1. Water Conservation and Drought Tolerance

 Mississippi State University (MSU) recently completed a 2 year NTEP study on water used in warm season species.  Work by MSU continues on an effort to characterize the influence of the soil microbiome on localized dry spot in golf course greens. 

Dr. Grady Miller investigated the impact of drought on different turfgrass species used NC. He is also currently investigating a novel transition method to convert tall fescue lawns to more drought tolerant warm-season species.

Faculty at LSU conducted research evaluating field elevation using UAV mounted LiDAR to predict better drainage installation for Louisiana. The research was presented at the LTA conference and published and presented at the European conference on precision agriculture. 

Dr. Jespersen is currently advising two Ph.D. students in water related issues. R. Teja is focusing on mechanisms of drought tolerance, while S. Mondal is looking at the genetics underlying salt tolerance.

New UT Hire (Bowling) will focus on irrigation, water quality, and water conservation in her Extension and applied research program.

Dr. Mingying Xiang is co-advising an MS student, Snigdha Arikilla, who is conducting research on water use and the relative drought resistance of bermudagrasses. The study aims to determine the water use rate of various bermudagrass cultivars and experimental selections. The findings of this research were presented at the Southern Region ASHS Meeting, held from February 3 to 5, 2023, in Oklahoma City, OK.

Dr. Mingying Xiang is supervising Binod Pokhrel in a study that compares the relative salinity tolerance of different bermudagrass varieties. This research focuses on analyzing the anatomical structures of these grasses that may contribute to their salinity tolerance.

Dr. Mingying Xiang is guiding Binod Pokhrel in a study that examines the impact of horticultural spray oil on the salinity tolerance of bermudagrasses.

Dr. Shuhao Yu is advising an incoming graduate student to conduct a first generation selfed-pollinated common bermudagrass QTL mapping study to dissect the genetic insight of drought resistance and develop molecular markers that can be used in marker assisted selection in drought resistant bermudagrass improvement.

Dr. Shuhao Yu is co-advising an undergraduate student to screen a first generation selfed-pollination African bermudagrass population under saline water to identify salinity tolerance QTL. The genetic and genomic information from this study can be used in salinity tolerant bermudagrass improvement that can be irrigated using saline water to achieve overall water conservation.

Dr. Shuhao Yu is co-advising a graduate student conducting a genome wide association study to identify QTL associated with drought resistance in common bermudagrass. The QTL identified from this study can reveal genetic insight of the diverse population. Molecular markers will be developed and used in marker assisted selection in drought resistant bermudagrass improvement.

Dr. Charles Fontanier is advising a MS student (Manveer Singh) investigating use of soil moisture sensors to conserve water during establishment of bermudagrass from sprigs.

Dr. Straw developed a free, licensed Golf Course Soil Moisture Mapping Protocol that assists golf course superintendents worldwide in implementing precision irrigation through the creation of soil moisture management zones. The protocol's adoption has potentially saved billions of gallons of irrigation water on golf courses in nearly 30 states, Canada, the United Kingdom, and New Zealand.

Dr. Wherley’s current role in the USDA SCRI project is to determine reference Crop Coefficients, Stress Coefficients, and better understand drought resistance mechanisms of advanced warm-season turf lines from earlier projects. The work is being prepared for publication in Crop Science.

Chandra’s is working on developing drought resistant (USDA-SCRI and TPT-funded) and cold tolerant (USGA-funded) cultivars of St. Augustinegrass and zoysiagrass.  Several advanced hybrids originating from Texas A&M breeding program are in current NTEP trials and in pre-commercialization pipeline.  ‘Lazer’ zoysiagrass (putting greens zoysiagrass) and ‘Innovation’ zoysiagrass (fairway/home-lawn) are the most recent releases from the breeding program. 

Segars, Straw and Chandra have been evaluating zoysiagrasses belonging to different textural classes under different levels of traffic. 

2. Nutrient Management

 Several fertilizer treatments have been evaluated in the grow-in of putting green grasses at MSU.  Work has begun at MSU to identify warm and cool season grasses and blends of grasses for their efficacy as turf under solar panels at solar farms. 

