Why Do They Call It a

Field Day?

W

hen my daughter was in the second grade, her teacher sent home a note declaring that the following Friday would be the School Field Day. Having grown up on the farm, Liz’s thoughts of a Field Day revolved around pulling weeds, stacking sod or planting grass by hand. I could tell that she was troubled by the upcoming event, but she knew that the rest of her class of city kids was excited.

The big day at the park finally arrived, and she went to school with hesitation.

Later that afternoon, I asked her how her day went. With a grin, her response was, “Why do they call it a Field Day?” I’m like Liz. You would think that the UT Turf and Ornamental Field Day would be called anything but a Field Day. There are educational sessions on turfgrass cultivars and pest management. Experts offer tips for managing athletic fields and putting greens. This year, your Tennessee Turfgrass Association will even hold a raffle for an iPad and will operate a Plinko Game, WITH PRIZES! Needless to say, there will also be plenty of opportunities to network with turf professionals from all around the Southeast.

All of this will take place at the East TN Ag Research and Education Center on the UT campus, on September 12, beginning at 8:30 a.m. You should also make your plans to join us for some social networking at Barley’s Tap Room & Pizzeria, located at 200 E. Jackson Avenue, in downtown Knoxville at 8:00 p.m. on September 11.

With so much activity and education, I too wonder why we call it a “Field Day.”

Start with

Good Preparation

A

nother youth baseball season has come and gone. Football season is starting. No rest for the weary!

I look back at the past season and think about what I can do better next year to make the field better. This past spring and early summer combined to create the worst growing season for bermudagrass I’ve experienced. We started with a wet cold spring that continued in east Tennessee through June. There was one silver lining, though. Irrigation was not needed.

I wished I could have reversed the pumps and sucked some water out of the fields.

When the growing season is not optimum, what can a turf manager do? My opinion is to make sure you have done the basic practices, which starts with good preparation. In the winter, make sure all of your equipment is working well, making repairs where needed. Sharpen mower blades, and adjust them to your preferred height.

Also, in winter, take a soil test in all turf areas. It is hard to get where you want to be if you do not know where you’re starting. Soil tests will let you know what nutrients are needed, and if the test is conducted early enough, you can budget accordingly. Make sure the nutrient level is optimum to start the growing season.

As the season begins, keep notes on problem areas. Are these areas caused by poor drainage, over-use, disease, low fertility or insects? This year, I had more problem areas than ever, primarily caused by low areas with poor drainage. I hope to correct these areas before the next season.

One problem often causes other problems. My low, wet areas were susceptible to disease. Over-use, compaction and poor growing conditions kept the areas from recovering before July. Ample aeration

cannot be over-appreciated. Good airflow was a must this past growing season.

Even if you haven’t yet needed to run irrigation, still make sure that all facets of the system work properly. Check pumps, lines, valves, controls, rotors and nozzles.

I’ve learned that if any part of the system is faulty, the turf suffers.

Another area of preparation is education. Attend as many workshops and turfgrass meetings as possible. Learn what’s

TENNESSEE TURFGRASS August/September 2013 Email TTA at: tnturfgrassassn@aol.com

new in the turgrass industry. Share your experience with others, and learn from others, also.

You may not be able to predict what the next turfgrass growing season will bring, but good basic preparation will make it easier to handle whatever problems do pop up.

Two Great

Events Ahead!

We

are quickly moving through the hot, humid summer months, and many of us are looking forward to the cooler days of fall soon to come. Summer 2013 has been somewhat unusual, seasonally speaking. If you are like me and have been at the same facility for several years, you have the opportunity to compare the progress, changes, etc., of your course year to year. I make comparisons such as: the greens were just a little better this year, the rough was cleaner than last year, and things seemed to dry out more in past years. In considering another comparison, I would like to see a show of hands that have experienced a July 4th week with the temperatures we recently experienced. I had prepared for a packed week of golfers, and as I started my morning ride, I made a quick U-turn and headed back to the office. I needed a pullover in July! That was truly something I may never experience again, but I will always remember being “chilled” on a July morning.

I trust you feel as I do in that this year’s MAGCSA meeting schedule has included very educational and helpful topics for our members. As fall approaches, we are preparing for a new and exceptionally important event in our schedule for the season. September 9 is the date for our Scott McNeer Scholarship and Research Tournament, which will be held at Spring Creek Ranch. This tournament is greatly supported, and it enables us to prepare

10

for the next year. Without an event such as this one, we could not make the contributions we are committed to each year.

In years past, we have been able to assist young students with scholarships and to proudly support local research programs from different universities. Thanks to all for the continued support and great tournament participation.

