New Turf Website

BeaverTurf.com - the new turfgrass website from Oregon State University - is nearing completion.  We hope you like the new site and the information and resources that it provides. 

Please let us know about any bugs, errors, or other problems that you might encounter, as well as any other feedback you may have.  Thanks and happy surfing!

Creeping Bentgrass

Creeping Bentgrass


For as long as golf has been played in the Pacific Northwest creeping bentgrass has been planted on putting greens, first as a component of South German mixed bentgrass, and later as seeded or stolonized varieties. In recent years, intense breeding and selection work has resulted in a flood of new cultivars with widely varying characteristics and generally much improved surface quality. While early creeping bentgrasses quickly gave way to annual bluegrass, newer cultivars are much more competitive and may prove to be much more persistent.

2008 Evaluation of Turf Phytotoxicity and Quality of a “Providence” Creeping Bentgrass Putting Green Resulting from Multiple Applications of Proxy, Primo, & Trimmit Growth Regulators

Preliminary Report


The primary objective of this trial is to determine whether repeated applications (2, 3, or 4) of Proxy (ethephon) or Proxy + Primo (trinexpac-ethyl) causes phytotoxicity to Providence creeping bentgrass maintained at putting green height. A secondary objective is to evaluate turf quality of putting green turf treated with Proxy, Proxy + Primo, or Trimmit (paclobutrazol) growth regulators. The Trimmit was applied at two rates alone and with additional fertilizer.

2007 Evaluation of Sensitivities of Annual Bedding Plants to Mesotrione (Tenacity) Herbicide

Final Report


The purpose of this trial was to evaluate the sensitivity of four species of annual bedding plants to Mesotrione (Tenacity) herbicide. The initial treatments were applied 24 hours before planting. A second application was made six weeks later over the top of the plants.
