PRESIDENT’S MESSAGE
VOLUNTEER AND PARTICIPATE! “Volunteering is the ultimate exercise in democracy. You vote in elections once a year, but when you volunteer, you vote every day about the kind of community you want to live in.” –Author Unknown thought this is a very pertinent quote for our times. As this past presidential election proved that every vote counts, so will your efforts count when you volunteer at the local, state, national or even trade-association level. My term as Maryland Turfgrass Council president is about to end. I definitely grew into this position after first thinking I could not adequately handle the responsibilities and challenges. I’m sure the first meetings I presided over left a lot to be desired. With that, I would like to thank all of the volunteers in the turfgrass community at the MTC. Among them are the members of the MTC board of directors, as they made my job more manageable. As a group, we grew the MTC membership, increased member benefits and worked on additional educational opportunities. I would also like to thank the sponsors and advertisers that supported and continue to support the Maryland Turfgrass Council’s mission. Next in line to volunteer his time and expertise as MTC president is Jamie Roell, who works at Anne Arundel County Parks and Rec. Jamie has been the MTC vice president for a few years and will move up to president if you elect him to that position at our January Annual Meeting during M-A-T-E. The MTC is in great hands with Jamie at the helm and will continue to move in a positive direction for its membership and supporters. Make an effort to say hello at the next Mid-Atlantic Turfgrass Expo (M-A-T-E) conference and tradeshow. Speaking of M-A-T-E, I hope you make plans to attend the next event on January 30 – February 2, 2017, in Fredericksburg, VA. University of MD and VA Tech’s Drs. Tom Turner and Mike Goatley started planning early for this event. Their hard work has paid off again with securing some top-notch speakers and great turf-management topics. Last year’s M-A-T-E conference and tradeshow generated more than $20,000 toward turf research for those universities. This year’s proceeds will again go to the university turfgrass-research programs. Help us surpass last year’s number… so please, get the word out. I hope to see you there! Go out and volunteer for the kind of community you want to live in, and promote the benefits of turfgrass!
I
Thanks!

FROM THE MTC EXECUTIVE DIRECTOR
Starting Anew In • • • • •
•
the turfgrass profession, we often think of winter as a “period of rest,” but is it really? Winter in my opinion is really for “starting anew!” We use winter to purchase, repair and mend equipment to start a new season. We use winter to purchase or order seed, fertilizer, pesticides and other supplies to get the best price. We use winter to prepare new and additional marketing to increase our business. We use winter to train our employees with current and new knowledge to do the job better and safer. We use winter to take some time to enjoy family and friends over Halloween, Thanksgiving, Christmas, New Year’s and other special holidays in our lives to rejuvenate our bodies and spirits. We use winter to register to attend the Annual M-A-T-E Conference in Fredericksburg to increase our professional networking, to expand our agronomic knowledge, to renew our pesticides and fertilizer applicator certifications and to partake in what is NEW.
What is new? We are always looking to improve the M-A-T-E program to provide you with what you’ve been requesting. After all, this is “your” conference. This year, we are trying a couple classes on Tuesday in Spanish. Dr. Jorge Ribas, the president and CEO of the Mid-Atlantic Hispanic Chamber of Commerce will provide classes on the basic introduction to turfgrass and also an understanding of the pesticide and fertilizer applicator requirements. This was brought to us as a need, and we have responded. Early interest appears to indicate we will be adding additional classes in Spanish next year. Additionally, there are four days of new informative classes and information with the keynote speaker, Dr. Dan Potter from Kentucky, delivering a key note talk on “Bee Decline, Pesticides and Politics: Challenges and Opportunities for the Green Industry.” Pesticide recertification will also be offered on multiple days this year. The expanded tradeshow has lots of new and returning vendors, but a few spaces are still available. Would YOU like to be an exhibitor? Go to www.turfconference.org to download the vendor forms and/or if you prefer to become a sponsor. Get your registration done today — YOU don’t want to miss this, and remember that all profits go directly to the University of Maryland and Virginia Tech for local turfgrass research to help us all evolve. Contact me for an application or assistance at ExecDir@MDTurfCouncil.com or 410-745-9643. See you in Fredericksburg!

