F R O M T H E T TA P R E S I D E N T Jay Willis
Good Education! Good Times! Good Friends! hope this letter finds everyone doing well and back into a routine after the holiday season. I know I’m ready for some green grass to show itself and get back to business as usual. With some of the coldest temps we have seen in the state since the ultradwarf greens were sprigged in the late 90s, we now should be able to tell how much of a cold tolerance the ultradwarf greens truly have. For those of you that I have not had the pleasure to meet, I would like to introduce myself to you. I am currently the golf course superintendent at Glen Eagle Golf Course
I
in Millington, TN, on the NSA Mid-South Navy base. My family life is the most important thing to me, with my amazing wife, Amy, and our two girls, Mary Grace (age 8) and Sarah Madison (age 6). I am very fortunate to have a family that is supportive and understanding during the turf industry’s long days during the summer. Enough about me! I would like to personally thank Mr. Bob Hogan for the outstanding job he did as president of TTA. Without his leadership and the hours he devoted, the association would not have run so smoothly. On behalf of the TTA board of directors and
the members of the Tennessee Turfgrass Association, we would like to say, “Thank you, Bob Hogan, for your time & service!” TTA had another great conference and trade show this year. Many old friends reunited for their annual get-together. Dr. Tom Samples and his staff at The University of Tennessee organized a great education session. At the trade show, attendees discussed new products and innovative ideas. Our attendance numbers for the Conference and Trade Show were steady with last year’s attendance. The TTA was proud to award the Ernest Hardison Memorial scholarship to Mrs. Gabrielle Wilburn and the TTA Legacy Scholarship to Mr. Joseph Daugherty. Our Turfgrass Professional of the Year was presented to Al Davis of Ridgeway Country Club by his long-time friend Larry Shore, formerly superintendent of Germantown Country Club. The presentation Larry Shore made shows the fellowship that we all enjoy with our colleagues in the turfgrass field. On behalf of the TTA board of directors, I would like to thank the members of the TTA that joined us in Franklin for the TTA conference. We look forward to serving on the TTA board for you this year, and we want you to know that if you have any ideas you would like to share, please don’t hesitate to email or call one of the board members. Sincerely, Jay Willis 2010 – 2011 TTA President

FROM THE TVSTMA PRESIDENT Theo Lankford
New Officers and Great Meeting Locations for 2010 ere we are at the beginning of another year! I would like to thank all of last year’s officers for a job well done in 2009: President Stephen Crockett, Commercial Vice President Dawson Thombs and Secretary/Treasurer Stephen Callis. This year's board members are already showing that they are willing to work even harder to make the best of 2010. TVSTMA’s new board of officers is listed on page 12. For those of you who don’t know me, I am Theo Lankford, and I will serve as your TVSTMA President for 2010. Although things are not looking up for most of us, I believe that by utilizing our network abilities through the TVSTMA, we can
H
create a little brighter light at the end of the tunnel. Our new board is already working very hard to provide the most interesting locations for field days, with the most informational and educational sessions you can use to make the safest and most attractive fields possible. So far, we have confirmed Pringles Park in Jackson for the West Tennessee meeting. For our Upper East Tennessee meetings, we will gather at Danridge Municipal Park in Danridge, and then we will go to Lee University for our Lower East meeting. Finally, in Middle Tennessee, we are working with Ensworth High School in Bellevue. Please be sure to spread the word about the great locations we have scheduled for this year.
Although the board of officers is working hard, we still need your help to make this year a true success. Several committee seats are waiting to be filled. Thank you to those who have already expressed interest in serving on a committee. For those who wish to serve but have not yet notified us, please email me (or one of the other officers). We will be contacting you all very soon. Our emails are listed on our website at www.tvstma.com and on page12. If you are on Facebook, the TVSTMA has formed a group. Here, we can have discussions, and updates will be available for upcoming events. Newsletters have been going out via email. If you are not getting these, please let us know. If you were in attendance for the 2010 Tennessee Turfgrass Conference this past January, I hope you were able to make it to our social that was held on Sunday. I had a great time networking with others in the industry. I hope everyone else did as well. That social would not have been possible without the following sponsors: Southern Athletic Fields, Cumberland Valley Sod, Tri-Turf Sod Farms, Ewing Irrigation, Ladd’s, McCurdy Sod Farm, and Syngenta. If you are a commercial member, the board is putting together new options for you to sponsor our upcoming events. Our Commercial VP, Erin Kinney, will be in contact with you soon. I am looking forward to a great year, and remember that an association is only as good as the participation of the members within it. Theo Lankford 2010 TVSTMA President

