We Need

Charlie Y

ou’ve probably seen the Charlie commercials. Farm Bureau Insurance has done a good job portraying farmers as having all the right answers. Charlie has knowledge and wisdom about any situation. I’m proof that being a farmer does not bequeath any special mental abilities. But I’ll also admit that working with Mother Nature can present a lot of situations where we have to figure things out.

The other day, I was visiting with a fellow turfgrass manager, and we started sharing stories about our workday. We compared notes on some of the many questions we get throughout the day. Questions like what to spray for insects, diseases or some vaguely described weed. Others about shade, traffic, water or getting rid of moles.

People expect us to know about things such as sand sizes, tire pressures, blade tip speeds and how big an average-sized yard is. They ask things like, “When should I mow my yard?” and “How much water does my hose put out?” and “Is grass making my dog sneeze?”

We need to know about so much more than grass. We need to know what kind of grubs we have, how long an armyworm’s life cycle is, how to tell if pH is high or low and how many square feet are in an acre.

Being a golf manager, my friend commented that he needed to know things like how many dimples are on a golf ball, what the proper mowing height for an ultradwarf is and

how many carts are needed for next week’s tournament. He also needs to know how to handle every personality on his board and how to keep the membership in awe of his ability.

There’s just so much to learn about soils, pests, construction and even the weather.

How do we go about keeping up with all of this? Actually, lots of information sources are available. Turf conferences (like TTA’s 47th Annual Conference & Tradeshow, January 7–9), universities, the internet, printed material and company reps are all valuable resources. My dad has always told me that experience is the best teacher, but that it is also the most expensive.

But what if we share our experiences with each other? Our successes, as well as our failures, can be a huge benefit to those facing similar circumstances. That is why I think it is important to get involved in trade associations like Tennessee Turfgrass. We need to share with others in our profession. Register today for our January conference in Franklin. It probably won’t make you as smart as Charlie, but you could get close.

From the T VSTM A President

Wayne Treadway

Sharing Information If

you did not attend the TVSTMA meetings this year or the regional STMA meeting, you missed some helpful educational information. I’d like to take this opportunity to share some of the sessions that I thought were outstanding.

Our first meeting was in Huntsville, Alabama, in conjunction with the Alabama Sports Turf Association. The first thing I enjoyed was meeting the people from that area and sharing information and learning from their experiences. Everyone has problems and challenges, and how someone handles his or her challenge may not be the way I would handle the same situation. As someone told me, “Experience is something you get right after you need it.” The more we learn from others, the fewer mistakes we make from our inexperience. The session on fire ant control was especially informative, although fire ants are not yet a problem in East Tennessee (where my fields are located). What I

learned, though, was how hard these pests are to control once they infest your fields.

As the old saying goes, “An ounce of prevention is worth a pound of cure.”

The STMA regional meeting in Cincinnati was outstanding. The location in the club level of Paul Brown Stadium made us all feel like celebrities. (Speaking of celebrity, Joe Morgan just happened to walk by as we toured the baseball stadium.) The meteorologist was the highlight of the meeting. Getting to attend a Reds baseball game with good seats and wonderful food was not bad, either.

Our meeting in Jackson was very informative on disease and insect control. Those topics sometimes take a back seat to mowing and other routine maintenance chores, but if either becomes a problem, a turf manager cannot have enough information.

This was the second time I attended a meeting at the ballpark in Jackson. The 16-field complex is a masterpiece, and the fields are well managed. Even with the hot temperatures and dry conditions, the fields looked beautiful.

At every meeting, I always learn something. The most enjoyable and informative part of each session is meeting other people in our profession and sharing information. If possible, make yourself a promise to attend as many of the meetings as possible. We need each other.

Wrapping Up a

Great Year W

ell, another year is coming to a close and I hope everyone had a successful growing season. I know this year was a long and hot one, but that seems to be the norm now, doesn’t it?

It’s that time again when we, as turfcare professionals, come together to support scholarship and research. This year, we will hold our MTGCSA Scholarship and Research Golf Tournament at the Vanderbilt Legends Club on October 29. We all know how important

Jerry Craven

this fundraiser is to our industry, so please come out and support, play and enjoy the camaraderie that this tournament always brings.