Also, this year we have combined our 3rd Annual Bushwood Classic with a GCSAA National Championship and Golf Classic Qualifier. This event will be held on October 15 at Mirimichi Golf Course.

This is an opportunity for the MAGCSA to be represented in the 2014 GCSAA National Championship and Golf Classic.

All participants will be required to pay a $50 entry fee and must meet all GCSAA requirements to participate, including

TENNESSEE TURFGRASS August/September 2013 Email TTA at: tnturfgrassassn@aol.com

good standing with GCSAA and possessing an active USGA handicap. Participants will compete in both gross and net divisions, with winners of each division being awarded a $500 expense credit and paid entry into the 2014 GCSAA National Championship and Golf Classic. Please mark your calendars for this opportunity to represent the MAGCSA. Again, we are looking forward to great days ahead, with exciting events still on the calendar for our association. Thanks to all our superintendents for their support this year by donating their time and facilities for meetings. Your support makes our association successful! Hope to see you at our upcoming events.

Mobile Weed Manual: A New Resource for Managers of Turf and Ornamentals

By James T. Brosnan, Ph.D., and Greg K. Breeden, The University of Tennessee

H

erbicide selection is an important step in effectively managing weeds throughout the landscape. Individuals caring for warm- or cool-season turfgrasses and/or ornamental plants can face unique challenges in selecting herbicides for weed control. Weeds that persist in ornamental areas are often different from those found in turfgrass stands. Additionally, desirable ornamental plants found throughout the landscape can be quite diverse and thus exhibit variable tolerance to herbicide applications. Lastly, many herbicide products labeled for use in turfgrass are not labeled for use in ornamentals and vice-versa. All of these factors make the process of herbicide selection in turf and ornamentals quite challenging.

What is Mobile Weed Manual?

The University of Tennessee Turf & Ornamental Weed Science Team has developed a new resource to help green-industry professionals meet this challenge.

Mobile Weed Manual is a new mobile website —www.mobileweedmanual.com — to help practitioners select herbicides for use in both turfgrass and ornamental areas (see Figure 1). The site contains weed-control efficacy data and turfgrass and ornamental tolerance information for over 2,300 different species, as well as labels for nearly 100 different herbicides, 18

all of which are optimized to be easily accessible from the palm of your hand.

How does Mobile Weed Manual work?

Mobile Weed Manual will work on any mobile device (i.e., smartphone, tablet, etc.), regardless of manufacturer or operating system. Although the site will also function on a desktop or laptop computer, it was designed for use on devices with touchscreen capability.

Mobile Weed Manual offers users three means of selecting herbicides for weed control (Figure 2).

Search by Herbicide This option is designed for individuals who are curious about which products are labeled for preemergence (PRE) or postemergence (POST) weed control in either turfgrass or ornamentals, regardless of species. How could this be useful? Select PRE herbicides for turf, and the site will list all active ingredients labeled for PRE weed control in turf. Interested in POST weed control in ornamentals? This function will populate a list of all products labeled for such use.

Search by Desirable Species This option is designed for individuals who need to know which herbicides are labeled for PRE and POST weed control

in or around the specific turf/ornamental species that they manage. For example, this option would allow a lawncare professional to view a list of all the herbicides labeled for PRE weed control in tall fescue turf or determine products labeled for POST weed control in a species of Liriope. The opportunities are endless.

Figure 3. The “Search by Weed

Species” function.

Search by Weed Species This is the most powerful function of Mobile Weed Manual. This function allows user to select herbicides to control a specific weed that is growing in a particular species of turf or ornamental planting.

The steps are simple (Figure 3): • Select a use area (i.e., turf or ornamentals).

• Select an application timing (i.e., PRE or POST).

• Select the desirable species (i.e., the type of turf or ornamental planting in which weed control is needed).

• Select the weed type.

• Select the specific weed to be controlled.

These steps serve as filters to narrow down the 100 different herbicides and 2,300 different plant species to best fit the user’s situation. All of these filters must be completed for the site to function properly and provide correct herbicide recommendations. Users will be alerted in the event that they omit required information.

The site will then display a list of herbicides labeled to control the weed selected. Herbicides are color coded by the level of control that can be expected by an application made, according to label directions (Figure 4).

These rankings are based on the results of research trials conducted at the University of Tennessee. It is important to note that it is impossible to research the efficacy of every herbicide for control of every weed that could possibly invade a landscape. Thus, herbicides coded gray are labeled for control of the weed selected but have not been evaluated in research trials at the University of Tennessee (Figure 5).