CONTINUED espite chilly weather — and the even chillier economy — the 2010 Tennessee Turfgrass Association’s Annual Conference and Trade Show was well attended. Held January 10–12 at the Cool Springs Marriott in Franklin, the highly informative education program (coordinated by TTA’s Education and Programs Committee and Dr. Tom Samples, with The University of Tennessee’s turfgrass program), attracted turf professionals from across the state. Attendees also took advantage of networking opportunities and previews of the year’s new products at the event’s ever-popular trade show. At the organization’s Annual Business Meeting and Awards Luncheon on Monday, TTA president Bob Hogan recognized and thanked this year’s outgoing board members, including Dick Breedlove, Paul Carter, Tommy Mittlesteadt, Mitch Parker, Scott Severance and Doug Ward. Re-elected for another two-year term were Carter, Mittlesteadt, Parker and Ward, while Bob Elliott (Ewing Irrigation) and Chris Simon (Signal Mountain Golf & Country Club) — were elected to fill the remaining vacated two-year slots. In the awards portion of the luncheon, Al Davis (superintendent at Ridgeway Country Club for the past 32 years) received the 2010 TTA Professional of the Year award, which was presented by his longtime friend Larry Shore. Tommy Middlesteadt, chair of TTA’s Nominations and Scholarship Committee, also announced two scholarship recipients. Gabrielle Wilburn (a student at Walter State Community College) was awarded the Ernest Hardison Memorial Scholarship. Joseph Daugherty (son of Joey Daugherty and a student at Murray State Community College) won the Legacy Award, which is available to children, stepchildren and grandchildren of TTA members. The next day, during the TTA board meeting, the following executive committee was elected: Jay Willis, president; Bob McCurdy, vice president; and Paul Carter secretary/treasurer. If you missed this year’s event, be sure to mark your calendars for January 5, 6, & 7, 2011, when the TTA celebrates its 45th

TURF TALK
Winter 2010: The Big Chill By Chris Hartwiger and Pat O’Brien, USGA Green Section
ost of the Southeast experienced a prolonged period of temperatures that were 15 to 20 degrees below average during the first two weeks of January. Many cities have not seen this duration of cold temperatures in decades. Because many courses have converted from bentgrass to an ultradwarf bermudagrass, the topic of winter injury to bermudagrass putting greens has been much talked about this winter. In this article, we will review what we observed in the region and lingering questions.
keep the heat in a putting green rootzone. Superintendents at several courses without protective covers decided to turn on the irrigation water in subfreezing temperatures to ice their putting greens. Some superintendents with covers decided to freeze a thin layer of ice over their covers. We have no idea whether these techniques were effective, but they do raise interesting questions reviewed in the next section.
Observations
1. We know covers help to retain heat in a putting green when deployed as described above. Based upon research at Mississippi State University in the mid-1990s, Dr. Mike Goatley (now at Virginia Tech) observed that for temperature retention, there was not much difference regardless of what the cover material was made of. However, there is a larger benefit when two covers are used. 2. Research in Canada in the mid-1990s and published in the September/October 2000 Green Section Record (“Winter Protection of Annual Bluegrass Greens”) confirmed that a straw layer underneath a cover provides improved protection. See http://turf.lib.msu. edu/2000s/2000/000911.pdf for more information. This confirms field observations seen for many years in the region. 3. More questions than answers remain for icing the putting greens. Theoretically, there is some potential for heat retention, but there is no research data to confirm or deny this concept. Most courses that used this technique did so because they did not have any covers and they used icing as a last resort. We discussed the concept of icing with several turfgrass scientists, and they agreed that concluding whether icing is effective is problematic. Questions, concerns and comments include: • Should an ice cover be used for one event (i.e., a single night) or for multiple
M
A standard recommendation in the region is to cover bermudagrass putting greens any time temperatures are scheduled to fall below 25ºF. The arrival of cold air was forecasted accurately, and superintendents with covers deployed them on either January 1 or 2. Figure 1 shows the duration and extent of the cold air in the Southeast. Temperatures fell to or below 25ºF for almost 14 consecutive days. In fact, this 14-day period was the 8th coldest 14-day period in Birmingham since records have been kept. Most courses kept the covers on for at least 12 or 13 consecutive nights. The consistently cold temperatures kept the labor requirement to a minimum, as there was no need to put on and remove the covers each day. As forecasted temperatures began to dip below 10ºF and the number of days with lows below 25ºF began to mount, superintendents began to contemplate extra protection. Numerous courses in the Memphis, TN, area have double covers that were used for several days. Another idea used successfully was to apply either pine straw or wheat straw and then put the covers over the top. This technique was helpful on shaded greens and/or putting greens with north-facing slopes. Both double covers and straw plus a cover creates a boundary layer of air that has tremendous insulation properties to help 18