COVER STORY
A REVIEW OF
FOR THE MID-ATLANTIC SUPERINTENDENT By Cody Beckley, Graduate Student, and Joseph Roberts, Ph.D., Assistant Professor, Turfgrass Pathology, University of Maryland
Few
turfgrass diseases impact the quality of annual bluegrass putting greens more rapidly than anthracnose can. If left unchecked, this disease is capable of quickly thinning out turf stands and leaving pitted, scarred putting surfaces in its wake. Mid-Atlantic managers of annual bluegrass turf are likely to have a difficult time dealing with this stress-induced disease, due to the often ever-present summer heat and humidity of the region. Fortunately, in the last decade, university research has provided
16
MTC TURF NEWS
new and updated best management practices (BMPs), including validation of new chemical control options. To assist turfgrass managers with their off-season preparations, this article will provide an overview of the pathogen, discuss critical control periods of the disease and review BMPs for optimum control. Winter months offer an excellent opportunity to plan ahead, as some of the recommendations may require a significant investment of resources, along with consistent implementation, to be most effective.
Pathogen, host, occurrence and symptoms Anthracnose is caused by the fungus Colletotrichum cereale, which can overwinter in turf or soil before infecting its grass host. While at least 13 warm- and cool-season turfgrasses are susceptible to anthracnose, annual bluegrass and creeping bentgrass are the most vulnerable. Disease distribution often occurs wherever these turf types are grown at putting green height (below 0.125"), although anthracnose can occur on higher cut turf as well.
these structures under the microscope will reveal numerous spores capable of spreading infection to neighboring plants (Photo 4).
Cultural controls Cultural practices that mitigate traditional environmental stress factors can limit the incidence and severity of anthracnose infection. Still, it is important to consider the following recommendations when planning your management strategies.
Fertility Turfgrass should be appropriately fertilized throughout the year as dictated by soil-test recommendations and weather patterns. Granular applications of N (1 to 2 lbs./1,000 ft2) have been shown to be more effective at reducing anthracnose on annual bluegrass greens when applied in the spring vs. the fall. Regarding foliar applications, research has shown that starting frequent applications of low-rate soluble-N fertilization (0.1 lb./1,000 ft2/ week) earlier in the growing season reduced anthracnose severity up to 24% compared to applying the same rate every 28 days. They also found that slight increases in N rate (0.2 lb./1,000 ft2/week) on areas with historic problems can aid in disease suppression.
Irrigation
Anthracnose disease can manifest as a foliar blight or basal rot infection. Foliar blight anthracnose typically occurs in the summer, when temperatures are at or above 78°F along with periods of extended leaf wetness. Symptoms include small yellow- to orange-colored spots on turf (Photo 1), and close inspection of infected tissue can show small lesions. Though foliar blight symptoms may be the first indication that the disease is present, basal rot anthracnose may be the first to develop. Basal rot anthracnose can occur in the spring, summer or fall when temperatures range from 58°F
to 70°F, also combined with periods of extended leaf wetness. Symptoms of basal rot appear as a patchy yellowing of upper-leaf tissue, but the as the name implies, the bases of infected plants exhibit dark discoloration and rotting of leaf sheaths, crowns and stolons (Photo 2). Continued disease progression can result in similar symptoms as described with foliar blight, ultimately leading to large, irregular patches of discolored, thin turfgrass (Photo 3). Large amounts of black, spiked fruiting structures (acervuli) can be observed with either foliar blight or basal rot infection. Examination of
The stress a plant experiences from frequent wilting or prolonged saturation greatly increases vulnerability to anthracnose. Drought stress has been shown to be especially operative in regards to anthracnose severity on annual bluegrass. You should irrigate to promote growth and to avoid prolonged wet or dry periods. Previous research has shown 80% ET replacement to be ideal. When possible, use a moisture meter to guide your irrigation scheduling and handwater to correct deficiencies.
Topdressing and aerification Well-draining, non-compacted soil profiles created by regular topdressing and aerification practices favor turfgrass that resists anthracnose disease. A multiyear study at Rutgers showed that weekly or bi-weekly sand topdressing reduced the severity of anthracnose on annual blue-

