Abstract/Contents:"We are researching traffic applications to Kentucky bluegrass (Poa pratensis L.) cultivars and experimental selections to improve the playing surface quality of recreational sites. We observed several unexpected Kentucky bluegrass responses to traffic during 2020 and 2021; the objective of this Abstract is to report on dollar spot disease (caused by Clarireedia jacksonii) and spring green-up responses of Kentucky bluegrass subjected to traffic. The 2017 NTEP Kentucky bluegrass test (three replications of 89 entries) was seeded in September 2017 on a loam in North Brunswick, NJ. Traffic was applied in a strip across Ā½ of each plot using a combination of the Rutgers Wear Simulator and the Cady Traffic Simulator during autumn 2018, summer and autumn 2019, and summer and autumn 2020; the other approximate Ā½ of each plot did not receive traffic (no traffic). Dollar spot and spring green-up were visually evaluated using a 1 to 9 scale where 9 equaled the least dollar spot and best spring green-up, respectively. Data were analyzed as a 2 (no traffic and traffic) x 89 (entries) factorial strip-plot design. Greater dollar spot incidence was observed in no traffic plots compared to traffic plots on 25 June and 20 July 2020. A significant traffic x entry interaction was detected on 25 June 2020; entries that exhibited the most severe dollar spot incidence in no traffic plots were DLFPS-340/3549, DLFPS-340/3548 Blue Knight, RAD 553, and A11-38. Trafficked Kentucky bluegrass plots exhibited better spring green-up compared to no traffic plots on 9 April 2021; a significant traffic x entry interaction was detected on this rating date. Fifty-one entries had better spring green-up under the level of traffic compared to no traffic. Entries with the best spring green-up under both levels of traffic were Barvette HGT, Barserati, A11-40 and A99-2897."