Users can select a particular product from the list to access additional information about how to best use this herbicide for weed management. Mobile Weed Manual will display a page that provides users information on the full array of turf and ornamental species listed on the product label, suggested application rates and remarks and precautions to adhere to before applying the product

herbicides corresponds to expected levels of control.

(Figure 6). Lastly, this page will contain links to each product’s label and material safety data sheet (Figure 7). It is always the herbicide applicator’s responsibility, by law, to read and follow all current label directions for the specific herbicide being used.

How to Access Mobile Weed Manual Using the internet browser on any mobile device, simply visit www.mobileweed manual.com. We recommend that users bookmark the site and create a shortcut to it on their home screen (Figure 8). Directions on the Mobile Weed Manual home page can guide users through this simple process. Creating a shortcut on the home screen will facilitate faster access to Mobile Weed Manual content in the future.

At the current time, Mobile Weed Manual is a free resource. Should users find value in the content provided, they can donate funding (in an amount of their choosing) to support the continued development of this new weed-control resource.

Donations can be made by selecting the “Support” button on the Mobile Weed Manual main page (Figure 9).

Impact The University of Tennessee Turf & Ornamental Weed Science Team hopes that Mobile Weed Manual becomes a valuable tool for all green-industry professionals. The site will be updated continually to expand the database of turf, ornamental and weed species information, as well as to include information on new herbicides entering the marketplace.

Since debuting online in May 2013, the site has been used by individuals managing turf and ornamentals in all 50 U.S. states and 72 countries worldwide. Our hope is that Mobile Weed Manual use expands even further in the future.

ithout research from university turfgrass programs, turf managers of all kinds would be at a huge disadvantage. Fewer new cultivars with improved performance would be developed, and information essential to managing turfgrass pests, using plant growth regulators, selecting the proper rootzone material, optimizing fertilizer applications and other vital issues would be limited or unavailable. The bottom line is that the turfgrass industry as a whole benefits from ongoing research, and advancements would not be possible without it.

In an age of instant information shared via newsletters, blogs, Facebook and Twitter, however, we are often too impatient to wait for science to tell the full story, and instead we opt to hold faith in the word of others. Unfortunately, the purported success of a product is often attributed to the anecdotal findings of one or more people and not based on actual research results. That’s not to say that “perceived” benefits aren’t in fact true, but without sound scientific research, it’s impossible to say.

Let’s take a look a closer look at some of the ways research is conducted and reported. Reported results may come

22

from anecdotal observations or sophisticated, controlled experiments. Regardless of what data you use to make your decision, it’s important to understand the differences in research methods, and it’s essential to understand how to critically review and interpret the results put in front of you.

Anecdotal Although often used as a basis for a product’s success, anecdotal information is simply a report or story from an individual or group. For example, a superintendent may attribute the success of the course’s healthy greens in a given year to his or her use of a new product. Unfortunately, many other factors (Mother Nature being a primary one) may have contributed to the improved turfgrass quality.

Without a comparison, it’s impossible to determine the cause for the improved turf.

Testimonials based on anecdotal reports are often used in advertising or promotion of a product. Such claims, however, can be accepted as truth only with the support of stronger evidence, usually scientific in nature. This doesn’t mean that the information isn’t true; it just means that it has not been proven or subjected to rigorous

scientific analysis. Unfortunately, many companies have significantly larger advertising and marketing budgets than the funds they set aside for research.

The board method Although not considered a true scientific evaluation, using the board method can, at a minimum, help you see what would have happened had you not applied a specific product. This process simply involves spraying over a piece of plywood set on the ground. This untreated area can serve as a side-by-side comparison of the treated vs. untreated turfgrass.

A great example of where this may be useful is in pest control. Let’s say that a superintendent switched to a new preventive fungicide for his anthracnose control this year and reported excellent control.

My first question would immediately be,

Replication in a research trial is important in order to be able to determine true statistical differences among individual treatments based on experimental error.

“How severe was the disease pressure?”

Without an area of turf left untreated, it’s impossible to attribute the reduction in disease symptoms to the fungicide application, since it may have simply been due to a lack of disease pressure this year versus last. Many golf course superintendents utilize this method to evaluate the efficacy of their applications.

Scientific research trials The true test of whether a product or method works is the conducting of one or many scientific experiments. A research program is generally a well-organized effort by a scientist and is designed to gain a better understanding about a specific subject. At Penn State, each faculty member has his or her own research program involving specific areas of emphasis (e.g., nutrition, soils, pathology,

weed control, etc.). The research conducted involves numerous experiments (sometimes spanning an entire career) conducted by the faculty with the help of graduate students, technicians and others.

