From the President

Calendar of Events THURSDAY, JANUARY 21, 2021

I am Optimistic I

sincerely hope this letter finds everyone safe and healthy. 2020 has been a challenging year and is now behind us. As I look forward to 2021, I am optimistic that this year is going to bring some relief. It will be wonderful to be able to once again shake the hand of a friend, and have a sit down meal with family and friends without worrying. The turf industry, as a whole, has weathered the Pandemic fairly well. If you have been one of the fortunate ones whose life has not been disrupted, I want to encourage you to look around. You will see many people in need of help. The green spaces that we as turf professionals provide have been a much needed respite for many who have had to shelter in place. I would, also, encourage you to see other ways that you may be able to help during this difficult time. This will be my last letter as President of TCNC. It has been my honor to serve this great organization, and to work with the other board members. Kevin Herman will be your next President. He has been involved with TCNC for many years, and has been a leader in this industry during his career. As we transition, I am confident that TCNC will continue to grow under Kevin’s leadership, and that TCNC will continue to support the turf industry and our membership. Be Well,

ALTERNATIVE WEED CONTROL IN TURFGRASS By D.E. Carroll & J.T. Brosnan

certain regions of the United States and Canada, legislation has severely restricted traditional synthetic herbicide use in residential and commercial landscapes. Specifically, residential use of synthetic pesticides deemed “cosmetic use” in the Ontario Province, Canada, has been banned. Other aspects of the turfgrass industry such as sports and golf are able to receive exemptions through government approval, stated reduction goals, integrated pest management certification, and increased transparency requiring reporting and in-person meetings to discuss pesticide application. (Ontario Regulation, 2018). Similarly, in Montgomery County, Maryland, the use of synthetic pesticides perceived for use cosmetically is banned. Only natural, non-synthetic herbicides listed by the Organic Materials Review Institute (OMRI) may be used for this purpose (County Council for Montgomery County, Maryland, 2019). Many local governments, such as the city of New York, banned glyphosate use on public land such as school districts, parks and in municipalities, except for maintenance of invasive plants in native area. (The New York City Council, 2019). In the United States, many active ingredients in organic pesticides are considered minimum risk, categorized as section 25b products, and are exempt from the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) registration process. Products must meet six criteria for inclusion in this category. Because labeling in this category is typically not federally regulated, labeling of non-synthetic herbicides is not consistent and may include wording such as “organic” or “natural”, despite these products not undergoing typical organic product registration. Although not required by federal law, independent agencies perform organic standard research to determine which products receive organic seals on labeling (Figure 1). Additionally, individual states may still require a registration process for minimum risk products and may limit herbicide use in some areas to only products listed by independent testing agencies. An example of a natural product research agency that maintains a list of products compliant with internal organic standards is OMRI. OMRI is a non-profit organization, and thus not considered a regulatory agency. Conversely, the Environmental Protection Agency is considered a regulatory agency and although not federally required, also tests natural products and lists those meeting organic criteria. Active ingredients on these lists include chelated iron, acetic acid, corn gluten meal, and a variety of soaps and oils. Chelated iron, also referred to as Iron HEDTA, is concentrated iron formulated for increased uptake in broadleaved weeds versus grasses. Once inside the plant, the iron is oxidized and causes necrosis (Charbonneau, 2010).

Acetic acid, which is concentrated in household vinegar used for cooking at 5%, is generally concentrated in horticultural vinegar at 20 to 40%. Horticultural vinegar applications can kill weeds by removing the waxy cuticle found on leaves, thus drying out the plant. Citrus oil and soaps such as pelargonic acid or ammoniated fatty acid work in similar fashion by stripping the leaf cuticle to facilitate water loss. Unlike many synthetic herbicides, products with these active ingredients are generally fast acting and results may be observed within a few hours of application (Figure 2). Products containing these active ingredients are widely available to the public and can be purchased at most big box retail stores and online (Figure 3). Due to the lack of regulation in labeling, many manufacturers produce products of differing trade names that have similar active ingredients included at variable concentrations. For example, horticultural vinegar is available as Green Gobbler concentrated at 20, 30, or 40% acetic acid; Eco Garden Pro (8% acetic acid + 5% sodium chloride); or as WeedPharm (20% acetic acid) among others. A common misconception is that products labeled as “organic” are non-toxic. This is false. Similar to synthetic pesticides, product labels contain the signal words caution, warning, or danger to alert applicators to toxicity. “Caution” labeling indicates the lowest level of toxicity to humans followed by “Warning” meaning moderately toxic and “Danger” denoting high toxicity. An example of organic herbicide toxicity labeling is horticultural vinegar labeled with a “Danger” distinction because the product is a strong irritant and needs to be used with care. It is critically important that end-users read and follow label instructions for both conventional and alternative herbicides before application. Most of these alternative weed control products are nonselective and are therefore injurious to desirable turfgrass (Figure 2). To mitigate injury concerns, these alternative options should be used to spot-treat individual weeds rather than being applied via broadcast sprays. Research conducted at the Pennsylvania State University (University Park, PA) assessed the efficacy of AXXE (40% ammonium nanonate), horticultural vinegar (30% acetic acid), Fiesta (26.2% Iron HEDTA), Avenger (70% d-limone citrus oil), and A.D.I.O.S. (11.9% sodium chloride) for control of dandelion (Taraxacum officinale G.H. Weber ex Wiggers) and white clover (Trifolium repens L.) in perennial ryegrass (Lolium perenne L.). Herbicide treatments were applied in late July with sequential applications made on two or four week intervals. Three applications of Fiesta applied at 25.2 fl oz/1,000 ft2 every four weeks controlled clover and dandelion within six days of initial application through mid-October.

