On Wednesday April 6,
legislative action, H.F. No. 3231, an omnibus bill, was introduced with an amendment sponsored by Representative Jennifer Schultz, DFL, Duluth stating “A person must not apply a pesticide in the following pesticide classes to the property of a golf course: organophosphates, neonicotinoids, carbamates and synthetic pyrethroids.” If passed, this would have eliminated most of the insecticidal tools we would have at our disposal to combat the various pests that can occasionally or in some cases consistently ravage our golf courses. The amendment was added very late in the process as to try and get passed without much notice. Luckily for golf courses everywhere, the MGCSA’s watchdogs caught it. Two important sources emailed MGCSA Executive Director Jack MacKenzie Wednesday evening alerting him, and us, that this amendment was included and would be considered very soon.
The first was David Flakne, a friend of Jack’s who happens to work for Syngenta as their Senior Director of State Affairs, followed closely by Doug Carnival, a lobbyist for the MGA who has worked with the MGCSA since the phosphorous issue rose its ugly head 11 years ago, thanks to the efforts of Jack and the MGCSA combining with the MGA, CMAA and other golf institutions on matters concerning the legislature and government. The first thing Jack asked was what can I do to abate this awful amendment? Carnival responded get down here and be ready to testify on your behalf the next morning at the House Agriculture Policy Committee Meeting, which Jack did. Jack’s telling of our side of the industry, why we need the chemistries listed in the amendment and the relative safety of these chemistries helped get the amendment stricken from the bill. Had he not been there, had Carnival not been looking out

There are two very important points I want to make clear from all of this: 1) This is not, and will not be an isolated incident. This attempted legislation came out of the blue, and there is no reason to believe there are not factions out there planning to get legislators on board for these kinds of bans in the future. 2) The importance of having connections like Carnival, partners like the MGA and a committed Executive Director like Jack MacKenzie is critical. Not just hey great job, not just oh that’s nice we are poking our noses in the process, but critical that we have a vigilant eye on what is going on at the State Capital and with the state agencies so that our business, our means to protect our golf courses, can remain intact. There is no greater evidence than the events that transpired this week. For anybody who uses these chemistries on their course, or Page 8
Unless you have been living under a rock, or never read this magazine before, you probably already realize that Jack is committed to this kind of work, and has forged many alliances with golf partners, environmental organizations, government agencies and the like. You have probably heard one or more of his speeches on our continued water BMP program, or his pollinator efforts, or just his “good story of golf.” His efforts are continually reaping rewards for this association, and this incident proves it. Your membership to the MGCSA has never been more important, nor has it ever truly benefited you like the present. The best is yet to come, both fortunately and unfortunately. In this case, what we didn’t know wouldn’t have hurt us, but definitely would have tied one arm behind our back in our daily fight.

worked and specific equations. Unfortunately for my summer vacation plans, mediocrity in numeration concerned my mother to the point where I went unhappily to math tutoring, very unhappily, in the months of June, July and August of 1972. Arithmetic and I were never going to be friends and I have come to rely upon the calculator to enhance my computing inadequacies.
Take a moment and consider the following ideas. Seriously, clear your mind of whatever it is that could be occupying your brain for the next ten minutes and consider the possibilities. What if, during your life of ups and downs, learning advancements and challenges, triumphs and setbacks, rather than focusing your time and efforts on correcting your deficiencies you instead concentrated upon what you absolutely and naturally succeed at or perform the best at? How much energy and thought have you spent working on a skill that never did, nor ever would, come naturally and how many opportunities to really accentuate your positives have been potentially squandered?
On the other hand, I have always been an avid reader and enjoyed writing, science, teaching and the process of thought. Some would say that these natural traits are my strong suit and their application fit my personality like a glove. Sadly, beyond complacently doing very well in these topics in school, I never pushed myself to wax my organic talents until they shined. My efforts were all too often focused on overcoming the poor performance of my unnatural tendencies.
As a child, I stunk in math. Oh, to be honest, I got by on a limited knowledge of how figures