Experiments can be defined as “investigations that establish a particular set of circumstances under a specific protocol in order to observe and evaluate implications of the resulting observations” (Kuehl, 1994). A basic example of a comparative experiment would be the evaluation of various fungicides for the control of a specific disease. The individual fungicides included in the experiment serve as the treatments for comparison. An untreated control is also an essential component and serves as a standard to evaluate the efficacy of the fungicides evaluated.

So, that’s it, right? We can just spray an area with a fungicide and call it science?

Not really. The details are a little more complicated than that and involve a better understanding of experimental error, research design and statistical analysis.

Although I won’t go into too much detail regarding all of these factors, I do think that it’s important to at least touch on a few important components.

Experimental error represents the “variation among identically and independently treated experimental units” (Kuehl, 1994). Using the comparison fungicide experiment example above, the experimental error would refer to differences in the percent anthracnose within individual plots (also known as a replication) treated with the same fungicide. These differences could be caused by a number of things, including: • Natural variation within the study area • Variability in measuring the response

App lied R esearch • Inability to reproduce treatment conditions from one plot to the next • Interaction of treatments and experimental units • ANY other outside factor that influences the study Using specific data from one of my disease trials last summer, I observed differences in dollar spot severity in my untreated plots, ranging from 151 to 221 infection centers (Figure 1, at right).

Although the reported average on that rating date was 169, all data from the four replications of that treatment are needed in order to determine if significant differences exist among all treatments being evaluated.

Why is this important? This is the primary way for you as the decisionmaker to determine whether one product is better than another.

To explain this point, let’s use the following data from two disease studies at Penn State. Look at the level of dollar spot control shown in Figures 2 and 3, and decide which fungicide you think is providing the best control in each study. When you have decided, continue reading.

Now for the answer. First, the figures are exactly the same. The only difference is that I rearranged the treatment names so that the data is associated with different fungicides. Using Figure 2 for reference, the fungicides providing the greatest dollar spot suppression (based on statistical analysis) are Fungicides 1, 2 AND 3. Due to the natural variation of dollar spot within the study area (refer to the discussion above and Fig. 1), statistically there is no difference in disease control between Fungicide 1 (<1 infection center on average per plot) and Fungicide 3 (an average of 21 infection centers per plot). The differences in the number of infection centers can’t be attributed to the fungicide treatment, but rather some other unknown factor.

So, how are you supposed to know this? Let’s take a look at Figure 3. In this figure, we can see letters above the means for each fungicide. Any data you see in an advertisement or in a presentation should

Figure 1. Natural variation in the level of disease within the study area can be seen in the number of dollar spot infection centers within each of the four untreated plots. All plots were treated exactly the same way (no fungicides, same cultural practices, etc.), but dollar spot infection centers ranged from 151 to 221 spots per plot.

include some information that allows you to determine statistical differences among treatments. The letters that I used in the figure allow you to determine what those differences are. In this example, all fungicides labeled with the same letter are providing an equivalent level of dollar spot control.

In this trial, the untreated control had the greatest number of dollar spot infection centers (DSIC). Fungicide 1 had significantly fewer DSIC than the untreated but significantly more DSIC than all other fungicide treatments. Fungicides 2, 3, 4 and 5 have varying levels of DSIC. Fungicide 5 provided a similar level of suppression as Fungicide 2 and 3, but signif-

icantly less than Fungicides 4 and 6. Fungicides 2 to 4 provided equivalent levels of control, as did Fungicides 3, 4 and 6. Fungicide 2, however, did not provide as much dollar spot suppression as Fungicide 6.

Many would say that Fungicide 6 provided the best control of dollar spot, but this is incorrect. If you were looking for the “best” fungicides based on this data, you would select Fungicide 3, 4 or 6, which all provided a statistically similar level of disease suppression. These separations are based on the least significant difference (often referred to as the data’s LSD). The LSD for this data was 28.09 — therefore, ANY fungicide treatment

that had a mean number of infection centers within 28.09 of another treatment provided similar levels of dollar spot control.

Final thoughts I hope this information will help you better understand some of the fine details of conducting research and the reporting of results. Proper interpretation of data from research experiments will help you select products and implement cultural practices that are best for your turf and also your budget. Although interpreting data can be confusing at times, it is important to keep this information in mind so that you can make informed decisions based on the available research. T

Professionalism and the

Turfgrass Manager

By Michael Goatley Jr., Ph.D., Professor and Extension Turfgrass Specialist, Dept. of Crop and Soil Environmental Sciences, Virginia Tech

It

was my privilege in 2012 to address two professional audiences in locations and settings that mean a great deal to me based on how my career as a university faculty member developed.