grass putting greens. The sand build-up provided a protective layer over crown tissue and firmed the putting surface for mowers and foot traffic. Brushing the sand in after application had no effect on anthracnose severity, contrary to popular belief that the wounding from brushing sand into the profile would increase disease. If frequent applications are not achievable, heavier spring topdressings were shown to be most effective for disease reduction. For soil profiles that require amending beyond regular topdressing, yearly aerification and periodic solid-tine venting will improve drainage and increase oxygen availability to roots during stressful environmental conditions.
Mowing and rolling Cutting height has been shown to have a significant influence on anthracnose severity on greens-height turfgrass, more

so than any other part of a mowing and rolling regime. Excessively low mowing heights (i.e., below 0.125") have been implicated in anthracnose outbreaks. Not only does low mowing leave plants with less photosynthetic leaf tissue, but also it can result in scalping and damage to crown tissue during saturated conditions. Standard mowing and rolling frequency (daily single or double cut, daily lightweight roll) has no effect on disease incidence. In the event of an outbreak, incremental increases in mowing height can offset infection and speed recovery. Switching to solid rollers on mowing equipment may also reduce stress and disease progression. Mowing and rolling frequency can be maintained or increased to retain adequate green speed at higher heights of cut. Finally, ensure that all mowing equipment is cleanly cutting leaf tissue. Mower reels and bedknives should be checked routinely to ensure that turfgrass is cut and not torn.
Environment Stress brought on by sub-optimal growing conditions predisposes turfgrass to anthracnose infection. Ensure that all turfgrass receives the year-round, maximum exposure to sunlight and air movement as is possible. Prune or remove trees and shrubs that shade greens or hinder air movement across the turfgrass canopy. Fans can also be utilized to increase air circulation in pocketed areas. In areas with historic disease pressure, consider implementing changes in mowing height and fan use when daytime highs reach and exceed 85°F and nighttime lows don’t drop below 65°F. Make any other adjustments in response to changes in environmental conditions, not just in response to seeing the disease. Ultimately, all cultural practices are most effective at minimizing the incidence of anthracnose infection when used proactively.
Chemical controls When cultural controls are not sufficient to fend off anthracnose, many fungicides

to this disease is greatly amplified when plant health is compromised by nutrient and water deficiencies, prolonged stressful environmental conditions or mechanical injury to the plant. For managing historically problematic areas, consider modifying your cultural practices well in advance of environmental stress periods or the appearance of the disease. Ultimately, you should plan your management strategies early in the year and commit to consistent implementation of BMPs. Fungicides are also very effective tools to control anthracnose and should be used in a responsible manner to minimize resistance issues. If you have any other questions or concerns regarding the disease, contact the University of Maryland Turfgrass Research Program. We’re happy to assist you any way we can.

are available for use in controlling the disease. Multiple chemical classes have historically provided control on nonresistant strains of the disease, including benzimidazoles (thiophanate-methyl), demethylation inhibitors (metconazole, propiconazole, tebuconazole and triticonazole), dicarboximides (iprodione), nitriles (chlorothalonil), phosphonates (aluminum-tris), polyoxin (polyoxin-D) and strobilurins (azoxystrobin, trifloxystrobin). In addition to these classes, newer carboxamides (penthiopyrad) and even new use of an older aromatic hydrocarbon (pentachloronitrobenzene) have also shown good control of the disease. When considering chemical controls, preventative fungicide applications are
most effective in anthracnose management. Apply according to label directions when weather conditions are favorable for disease development, in areas where anthracnose is a common problem. Colletotrichum cereale has demonstrated resistance to fungicides in the past, so avoiding consecutive applications of the same fungicide chemistry or tank-mixing multiple chemical classes will aid in minimizing fungicide-resistance development.
Summary It is often said that anthracnose is considered a secondary stress-related disease; therefore, maintaining a healthy plant is your first and best defense against any outbreaks. Turfgrass susceptibility