amount of time trying to get really good at things that I just wasn’t genetically predisposed to conquer. This attempt to be great at everything was actually an anchor preventing me from becoming exceptional at my naturally talented interests. Adding to the frustration are my memories of strongly encouraging each of my kids to be better than average in areas of interest that they may never excel in, rather than encouraging them to hit a “grand slam” in topics that they have the potential to reign supreme. Who knows where my family would be if we had concentrated on our strengths. And achieving that incomparable level likely would have been great fun to do. On the other hand, the leadership program has been very gratifying, as it has empowered me to pursue, guilt-free, my expertise in areas that bring me pleasure. It has prescribed an acknowledgement that I really am poor at a number of skills, but not to worry as long as I have some degree of competence or know the tools to temper my
deficiencies. Consider your life, as an individual, a spouse, a subordinate and a boss. What if you could be adequate in many things but truly outstanding in specific areas by applying your natural strengths? Imagine the “what ifs” had you focused hard on something you were organically skilled at and enjoyed doing. Contemplate how efficient your work team can be if you were to assess individual strengths and partnered your employees based upon harmonic talents instead of throwing a bunch of uninspired individuals together with your desired outcome as the goal. What would be a more efficient use of your labor budget? What would generate a superior end product? I encourage you to pause and think about the things that you are really great at and what it is that you do that brings you great joy. Perhaps you will find that both are mutually inclusive.

some years. Given our positions, it would not have been unusual on the Thursday morning of Masters Week to find Kerry and I spending 30 minutes talking about Ryder
Cup prep. However, the location of our meeting was a bit of a fantasy. As the first few groups of the 2016 Masters were introduced on the first tee, Kerry and I chatted about 100
yards away, just behind the 10th tee. We talked about plans for his next visit, the tree work completed over the winter and a couple of options in regard to raking bunkers between Page 19

staff member will be able to quickly handle the request. In order to keep things efficient and hopefully limit mistakes and oversight; I have, as much as possible, tried to remove myself as the middleman when it comes to many parts of our Ryder Cup prep. A contractor request coming to me, then has to be relayed to a member of the staff. I have no shame admitting this need for relay creates an opportunity for me to forget to pass along the message. Sometimes as superintendents, the best thing we can do is to give our staff the resources and information they need, then get out of the way
and let them do their job. Removing myself as the middleman between PGA contractors and our staff seems an easy way to avoid mistakes. The initial infrastructure build will take place in areas off the golf course. Only after the Hazeltine Invitation, the third week of June, will contractors begin building on the golf course. In only one area of the build have I made a request for specific timing. This request involves our turf nursery. Our entire nursery, located to the left of Hazeltineâ€™s 7th hole, will be covered by a chalet village. I have worked with PGA

in close proximity to this road will allow for much safer spectator egress each evening. In order to prepare and avoid confusion, the Club will be playing the Ryder Cup routing for the entire 2016 golf season. One of the most frequent questions I get is; “when will you be closing the course?” We have only two real limitations on play for the 2016 golf season. Beginning on August 1st, all players will be required to play all fairway and par three tee shots from a 6x18” mat of artificial turf. Each player will carry this mat will them as they play the course. If their ball comes to rest on the fairway turf, they must pick it up and play the shot from the mat. Our goal in using the mats is to stop the accumulation of divots and begin allowing them to heal during the month of August and early September. After Labor Day, the course will close to all play, excepting any participants. This will give us three complete weeks of prep prior to Ryder Cup
week and plenty of time to heal from cart traffic and any remaining divots. Given about eight weeks of healing time, we expect the putting surfaces, tees and fairways should look virtually untouched by Ryder Cup week. My first three seasons at Hazeltine have focused on the development of an agronomic program of bentgrass promotion and management. Our goal was the creation of a program we felt would be replicable in 2016. I feel very comfortable that we have accomplished this. This agronomic program is one of simplicity and despite the magni-
tude of the event, I have no intent to add layers of complication to our agronomics for the 2016 season. The biggest change to our program will come in the area of fall plant growth regulator (PGR) usage. As a default, I usually stay on our PGRs at nearly mid-season rates right through September; in order to keep Poa from gaining any ground during the fall. This PGR use, combined with the cooler weather and shorter days, leads to a drastic reduction in growth. A reduction we compensate for by greatly limiting our fall mowing. Obviously the Ryder Cup, falling at the end of September/ beginning of October, is going to require daily mowing for the better
part of a week. In-turn, our use of PGRs will be the one area in which our agronomic program is drastically different in 2016. Beginning near Labor Day, I plan to remove all PGRs from fairway surfaces. Tees and greens will likely be reduced by 50-75%, then built up again as/ if needed. By rule, I do not use Primo in our program. However, I do expect to use some Primo, as/if needed on all surfaces, leading up to the event. Since the course will be closed in September, we will be able to handle any flush of growth when coming out of regulation, with frequent dry mowing. This flush should also allow for any remaining divots to be completely healed. As we go