MTGCSA’s educational meeting in April was very informative, and I hope all who attended gained something useful for their pond management, weed control and/or water management. The May meeting about Tier 4 was also very educational. If you missed it, make sure you talk to your equipment salesmen to get the very latest information regarding this major change coming to our industry in the near future.

The “social” at the Lightning Bug was a ball; Bill Blackburn does such a wonderful job for junior golf, and we all should be very proud to be participants. Our last educational meeting will be November 12 at Brentwood Country Club, so be sure to attend to get your points!

This being my last letter to the association, I would like to put out a call to all MTGCSA members to get involved — we need your help on the MTGCSA board of directors. We have several officers leaving posts, and we need new faces to join.

Our board members have given their time and talent, so now it’s your turn! Help keep the MTGCSA strong.

In Tribute

In Tribute to a Turfgrass Giant...Stanley Zontek,

USGA Agronomist

By Hunki Yun, USGA

S

tanley J. Zontek, the director of the USGA Green Section’s Mid-Atlantic Region, passed away August 28, 2012, after suffering a heart attack. He was 63 years old.

The organization’s longest-tenured employee, Zontek joined the USGA in 1971 after graduating from Penn State University. He started his USGA career as an agronomist in the Northeastern Region.

He moved to the North Central Region in 1980 before becoming the director of the Mid-Atlantic Region in 1985.

Zontek, who resided in Avondale, Pa., was a world-renowned turfgrass expert who shared his extensive knowledge for 41 years through articles, speeches and course visits. He helped establish many of the best turfgrass practices still in use.

During his career, he assisted thousands of courses around the world to achieve the best conditions possible, whether in preparation for USGA championships or for everyday play. In addition, one of his responsibilities was helping to maintain the putting green at the White House.

Zontek was recognized for his contributions with many awards, including the 2006 Golf Course Superintendents Association Distinguished Service Award, the 1997 Golf Course Builders Association of America Don A. Rossi Award and the 2007 Crop and Soil Sciences Outstanding Alumni Award from his alma mater.

“Stanley was an icon to all of us personally on the Green Section staff and within the industry,” said Dr. Kimberly Erusha, the managing director of the USGA Green Section. “We have lost a great friend and an influential voice in the game.” T 12

Career Enhancement

The

Value Of

Education

By Stanley J. Zontek, Director, Mid-Atlantic Region, USGA Green Section

Editor’s Note: This article was originally published in the USGA Green Section Record on November 10, 2011. Sadly, Mr. Zontek passed away on August 28, 2012, from a massive heart attack (see previous page).

I

recently heard the comment, “I don’t have time to attend turf conferences.

I’m just too busy.” Ironically, this was stated at a turf seminar!

Here’s the point: I would argue that you should MAKE TIME to attend that conference and, further, bring along your assistant superintendent, general manager, green chairman, golf chairman and anyone else in the club who would benefit from such a meeting.

Here’s why: Although the “basics” of golf course turfgrass management never really change — balanced and adequate fertility, root growth, effective water management, weed and disease control, thatch management, aeration and topdressing — it is the fine points of turfgrass management that are so important to learn and re-learn. At the very least, you can make informed decisions on what is best for you and your course.

With all of the stressful weather that most regions of our country have experienced this year, it is essential that you listen and learn about what worked and what didn’t work. We are in a period of weather extremes, and the best way for your turf to survive is to grow healthy grass.

What’s the new research on whether or not bacteria can actually affect golf turf?

Is this a new problem to worry about?

What’s the latest on control of Poa annua?

What about crabgrass and goosegrass control? Weed control in general… did you fight more weeds this year than in the past? If so, then you might need to change something or add something to your program to resolve the problems you now have. Clearly, what you may have done in the past may not work.

Think about it, do you really NOT have the time to learn ways to solve problems, for a better golf course next year? I would wager that you NEED to find time to attend these meetings.

Education is an ongoing effort. I have been with the USGA for more than 40 years, and I value the time I spend sitting in the audience and listening to all the comments about everything on the agenda.

