Kentucky bluegrass (Poa pratensis L.) golf course fairway infested with annual bluegrass (Poa annua L.) can be unattractive, hard to manage, and have reduced playability during much of the golf season. The objective of this study was to determine the efficacy of Tenacity 4SC combined with several herbicides to eliminate Poa annua from Kentucky bluegrass fairways.
Materials and Methods
Research was conducted on a Kentucky bluegrass fairway infested with P. annua at the Palouse Ridge Golf Club at Washington State University in Pullman, WA. Treatments were: Tenacity 5 fl oz/A + Xonerate 2 oz/A, Tenacity 4 fl oz/A + Xonerate 1 oz/A, Tenacity 5 fl oz/A + Turflon 16 fl oz/A, 19660A 1 fl oz/A + Turflon 16 fl oz/A, Tenacity 5 fl oz/A + Trimmit 16 fl oz/A, and Tenacity 5 fl oz/A + Trimmit 16 fl oz/A + Turflon 16 fl oz/A. Initial treatments were applied May 2, 2013, and repeat treatments were made on May 23, and June 13, 2013. Applications in 2014 are currently being evaluated in a spring/spring program (only 2013 data presented).
Tenacity 5 fl oz/A + Xonerate 2 oz/A and Tenacity 4 fl oz/A + Xonerate 1 oz/A resulted in the greatest reduction of P. annua, 86 and 82%, respectively, compared to the controls (Fig. 1). However, associated with the Tenacity 5 fl oz/A + Xonerate 2 oz/A treatment was a high level of P. annua phytotoxicity and at times an unacceptable phytotoxicity on Kentucky bluegrass (Fig. 2). In addition, open, depressed areas in the fairway where the P. annua had died presented undesirable playing conditions during peak summer play. It was not till the early fall that the Kentucky bluegrass aggressively began to fill these depressions and a noticeable shift in the fairway population toward Kentucky bluegrass was evident (Fig. 3 and 4). Tenacity 4 fl oz/A + Xonerate 1 oz/A also resulted in a high level of P. annua phytotoxicity for several weeks, but at a lower level of Kentucky bluegrass phytotoxicity and did not cause P. annua to quickly disappear creating open areas and depressions in the fairway.
Tenacity 4 fl oz/A + Xonerate 1 oz/A may be the most desirable P. annua control option to consider in terms of seasonal playability. Complete P. annua control was not achieved with any treatment; therefore, a multi-year program may be needed to achieve this goal.
Dear Members of the Oregon GCSA,
I am asking for your help today in an important initiative that will benefit not only you and your facility, but also the golf course management industry as a whole.
The Golf Course Superintendents Association of America is currently collecting important data from superintendents nationwide regarding water use and conservation in the game through the Golf Course Environmental Profile (GCEP) Water Use and Conservation Practices survey. Funded by The Environmental Institute for Golf through generous sponsorship by the USGA, this particular survey is the initial step in the second phase of the GCEP, an effort to help measure our industry’s efforts over time, which will enable golf to better demonstrate its environmental stewardship and ensure the future of the game. We are asking members and non-members alike to take 15 minutes to participate in this survey, which can be completed by visiting gcsaa.org.
Why is your participation in the GCEP and especially the water use and conservation practices survey so vital? Having current data on these important areas of golf course management give our industry the best tools by which to respond to government inquiries and proposed regulations, support research/innovation and provide education and resources for those who professionally manage the golf facility. The data also helps creates a historical record of the positive changes in the way golf courses are managed, which can then be used to demonstrate the game’s environmental stewardship.
Below are a few specific ways the data from the first round of surveys have been used:
- University turfgrass scientists use this data in their research and within the classroom to illustrate the scope of the golf industry. There is no other resource that has been peer reviewed and represents the golf course industry across the U.S.
- The We Are Golf coalition utilizes this data on its website and during its visits to Capitol Hill during National Golf Day. This is the primary source of data that reflects golf’s environmental stewardship efforts and properly positions our use of resources.
- In the face of potential regulatory actions pertaining to water use and the use of other inputs, the golf industry needs current data regarding our operations and environmental practices. These surveys deliver that important data.
- The industry frequently provides information from these surveys to the media, conservation organizations, the public and other special interest groups to portray the golf course industry’s professionalism and hard work.
Most importantly, though, the data gathered in these GCEP surveys supports GCSAA members and the job we do every day. This is why your association has undertaken these surveys on your behalf. Your participation in these surveys is critical.
In addition to taking this survey yourself, please help us further by encouraging superintendents in your area—both GCSAA members and non-members alike—to take part as well. This is one of the most important activities that the GCSAA undertakes on behalf of the golf course industry, and the participation of as many superintendents as possible is vital.
Again, to take the GCEP Water Use and Conservation Practices survey or to learn more about the GCEP in general, visit www.gcsaa.org. Thank you.

