant [resistance] to annual bluegrass encroachment under a range of traffic conditions," and that "velvet bentgrass had considerably better tolerance of traffic stresses than previously reported." This three-year study began in 1998. |

| USGA Summary Points: | The least invasion of annual bluegrass during establishment occurred for June and August seedling dates compared to the May, September, and October seeding dates. Plots renovated with Penncross had consistently lower bentgrass populations than A-4 and L-93. SR-7200 velvet bentgrass had similar populations to A-4 and L-93 in June and August seeding; however, the cultivar had lower population for September and October seeding. High-density creeping bentgrasses cultivars have shown excellent resistant to annual bluegrass encroachment under a range of traffic conditions. Velvet bentgrass had considerably better tolerance of traffic stresses than previously reported. |