combined with a need to complete work in a tight timeframe, demands the need for a golf course maintenance team of 100-plus. I have had a chance to experience the volunteer effort at a number of Majors and I can tell you the experience is like nothing else in the golf business. Our hundred plus people all coming together with the common goal of making a golf course the absolute best it can be is fun, rewarding and energizing all at once.

this event is over, Iâ€™ll be able to add fundraiser to my resume. During my visit to Augusta, what struck me as the difference between the Masters and other Major Championships was the attention to detail. By no means does that mean attention to detail is lacking at other Majors. The advantage the Masters has is they do it every year. The evolution they have been able to achieve by learning from that they did the year before is something we all put to good use at our facilities. I had the great fortune to spend 15 minutes chatting with Augusta National Superintendent Brad Owen. Brad flat out said as much;
“We’ve done this for 60 years and the natural evolution of doing so has allowed us to achieve the levels we achieve.”

I am very much looking forward to putting all of these people together for a fun and rewarding week of golf course prep and camaraderie. In addition to Ryder Cup week, we will be looking for volunteers to help us during the three weeks of closure. This will be an opportunity to expand the number of MGCSA members who are able to experience the Ryder Cup. More
information on pre-Ryder Cup week volunteering will come as we move through the summer. I feel very fortunate as a golf course superintendent to have this opportunity. The very best I can do in my role, is to make sure my friends, colleagues and co-workers who are a part of this wonderful event, feel they were integral to the eventâ€™s success.

Troubleshooting Single and Multiple Valve Irrigation Circuits By Andrew Lindquist, Link Systems Inc.
This article is the first in a series of articles presenting the basic principles of using a voltage-ohm meter (multimeter) in determining the electrical condition of an irrigation system. Although there are numerous respectable electrical testing devices available for irrigation system troubleshooting, a multimeter can provide specific measured values that assist you to decisively determine the type of the electrical trouble(s) that exist. This article assumes that you have a basic understanding about the types, applications, and safe use of a multimeter. If you need a refresher, there are several good online instructional videos availableof which I would recommend the following YouTube video as a place to start: https://www.youtube.com/ watch?v=9IZUvTyOGAk . The Irrigation Circuit: In this article, we will be troubleshooting a simple five station Page 30
(circuit) conventional irrigation system. Troubleshooting systems that use direct current (DC) valves and two-wire system will be presented in subsequent articles. Of the five station circuits available, we will be analyzing only the first two circuits. As shown in Figure “A”, Terminal (Circuit) “1” contains one electric valve and Terminal (Circuit) “2” contains three electrical valves wired in a parallel configuration. ( ) Connecting these valves in a parallel configuration will cause all three valves to energize simultaneously when Terminal Circuit “2” is activated. All valves in the system are electrically identical – each having 30 ohm of resistance and drawing 0.9 amps when activated by the irrigation controller’s 24 volt alternating current (AC) output. ( ) Our multimeter troubleshooting process is to establish expecta-
tion of what the electrical characteristics should be for an intact/perfect system, and then compare these expected values to the system’s actual electrical characteristics. A great advantage of using a multimeter to troubleshoot is that the resulting expected value vs. measured values will provide ideas as to the repair action(s) that may be required. Figure “A” provides us an “as-built” (an accurate representation of the
system) to reference as we troubleshoot this scenario. Having an accurate as-built is a somewhat rare but valuable troubleshooting aid. Referencing Figure “A”, we will structure the expected vs. actual observations and reading into three steps: (1) Analyze the system as a whole (2) Analyze the controller (3) Analyze the system’s wiring and components.