The older I get, the more time I spend being educated. It makes me better able to answer the questions I am asked, while

staying current with all that is happening in our field. Sadly, I see and know about superintendents who no longer attend conferences and lack that thirst for information. It can change a productive turf manager into one who is less effective. Think about it.

Are you really too busy to sit down and listen to lectures on the industry that we all share? If you think about it, you need to attend those conferences, lectures and seminars. For that matter, bring a colleague or someone else who would benefit. T

47 th Annual

Turf T alk

By James T. Brosnan, Assistant Professor, and Greg Breeden, Extension Assistant, Turfgrass Weed Science, University of Tennessee

The

best defense against weed infestation is maintaining a dense, vigorous, high-quality turf. Although implementing cultural practices to maximize turfgrass quality (proper mowing, fertility, pest management, etc.) will reduce the likelihood of weed infestations, herbicide applications are often required for complete control.

Types of herbicides Herbicides are chemicals that kill or suppress the growth of plants. More than 300 chemicals are used as herbicides throughout the world. They are broadly categorized by mode of action, chemical structure and application timing.

Selective vs. non-selective Selective herbicides control certain weeds but will not cause injury to registered crops (e.g., turfgrass species) when applied at the correct rate and timing. Most herbicides are sold for selective weed control.

22

Turfgrasses listed as “tolerant” on the product label either do not absorb toxic levels or are able to compartmentalize, exclude or metabolize these herbicides so that they are no longer a threat to turfgrass survival.

In contrast, non-selective herbicides will cause damage to most any plant. A commonly used non-selective herbicide in turf is glyphosate (Roundup ProMax™). Nonselective herbicides should be used with caution when spraying around desirable vegetation.

Preemergence vs. postemergence Preemergence herbicides are applied prior to the emergence of the weeds to be controlled. Most of the preemergence herbicides used in turf have residual activity in the soil, entering the roots and/or emerging shoots of weeds, and may be active in the soil for more than 10 weeks after application. Preemergence herbicides commonly need 1/2" of overhead irrigation or

TENNESSEE TURFGRASS October/November 2012 Email TTA at: tnturfgrassassn@aol.com

rainfall after application for “activation.”

Contrary to popular belief, residual herbicides do not prevent seed germination, but instead they prevent weeds from maturing by inhibiting growth processes following germination.

In contrast, postemergence herbicides are applied after weed emergence. Postemergence herbicides enter weeds through the foliage and either act at the point of contact or move systemically through the vascular system of susceptible weeds. As a general rule, smaller, less-mature weeds are more readily controlled than those that are larger. Many postemergence herbicides are applied with an adjuvant in the spray solution to increase control.

Herbicides labeled for use in turf The tables on pg. 25 list herbicides labeled for weed control in turf. Herbicides are often referred to (and recommended) by the name of their active ingredient rather

than their trade name (i.e., the name that appears on the actual product container) because trade names can change over time.

Additionally, products with the same active ingredient may have different trade names, depending on where the herbicide is intended to be used. Lastly, different companies may sell the same active ingredient under different trade names. Sometimes two products with the same trade name may contain different concentrations of the same active ingredient (such as Roundup™).

Remember, to provide effective weed control, a product must control the target weed without injuring the turf in which the weed is established. Before application, always carefully read the label of the product. Herbicide labels are legal documents that must be followed. Labels provide users with specific use information on turfgrass tolerance, weed species controlled and information about where the product can be safely applied. For example, some TENNESSEE TURFGRASS ASSOCIATION • TENNESSEE VALLEY SPORTS TURF MANAGERS ASSOCIATION • Tennessee Golf Course Superintendents Association

23

Turf Talk products are not labeled for use on home lawns, while others are not labeled for use on golf greens. Consult the label to determine if the herbicide selected is labeled for the desired use.

Many herbicides contain multiple active ingredients within a single formulation.

This is especially true with postemergence herbicides for broadleaf weed control.

Often, these combination products will be sold under different trade names, despite containing the same active ingredients.

The omission of a particular trade name is not intended to reflect adversely, or to show bias against, any product or trade name not mentioned. This article is not an exhaustive list of all combination products labeled for use in turfgrass, but rather, it is designed to be used as a guide in selecting herbicides for use in turf, recommended by the name of their active ingredient.
