- The industry trend to faster golf putting greens has led to recent development of high density creeping bentgrass (Agrostis palustris Huds.) cultivars that tolerate very close mowing. These cultivars also claim a finer leaf texture and improved competitiveness with the invasive weed, annual bluegrass (Poa annua L.). In this multi-year on-site field study, newer cultivars showed superior quality, color, leaf texture, density and resistance to Poa invasion than older cultivars. However, there were no significant differences among cultivars in ball roll speed (Stimpmeter readings) or thatch/mat depth.