Selection Determines the Quality of Your Workforce By Dr. Bob Milligan, The LearningEdge
With this year’s NFL draft a short time away, sports pages and sports talk shows are buzzing with speculation about draft choices. Why do NFL teams spend millions of dollars preparing for the draft, and football fans become almost fanatical about it? The answer is that this is selection for NFL teams, and the choices determine team quality and success in the future!
the NFL draft a little further. Do NFL teams look only at the skill levels and past performance of the players? The answer is “NO.” They look also look at what is often called “fit.” There is the oft recalled 1998 draft where based on past performance and skills, everyone said the first two draft choices would be quarterbacks and the choice was difficult because the two had almost identical skills. The Indianapolis Colts, with the first pick, carefully Selection is when you choose studied many personal traits, includthose who are going to become members of your maintenance staff ing using sports psychologists, in - your team!

Selecdates have been recruited, selection tion matters! becomes crucial for you course, just as it is for NFL teams. In selection we need to look at more than experience and skills. Let’s pursue our analogy with This notion of “fit” has two dimen-
sions. The first is related to whether the skill set is what is needed for the course. Back to football, teams focusing on passing the ball will look for lineman whose strength is pass blocking.
Diversity is critical to every course; respecting diversity and avoiding any type of discrimination is paramount.
The first key to selection is knowing what you are looking for. The second part of “fit” is fit with your golf course maintenance Taking into account the job staff culture. Does this candidate description and the necessary “fit,” have the personal values, interests, carefully identify and articulate the and career goals that will enable him three to five most important “comor her to contribute to and thrive in petencies” to succeed in the posiyour course culture? It is crucial tion. Competencies are the skills, to recognize that culture fit is NOT knowledge, experience, perforhiring someone who is just like us. mance behaviors, and personal at-
tributes required to succeed in this position. How then do we select the best candidate? Selection involves choosing from the pool of candidates the individual or individuals who best match the competencies needed to succeed in the position. Remember that you are a) determining the qualifications, potential of this candidate for the position, and “fit” with the course and its culture; AND b) promoting the position and your course so the candidate is likely to accept should you offer him/ her the position.
The selection process involves many steps, typically the following: • Review of resumes and/or application forms • One or more employment interviews • Testing, assessments and simulations • Reference checks and recommendations • Hiring The heart of selection is the interview. Here are some ideas to ensure you are prepared for and have a
constructive interview: • Recognize that an interview is an important, stressful event that requires significant structure • Construct a schedule for the interview • Make certain that the candidates fully understand in advance what to expect - anything he/she should bring or prepare, interview time (start and end), interview location (the golf course maintenance facility is not always easy to locate), interview schedule, and format including appropriate dress • Make certain that there are no interruptions during the interview. You must make every effort to make the candidate feel comfortable. Give the candidate many opportunities to ask questions. • Make certain the candidate knows exactly what to expect when he or she leaves the interview.
by writing a series of questions for each of the competencies. Make certain you have different difficulty levels in the questions. You learn a lot both from questions that the candidate can easily answer and those that he or she finds difficult or even impossible to answer.
What and when is the next step.
A prepared set of questions to be asked of all candidates is a unanimous recommendation of all interviewing experts and practitioners. How, then, do we write good interview questions? You should begin
The MGCSA would like to thank Dr. Milligan for his leadership series and professional support. Dr. Bob authors the LearningEdge educational programing.
Many of us have a tendency to ask question that begin with “what would you do if ...?” Research and interviewing experience has shown that a better question begins with “tell me what you did the last time this happened ...?” A concluding remark: Just as a football team greatly influences the future success of their team on draft day, you are influencing the future success of your golf course every time you select a new member of your team - your workforce! Full steam ahead.
Wetting Agent Influence on Surface Firmness and Winter Injury of Putting Greens Sam Bauer and Dr. Brian Horgan Wetting agents are tools that many golf course superintendents use to manage soil moisture. Recently, there has been an increase in wetting agent product claims that their use improves surface firmness and reduces winter injury; however, research on these benefits is limited. We are aware of only three additional research projects that have assessed wetting agent influence on surface firmness of putting greens, and there are no research studies that have evaluated the impact related to winter health. The three firmness study results have not been published in peer reviewed literature. In 2007, Moeller et al. found no differences in the surface firmness
of putting greens following the application of three commercially available wetting agents. Dr. Doug Karcher (U. of Arkansas) also evaluated the influence of eight wetting agent products on the surface firmness of putting greens in Arkansas and found no differences in firmness based on treatment (unpublished data). He concluded by saying, â€œ(wetting agents) appear to have little effect on putting surface performanceâ€?. Most recently, Nangle et al. (2015) studied firmness effects of four wetting agents on a creeping bentgrass putting green in IL, finding no differences.
The winter benefits of fall-applied wetting agents have not been documented in research. Winter injury of turfgrasses can occur due to several mechanisms, including desiccation, crown hydration, suffocation and anoxia, direct low temperature injury, and low temperature fungi.