Emergency (Temporary Rule Prohibiting the Use of Dinotefuran and Imidacloprid on Linden Trees
On June 26, 2014 the Oregon Dpartment of Agriculture (ODA) enacted an emergency (temporary) rule prohibiting the use of any product containing the neonicotinoid insecticides dinotefuran or imidacloprid, regardless of application method, on linden trees. The Temporary Administrative Rule will be in effect June 26 - December 23, 2014, OAR 603-057-0387. Additional regulatory action may take place before or after the expiration date of the temporary rule.
What Does this Mean to You?
This means that if you have a container label that provides directions for use on linden trees, you can not apply it to linden trees, basswood trees or other Tilia species.
This rule prohibits the use of dinotefuran or imidacloprid to Tilia spp., regardless of application method, including but not lmited to: foliar, bark treatment, soil drench, tree or soil injections, bark injection and basal bark application.
Why is the Department Taking this Action?
In 2014, there were numerous bee kills associated with the use of these products on linden trees. In response, ODA required as a condition of 2014 state pesticide registration that a label statement prohibiting use on linden trees would be required for products containing dinotefuran or imidacloprid. The Department embarked on substantial educational and outreach efforts regarding the hazards of using these active ingredients on linden trees and the new restrictions on pesticide labels.
In 2014, pesticide users continued to use products with old labels on linden trees, and as a result more bees died. In one incident, imidacloprid was foliarly applied to linden trees in bloom in June; and in another imidacloprid was injected into linden trees (pre-bloom) in March and May.
What happens if you apply dinotefuran or imidacloprid products to linden trees?
Failure to comply with this Administrative Rule may result in a number of enforcement actions, including, but not limited to: license suspension or revocations, or imposition of a civil penalty.
Information regarding the rule and trade names of pesticide products impacted by this rule may be found at oregon.gov/oda/pest/pages/pollinator.aspx
For additional information or questions, contact the Oregon Department of Agriculture at 503.986.4635, or email firstname.lastname@example.org.
I’d like to start my first President’s message by thanking all of the members of the OGCSA that elected me and are allowing me to serve as their President. I’ve been very fortunate to serve on the board with some very talented and amazing folks. I’d also like to thank Nolan Wenker for the many, many hours spent working on association business during his time as a board member and ultimately, as our President. To our peers who are rotating off the board, Brant Hathorn, Jason Leonard, and Randy Rider, thank you for taking the time to give back to the association. And finally, I’d be remiss to leave Linda Whitworth out of my many thanks, as she is the constant force among our Board of Directors and one of the main reasons we have such a strong organization. Over the next year, I will work tirelessly to carry out association business to the best of my ability and with all of our member’s best interests in the forefront in my mind.
With that said, next week will be busy with an Oregon Turfgrass Foundation meeting as well as an Oregon Golf Alliance meeting. It will be my first opportunity to work with the Oregon Golf Alliance and I’ve only met with the OTF once prior. I’m excited to meet some new people that love the golf business as much as I do. I hope that we can work together to advance and grow this game that is so important to us all!
Lastly, I’d like to remind everyone of the upcoming Rounds 4 Research auctions June 9-22 and August 1-10. We would love more courses to donate rounds for this important fundraising effort, which raised over $4,000 for our association in 2013. Thanks to all the courses that have already donated rounds and for those courses that haven’t had the opportunity to donate, it’s not too late. Please contact Linda Whitworth, David Phipps, or myself if you have any questions regarding the R4R. We would love to use the proceeds of these auctions to provide additional research funds in the PNW, above and beyond the Foundation pledge.
I look forward to the coming year and I am excited to do what I can to advance our association, our profession, and grow this game we all owe so much to! Please never hesitate to contact me with any questions or concerns you may have.

Dear OGCSA Members,
I am pleased to announce that OGCSA will again be participating in the Rounds 4 Research program. In 2012 the Environmental Institute for Golf (GCSAA’s philanthropic organization) launched the national Rounds 4 Research fund raising campaign having taken it over from the Carolinas GCSA who administered it on a smaller scale for three years.
In 2013, more than 50 GCSAA chapters and organizations participated in the auctions, which raised nearly $150,000.
Rounds 4 Research is based on the practice of securing donated rounds of golf and putting them up for public auction. The EIFG is working an online auction platform to sell the rounds and administer the various notification and revenue collection activities. At least 80 percent of the proceeds will be distributed to participating chapters or turfgrass organizations for use on research-based programs such as education, scholarships, advocacy and agronomic research.
It will take a committed effort from all of us to make this program a success. You will be asked to solicit rounds of golf from your facilities (and perhaps others) to be placed for auction. The more rounds we secure the greater the revenue we can generate in support of our members and chapters.
In the near future, we will be providing more information about the program and support documentation that you can share with others at your facility in soliciting rounds and attracting golfers to the auction site. From that perspective, it is important to remember that this program is for the benefit of all aspects of golf. This is not a program that will only benefit golf course superintendents.
Again, I am excited about the opportunity presented to us and the potential to invest in activities that will strengthen the profession and the game. In advance, I appreciate your support and will be communicating more about the program in the near future. Please contact me should you have questions.
OGCSA, Vice President
The annual GCSAA Chapter Delegates Meeting (Oct. 1-2) took on a decidedly different appearance this year, as the focus was not so much on the current state of affairs, but more on the future of the association and the profession.
“We were intent on getting feedback on what the profession would look like in the future, targeting the range of 2020 to 2025,” GCSAA President Patrick R. Finlen, CGCS, said. “It became obvious to the board through our discussions with those in the golf industry, including members, that the profession is experiencing rapid change. Superintendents are being asked to do more, and the tools and resources we use to do that job are changing. Just look at what is happening with technology. The game of golf may not be changing much, but how we manage it is.”

First Green is an innovative environmental education outreach program using golf courses as environmental learning labs. Last May, First Green held a demonstration field trip at Royal Oaks Country Club in the Portland area. After the field trip, representatives from area golf courses, the Pacific Northwest Golf Association, Oregon Golf Association, Washington State Golf Association, United States Golf Association (USGA) and the Golf Course Superintendents Association of America attended a First Green workshop on how to host field trips. The workshop is part of First Green’s expansion into the Portland area, and was made possible by a recent grant from the USGA.
For a glimpse at First Green, watch this 5 minute video showing First Green field trips in action. For more information about hosting a field trip, see the First Green website.
Creeping bentgrass (Agrostis stolonifera L.) golf greens infested with annual bluegrass (Poa annua L.) can be hard to manage, unattractive, and have reduced playability. Methiozolin ('PoaCure') is a relatively new isoxazoline herbicide that has shown selective P. annua control in golf greens.