While not considered injurious to the turfgrass sward, increased iron uptake in the desired perennial ryegrass stand resulted in grey discoloration (Figure 4). Other natural, non-synthetic herbicide treatments including AXXE (15% v/v) and horticultural vinegar (50% v/v) provided

some control of both weed populations compared to an untreated check, although both were injurious to turfgrass (Figure 5). Treatments of A.D.I.O.S. (50% v/v) or Avenger (14% v/v) did not control dandelion or clover and were not injurious to desired turfgrass.

Research conducted at the University of Tennessee (Knoxville, TN) in summer 2019 found similar results. A trial initiated in late July assessed the efficacy of eight alternative herbicides (Fiesta, Avenger, Burnout, horticultural vinegar, A.D.I.O.S., Biosafe, Natria, and WeedBeater Fe) for control of white clover. Two weeks after treatment, several alternative products controlled white clover similar to a single application of Trimec Classic (2,4-D, MCPP, and dicamba) at 3 pt/A; these alternative treatments included single applications of Fiesta applied at 12.6, 25.2, or 50 fl oz/1,000 ft2; horticultural vinegar (30% acetic acid; 50% v/v); and Avenger (70% d-limone citrus oil; 20% v/v). The desired fine fescue (Festuca spp.) turfgrass stand was discolored following Fiesta treatment and injured by horticultural vinegar and Avenger. Treatments of Natria (3.7% ammoniated soap of fatty acid; 20% v/v), Biosafe (40% ammonium nanonate;15% v/v), WeedBeater Fe (1.5% Iron HEDTA; 100% v/v) and A.D.I.O.S (11.86% sodium chloride; 33% v/v) did not control white clover. Burnout (24% citric acid + 8% clove oil; 6% v/v) controlled clover ~ 50% compared to a non-treated check. A second trial was conducted in February 2020 at the University of Tennessee to assess efficacy of alternative weed control products for control of winter annual broadleaf weeds in dormant bermudagrass (Cynodon spp.). Eleven days after treatment, Fiesta applied at 12.6, 25.2 or 50 fl oz/1,000 ft2; AXXE (15% v/v); horticultural vinegar (50% v/v); and Natria (20% v/v) controlled broadleaved weeds such as hairy bittercress (Cardamine hirsuta), henbit (Lamium amplexicaule), mouse-ear chickweed (Cerastium vulgatum), and corn speedwell (Veronica arvensis) ~ 50%. Thirtythree days after initial treatment, the end of the study, Fiesta applied at 25.2 or 50 fl oz/ 1,000 ft2 with a three-week sequential application controlled these broadleaf weeds 60 to 80%, similar to Roundup Pro at 16 fl oz /A and Cheetah Pro at 82 fl oz/A. At the end of the study, AXXE, horticultural vinegar, and Natria, treated sequentially three weeks after initial application, controlled these broadleaved weeds ~ 25%. The low control provided by these products at the end of the study compared to the 50% control observed 11 days after treatment indicates that sequential applications should be made every two weeks to obtain the greatest weed control.