Applications were initiated in early-May of 2015 and applied through mid-October on four week intervals. Spray volume was set at 2gal/1000ft2 and all treatments were immediately watered in with 0.25 to 0.35 in of water. The treatment area was fertilized weekly at 0.10 lb N per 1000ft2. Plots were mowed at 0.125 inch five times per week. Supplemental irrigation was applied only when plots reached a
volumetric water content threshold of 6% (this never occurred in 2015). Plots were evaluated weekly for: − Turfgrass quality (1-9 scale, 6=minimum acceptable): density, uniformity, color and leaf texture. − Volumetric water content (VWC) (TDR 300, Spectrum Tech): average of 5 measurements per plot to 4.8 inches. − Surface firmness (Clegg Impact Soil Tester 0.5 KG model, Lafayette Instruments): weight dropped 4 consecutive times in the same place and

Results: Surface firmness In 2015 similar trends were observed in terms of surface firmness compared to 2014, although some products had different firmness characteristics from year to year. We also saw greater statistical differences in product performance in 2015 and this could be attributed to better surface consistency across the trial area. The growing season of 2015 included frequent precipitation and VWC never dropped below 12% across the trial

low depth, the untreated control had the longest time to penetrate at 31 seconds (Figure 4).

At 0.39 inches, Duplex and the untreated control had the longest time to penetrate (> 50 seconds) and all other wetting agents tested below 15 seconds. This indicates that the Duplex treatment was not persistent into the spring. At the 0.98 inch depth, Revolution had the fastest penetration time (Figure 3).

penetration times were faster in 2015 and this is likely due to the lower levels of thatch in the trial area. One interesting observation- the products with the highest application rate (Fleet 8oz, Revolution, 6oz) tended to show the greatest persistence, and a low rate product like Duplex (1oz) was the least persistent. This observation leads us to suspect that spring residual is likely impacted by application rate. Conclusions Results from two years of wetting agent trials indicate that surface firmness is influenced by wetting agents, although results are inconsistent and may vary by season and surface type. General correlations were made between surface firmness and volumetric water content (softer = more moisture), but moisture data was never significantly different between treatments. Late-fall applications of wetting agents appear to persist in soils the following spring for a majority of the products tested, as residual wetting agent was found in the upper 0.98 inches of the soil profile. Turfgrass quality and chlorophyll index were rarely improved with wetting agent applications and this may be due to minimal hydroPage 50