Lingering questions and comments
nights in a row? Researching a topic like the influence of an ice cover on winterkill protection is difficult because so many variables besides temperature are involved. • Is crown hydration a concern? Crown hydration is not a good thing for any turfgrass experiencing cold temperatures. If icing is used multiple days in a row, the freezing and thawing of the ice can lead to crown hydration. As crowns become hydrated, the temperature at which they could become injured will increase. Crown hydration may be enhanced if the soil is frozen at the 2" level and doesn’t thaw during the day. The melting ice will have nowhere to go except for some surface drainage. • What is the best thickness of ice for prevention of injury? This is a difficult question to answer, and attempting to answer it brings in confounding questions regarding what the temperature of the ambient air above the ice coating is and how long the temperature stays below freezing. • Because irrigation systems are not uniform, will there be an impact on injury/ no injury? We do know that uniformity is variable and any resulting ice coating will be variable, too. As the calendar moves into March, we will know much more about any winter injury. In the meantime, it might be a good idea for superintendents to take a few plugs from questionable greens and place them indoors in a sunny window. In three or four days, you should know if you’ve got live grass. Please do not hesitate to contact either Pat O’Brien (patobrien@usga.org) or Chris Hartwiger (chartwiger@usga.org) with any concerns about your golf course.

WEED WATCH
By James T. Brosnan, Ph.D., Assistant Professor, Turfgrass Weed Science, and Greg Breeden, Weed Science Extension Assistant, The University of Tennessee ild garlic (Allium vineale) is an odiferous, perennial weed found in various turfgrass areas throughout Tennessee. Although similar in appearance to wild onion (Allium canadense), wild garlic is far more prevalent in Tennessee than wild onion. Wild garlic infestations are most prevalent during early spring, fall and winter.
W
Wild garlic’s life cycle in Tennessee Wild garlic is a cool-season perennial that emerges from bulbs in the fall and grows throughout the winter. In spring, it will flower and produce aerial bulblets that can survive for several years after they are incorporated into the soil profile. After these bulblets are formed in the spring, the plant goes dormant throughout the warm summer months.
Identifying wild garlic Wild garlic typically grows in clumps of several individual plants (Photo 1, above). Slender, cylindrical and hollow, the leaves have a waxy appearance. The foliage produces a distinct odor when crushed. Wild 20
TENNESSEE TURFGRASS
garlic’s flowers produce underground bulblets (Photo 2) rather than seed. Wild garlic is similar in appearance to wild onion, but the leaves of wild onion are flat and not hollow. This is the easiest way to distinguish between the two species. Wild garlic is also similar in appearance to Star-of-Bethlehem (Ornithogalum umbellatum). However, the leaves of Starof-Bethlehem have a distinct white mid-rib (Photo 3) and do not produce an odor when crushed. Additionally, Star-of-Bethlehem produces distinctive white flowers (Photo 4).
Control options Although regular mowing can weaken wild garlic and hamper its production of bulbs, mowing will not eliminate the weed. And, unfortunately, there are no effective preemergence herbicides that control wild garlic in turfgrass. Even postemergence control is difficult and often requires repeat applications of postemergence herbicides. Use products containing 2,4-D alone or in combination with dicamba (see Table 1). Some ALS-inhibiting herbicides (Corsair, Monument, etc.) can
also be used to control wild garlic. Herbicide applications can be made in the fall after re-growth of wild garlic has occurred following the first hard frost. However, most control programs are centered around spring applications, as wild garlic infestations are more widespread at that time. Optimum control can be achieved by annually repeating either early spring or fall/ winter applications. After any herbicide application, if sufficient re-growth of wild garlic occurs, a second application will aid in longterm control. Mowing should be delayed for 10 to 14 days after a postemergence herbicide application to control wild garlic.
Final thoughts Numerous herbicide options are available for control of wild garlic in established warmand cool-season turf. Before applying an herbicide, always read the product label and follow use directions carefully. For more information on turfgrass weed control, visit the University of Tennessee’s turfgrass weed science website at http:// tennesseeturfgrassweeds.org. (Above) Photo 1. Wild garlic foliage.