The Outdoor Power Equipment Institute (OPEI) is offering tips for safe and correct use of snow blowers. “Your indispensable winter friend, the snow blower is ready to be powered up, and it’s important to keep safety in mind,” says OPEI president and CEO Kris Kiser. “Be sure to prepare and consider the following tips before you use your equipment.”
Prepare before it snows. Review your owner’s manual, and check your equipment. Check your owner’s manual for safe handling procedures from your manufacturer. If you forgot to drain the fuel last winter before storing your snow blower, drain the tank now. Adjust any cables. Check the auger (the snow blower should always be completely powered off when you are checking the equipment). Know how to operate the controls. You should be able to shut off your equipment quickly.
Prepare your fuel, and handle it properly. It’s important to have the right fuel on hand for your snow blower — movement and fuel availability may be limited during a snowstorm. Be sure to use the correct fuel, as recommended by your equipment’s manufacturer (for more information on fueling properly see www.lookbefore youpump.com). Fill up the fuel tank

outside before you start the engine and while the engine is cold. Never add fuel to a running or hot engine.
Be sure to clean the area you intend to clear with your equipment. Snow can sometimes hide objects that if run over by a snow blower, may harm the machine or people. Doormats, hoses, balls, toys, boards, wires and other debris should be removed from the areas you intend to clear.
Dress appropriately. Wear safety glasses and footwear that can handle slippery surfaces.
Operate your equipment safely. KEY SAFETY TIP: Never put your hands inside the auger or chute. Use a clean-out tool (or stick) to unclog snow or debris from your snow blower. Your hands should never go inside the auger or chute. Make sure the snow blower is in the off position before addressing any clogs.
Turn OFF your snow blower if you need to clear a clog. If you need to remove debris or unclog snow, always turn off your snow blower first. Wait for all moving parts to come to a complete stop before clearing any clogs or debris.
Only use your snow blower in visible conditions. Never operate the snow blower without
good visibility or light.
Aim your snow blower with care. Never throw snow toward people or cars. Do not allow anyone to stand in front of your snow blower. Keep children or pets away from your snow blower when it is operating.
Use extreme caution on slopes and hills. Use caution when changing directions on slopes. Do not attempt to clear steep slopes.
Know where your cord is. If you have an electric-powered snow blower, be aware of where the power cord is at all times. Avoid tripping. Do not run over the power cord. More safety tips and information are available at www.opei.org.

MTC TURF NEWS
the morning of Wednesday, September 28, the rain falling and lightning flashing in the sky above had me pacing around Queenstown Harbor Golf Course’s Pavilion in a panic that all the work over the last few months would wash out this year’s Maryland Turfgrass Council annual golf tournament. Initially named The Angie Cammarota Golf Tournament for Turfgrass Research, the golf tournament raises funds to help support turfgrass research projects at the University of Maryland. Despite the rain, the golf tournament went on very nicely. While enjoying donuts, bagels and coffee, Dr. Joseph Roberts talked with attendees about updates in his research at the University as well as problems he has seen throughout the year. After the rain lightened up, a modified round of golf was played in a best-ball format, with prizes going for Closest to The Pin, Long Drive and First and Second Place teams. We ended with an outstanding Crab Feast and dinner while we gave out awards to winners, held a 50/50 drawing and raffled off a few prizes. Congratulations were given to Ben Ellis, Zac Ellis, Lee Ellis and Mike Butler as the winning team. Dave and Nick Cammarota awarded the team with the inaugural Cammarota trophy (graciously donated by Genesis Turfgrass) in honor of former MTC member, past MTC president and father, Angie Cammarota. Big thanks to all of our sponsors, donators and participants. The University of Maryland Golf Tournament for Turfgrass Research Hosted by the Maryland Turfgrass Council raised nearly $3,000! A thank you goes out to the maintenance department at Queenstown Harbor Golf Course and everyone who helped to make this day educational, fun and memorable. We look forward to seeing everyone at our next golf tournament scheduled for September 27, 2017. •