In late May, I visited with the Alabama Golf Course Superintendents Association chapter at a meeting in Tuscaloosa where Gib Fox, the director of golf at Ole Colony Golf Course, was one of my Mississippi State students. I saw many of my former advisees in Tuscaloosa, and most university faculty members will tell you that one of the most rewarding aspects of being a university faculty member who works one on one with young people is having the opportunity to watch their growth, both professionally and personally.

Then, in early June, I returned to my hometown of Springfield, Ken-

26

tucky, to address the Kentucky Sports Turf Managers Association chapter.

The KSTMA executive secretary is now Dr. A.J. Powell Jr. (my advisor and mentor at the University of Kentucky), and their current president is Marcus Dean (sports turf supervisor at UK and, like me, a graduate of Washington County High School).

Neither of these venues will mean that much on my annual evaluation, but they were very important for me, as they allowed me to say thanks, renew old acquaintances, make some new friends and, I hope, inspire another WCHS graduate to enter the world of turfgrass management. Plus, my dad (Mike Goatley Sr.) got to be in the audience in Kentucky and see first hand a little bit of what it is that I do in my job as an Extension turfgrass specialist at Virginia Tech.

TENNESSEE TURFGRASS August/September 2013 Email TTA at: tnturfgrassassn@aol.com

What made these talks a little different from others is that each had significant components of my “words of wisdom” outside the realm of turf (as I seem more prone to do, the older I get… my kids tell me this carries over into my parenting techniques, as well). For the KSTMA chapter meeting, my topic was entirely dedicated to professionalism. This is certainly not a typical subject for an agronomist, but it is one that I decided to tackle as an “I can do this” presentation.

My wife, Lisa, is a licensed professional counselor, and she gives these types of talks all the time. She had a worksheet on professionalism already developed, but she encouraged me to ponder my own concepts of professionalism in our industry before reviewing her materials (her list is presented as the last part of this article).

So, here is Mike Goatley’s

top 10 list on

“Professionalism and the Turfgrass Manager”:

1.

rofessionalism means P “giving your best.”

It doesn’t necessarily mean “being the best,” but instead it requires you to put your best effort into everything you do.

2.

Be yourself.

It is pretty easy to spot a phony, and I think it is important to remain true to your identity, values, etc. There are times and places, though, where we must consider our surroundings and how we present ourselves and our opinions. I remember two quotes heard over the years: “You only get one chance to make a first impression,” and “It’s great to be yourself, as long as your self can pay the bills.”

3.

Respect everyone.

Every person I encounter has skills, talents or knowledge that I don’t have, and there is always something to learn.

4.

Professionals are good listeners.

Slow down, and L-I-S-T-E-N.

5.

Try to keep “the job” away from home.

Find and/or make time to unwind from the stresses of your job somewhere away from your family.

6.

Don’t be afraid to resolve conflicts.

Address problems promptly, rather than waiting for problems to take care of themselves.

7.

stablish a reliable E network of professionals.

Keep growing that network — from within and outside your industry — as much as possible.

8.

se professional terms U when speaking.

This goes a great way towards improving the perception of others regarding your profession and job. For instance, you are a “golf course superintendent,” not a “grass cutter.” You are a “sports turf manager,” not “the guy that drags the dirt.” Don’t hesitate to throw a little scientific terminology into the discussion when the opportunity presents.

9.

Give something back.

It doesn’t necessarily have to be money (although there are some great initiatives to fund), as your time and attention to others are frequently more valuable than any financial contribution. I recall a homily at church given by our deacon (and professor of agriculture economics at Virginia Tech), Mike Ellerbrock, regarding paying your “social mortgage.” Deacon Mike’s point was that you should not feel guilty or the need to apologize for having a successful career, a great family, a nice home, etc. What you should try to do, however, is to find some way to make payments on your social mortgage by doing something beyond the minimum for your profession, your church, your community, etc. I am always asked, “So, Goatley, what is your social mortgage payment?” My wife and I teach sacramental preparation for the 2nd grade CCD class at St. Mary’s church. I used to think it was tough teaching college students, but I have learned otherwise. I have developed a whole new appreciation for grade-school teachers.

10.

Put your resources to work.

A lot of topics aren’t necessarily our favorites when it comes to paying attention: labor issues, budgetary issues, environmental issues, etc. Often, however, professionals within your organization are staying abreast of these topics for you.

My top 10 tips and thoughts on professionalism are certainly in no particular order, and I know that you could easily come up with many others of more importance to you. The following details a more complete listing of tips for professionalism from Lisa Goatley’s background in counseling services. I am pleased to see some overlap in my list and hers, as it suggests that maybe I have been listening over the years!