A New Face at the U of M: Jonah Reyes Joins the Turfgrass Science Program By Sam Bauer Recently we said farewell to Matt Cavanaugh as he transitioned back to the life of a superintendent working with Dale Hiebert at Rush Creek Golf Course in Maple Grove. We would like to thank Matt for his hard work and dedication during his time with our program and we wish him all the best. Jonah is a local to Minnesota and he received a B.S. degree from the University of Minnesota in Environmental Horticulture. After graduation, Jonah worked as a Landscape Foreman in Hawaii, followed by an eight year tenure as an Irrigation Foreman working on the St. Paul Campus. Jonah is a high energy guy and is very knowledgeable about turfgrass management. We look forward to working with Jonah. In Jonah’s own words: “My passion for the green industry began at a very young age, learning the hard way. With a tile spade in hand I innocently agreed to dig out the entire boulevard of grass so my mother could plant flowers. I was unaware of the value of hard work at the time, but have grown to appreciate it after 20 years in the industry. During high
school I worked for a couple of landscape companies, and then traded in my spade for a degree. I graduated from the U of M in 2002 with a bachelor’s degree in horticulture and hopped a plane to the island of Oahu, Hawaii. When I wasn’t surfing or at a luau I was gaining valuable knowledge about irrigation. After 3 years of island hopping I was desperate to enjoy the good ol’ Minnesota winters again, haha. I returned to Minnesota in 2008 and was employed as an irrigation technician with the Landcare Department at the U of M. I am very thrilled to join the turfgrass team here. I hope that my “spade” of working knowledge is an asset to this brilliant team and I look forward to meeting all of you in the near future.”

So unknown to him, we put our skates on, sans guards of course, because they always got lost during the trudge through the snow, and proceeded upon the shortest route, right across the green. Winter soon changed to spring and the lesson of discipline caught up with me.
Long before Prairie Dog hunting was popular in the Dakota’s, my older brother Rob and I were honing our rifle skills by harvesting the thirteen stripe ground squirrels that inhabited the golf course. In the evening we would “army crawl” on our bellies over the berms and through the fescues with our trusty Sheridan Blue Streak pellet guns. Cautiously we would peek over the hills and It seemed that we actually sight in on our quarry. At first were a head of our time when it we often missed our shots and sent the creatures chirping and came to linear aerification, for racing down their burrows, but covering the sixth green were hundreds and hundreds of slices soon our patience and practice created from the many trips to paid off with a harvest of and from the pond wearing our carnage. guar less skates.

crew in the morning we were sure! Other evening events with brothers Rob and Curt involved the irrigation system. Back in the old days, golf courses used to be watered using large impact irrigation heads capable of shooting a thick stream of water over one hundred feet through the air. The force behind the spray was called pressure. In an effort to cool down on warm nights we would trek out to the fairways and have all sorts of fun with the master blasters. Lesson learned included: 1) liquid propelled under high pressure hurts, especially if said liquid happens to inadvertently blasts a young lad’s private part. 2) Wet grass upon a steep slope is very slippery and one should approach the irrigation head cautiously from the bottom of the hill so
as not to fall into previously mentioned steam of water. 3) Never trust brother Rob when he is calling you over to “look at this cool thing” while he is in control of the direction of the irrigation head. Ah, youthful education! At the age of seven I had my first personal driving experience in a sun recharged electric golf cart. Of ten times the old style electric carts would seemingly run out of juice during the warm afternoons, only to come back to life after setting a bit. Of course it was Curt and my mission to locate these abandoned vehicles and attempt to advance them toward the pro shop. Most of the time they were keyless, but once in a while luck was with us and we had our own autobahn opportunities. It was on one of these outings that I learned you should not trade drivers as the cart is moving down the fairway.
The electric carts we drove were equipped with automatic brakes that locked up the vehicle when the seat is vacated. Fortunately for me I was the driver in this instance and only bruised my chest when I moved off the driver’s seat in an attempt to trade steering position with my brother. Unfortunately for Curt, he was the passenger and was sent flying multiple yards through the air and onto his head. Talk about a face plant! Lesson learned: stay seated when driving a vehicle.

As I grow older I will continue to enjoy my time on the course. There are so many new experiences to witness. And through this education I will try my best to laugh at the fun stuff, learn from the challenges and when I really need a smile I will remember my own youthful attempts at “knees n’ toes and knees n’ toes n palms” at the WBYC.