Results of these research projects show that alternative weed control products can reduce weed populations compared to non-treated turfgrass, although outside of Fiesta, they are generally not as effective as traditional synthetic herbicides. Alternative products are not translocated throughout plant tissue, which often results in regrowth of treated weeds. Therefore, sequential applications will be required for sustained weed control, which can be costly. For example, an application of Fiesta at 50 fl oz/1,000 ft2 is approximately $25.40 per 1,000 ft2, compared to $0.76 per 1,000 ft2 for an application of 2,4-D + MCPP + dicamba at 4 pt/A. Changing legislation in certain areas of the United States and Canada may put pressure on synthetic pesticide use in turfgrass. Homeowners and turfgrass managers should be aware that while natural herbicides may be an effective tool compared to not using any weed control product, they are not an equivalent replacement to synthetic herbicides. In scenarios where alternative weed control products are required or preferred, they can be used to control select weed species via spot treatments applied sequentially. Products containing high concentrations of chelated iron, such as Fiesta, or acetic acid can be used for broadleaf control when applied as sequential spot treatments. However, these applications can cause undesirable injury or discoloration to turfgrass. More research is needed to better understand alternative methods of controlling weeds in maintained turfgrass. Investigations pertaining to effects of environmental or meteorological factors on efficacy of these products are warranted. The authors would like to thank Dr. Frank Rossi, Associate Professor and Extension Turfgrass Specialist at Cornell University, and Vickie Wallace, University of Connecticut Extension Educator and Program Director of UConnâ&#x20AC;&#x2122;s Sustainable Turf and Landscape Program, for their assistance in developing this article.

Grady Miller: Helping Turfgrass Managers on the

ROUTE TO RECOVERY By Jennifer Howard, Communications Specialist, NCSU

arch’s COVID-19 shut-down caught everyone off guard. There was little time to prepare for closings and no one knew how long they would last. Many turfgrass managers and municipal employees were suddenly told to go home. That’s when the emails and phone calls to Jimmy Simpson began to accumulate. As the current President of the Sports Turf Managers Association (STMA), he heard the concerns and fears of the unknown which members expressed. In good sports leadership fashion, Simpson called in a team, including NC State’s turfgrass management expert Grady Miller. C O NTI NU E D Dr. Grady Miller is hands-on when working to help turfgrass managers affected by COVID restrictions.

“When building out the task group I tried to try to hit as many areas of our industry as possible. I requested Dr. Miller’s help because he is a strong advocate for natural grass and for sports turf managers throughout the world. I knew he would bring that advocacy to the table, Simpson said.

The Go-To in Turfgrass Management This wasn’t Miller’s first call to consult on turfgrass management. He was part of a U.S. envoy to evaluate the 2007 Olympic turfgrass venues in Beijing and is a past advisor to many college and pro sports teams including the Chicago Bears and the Italian Soccer Premier League. “I was honored to serve on the STMA taskforce. We asked ourselves ‘how we can help [sports field managers] get through this shut-down?’, knowing there would certainly be agronomic problems, but also psychological concerns,” Miller said. He and seven other volunteers held weekly Zoom meetings to identify specific member pain points and form a plan of action.

Volunteering for Healing Throughout the 2020 summer, NC State University offered employees time off for COVID-related volunteer work. While employees contributed to communities in various ways, Grady Miller had a specific calling. “My role was to write and organize literature. A lot of these turf managers were losing budgets, workforce, and the ability to maintain their facilities. [Serving them] wasn’t just about agronomics, but about supporting people who felt at a loss,” Miller said. The committee worked through the summer creating several digital publications, Healing Through Sports, Route to Recovery, and the STMA Renovation Guide. They also provided members with an inspirational video, a letter to government leaders requesting field managers to be designated as essential employees, and a series of town-hall-style virtual meetings. “STMA has had tremendous usage of our Route to Recovery guides. Members have told us these digital guides helped them communicate with their employers on best practices for their fields during the pandemic. They are solid additions to our educational resource library,” Kim Heck, STMA CEO said. “[Dr. Miller’s] expertise, along with his fellow task group members, helped us provide actionable information to our membership to ensure the safety and playability of natural grass sports fields.”

Documenting Turfgrass Recovery For Grady Miller, the job didn’t end as restrictions eased. He brought the work home. “I realized that we had never documented the techniques to get an abandoned field in shape. We really didn’t know how quickly it could be done. So I told [graduate student] Raymond McCauley to just stop mowing a large area at our turfgrass field laboratory. We needed to test the recovery methodology.”

Dr. Miller working with graduate students on precision seeding of turfgrass

Starting in March, the team allowed several university turfgrass research plots to grow unattended and untreated, just as those in the public sphere. The grass, and the weeds, shot up. “I tried not to look at it,” Miller sheepishly admitted. Then in late July, his team resumed treatments and mowing as normal. “The change wasn’t overnight - the Panthers couldn’t just play on it the next day. But we’ve proved that with specific treatments, you can take a field that looked like trash and turn it into something fit for a world-class facility. It’s a process, but our techniques work.”

Miller is pleased that graduate students had the opportunity to get experience outside their normal projects. He plans to continue the turf recovery testing to validate his findings. Results will be shared in future publications and field days, but his volunteerism on STMA’s volunteer task force produced unmeasurable results – pride in serving members. “The organization recognized its members’ needs and didn’t constrain our response. We just wanted to help them get through this experience and be ready for whatever came next.”