Hired Qiyu Zhou who’s specialty is nutrient modeling and precision turfgrass management. Dr. Grady Miller conducts numerous research projects on nutrient management currently and in the past.

Faculty at LSU completed a grant funded project to evaluate organic fertilizers use in landscapes. Results were presented at the LTA conference, one trade publication was written, and the first of three peer-reviewed publications has been printed. A grant to evaluate the production and processing black soldier fly frass was funded; and initial work is being completed to develop standards for evaluating and processing BSF frass as a fertilizer for various horticulture crops including turfgrass.

Dr. Henry advised a PhD student (Julie Wang) who investigated the impact of fertility on the competitive nature of common lawn weeds with hybrid bermudagrass and centipedegrass in Georgia. (Wang, C.J., G.M. Henry, J.D. McCurdy, and D. Held. 2022.)

Wherley was involved on GCSAA-EIFG funded project to develop late season nitrogen fertilization strategies for bermudagrass fairways in the southern United States.  The project has evaluated application timing and N source effects on N uptake efficiency during the fall and winter months as well as spring green-up. The work is being prepared for publication in Crop Science.

3. Pest Management

 Work continues at MSU on several weed pests of warm and some cool season turfgrasses.  A workflow has been developed to standardize taking digital data from UAV’s and splicing it together for analysis of small plot work.  A study of PRE herbicides use in the grow-in of St. Augustinegrass was used to develop the workflow.  Work continues at MSU on inclusion on identifying forbs that can be included in warm season turfgrass stand that provide forage for pollinators. 

 Many developments in pest management in NC. Dr. Rick Brandenburg and Terri Billeisen reworked annual bluegrass weevil models to more accurate predict development in NC mountains. Dr. Kerns developed best management practices for management of soilborne diseases on golf course putting greens that centered on how much post-application irrigation is required to suppress fungi and nematodes. Dr. Gannon determined how certain herbicides move after application and identified best management practices to limit herbicide movement. Dr. Yelverton has been developing new herbicide rotations and programs for goosegrass and annual bluegrass control.

Dr. Henry advised an undergraduate student (Audrey Young) who investigated the tolerance of carpetgrass to common POST herbicides in the greenhouse and field in Georgia. (Young, A. and G. Henry. 2022.)

Dr. Bahri, in collaboration with Dr. Martinez used next-generation sequencing technologies to uncover the etiology and pathogenicity of Clarireedia spp., the pathogens responsible for dollar spot on turfgrass in Georgia. Key discoveries include: 1) Clarireedia monteithiana (98%) is the main pathogen responsible for the disease in the state of Georgia, followed by Clarireedia jacksonii (2%); 2) a new species, Clarireedia aff. paspali, originally identified in Hawaii in 2019 also contributes to dollar spot disease in the U.S.; 3) Genetic variability was revealed within 201 Clarireedia monteithiana isolates collected across 136 counties in Georgia; 4) 17 genes were potentially involved in the pathogenicity of Clarireedia spp., including six genes (nox1, nox2, pka1, smk3, pph1, gpd) involved in appressorium formation, oxalic acid production, mitogen-activated protein kinase (MAPK) cascade and hyphal growth.

Dr. Bahri, in collaboration with Dr. Martinez (UGA Griffin) and Dr. Oliver (UGA Tifton) investigated the fungicide sensitivity of 79 isolates of Clarireedia spp. collection from Georgia against four groups of fungicides. The results showed that 77, 27, 53, 47 isolates were sensitive to thiophanate‐methyl (benzimidazole), propiconazole (dimethyl inhibitor), boscalid (succinate dehydrogenase inhibitors), and azoxystrobin (strobilurins). One isolate from Spalding county showed resistance to all four fungicide groups.

In addition, Dr. Martinez, in collaboration with Dr. Bahri, developed molecular tools for dollar spot detection including 1) co-dominant cleaved amplified polymorphic sequences (CAPS) that differentiates between C. jacksonii and C. monteithiana, further validated using direct PCR to speed up the diagnosis process; and 2) An assimilating probe-based loop-mediated amplification (LAMP) assay that provides specific detection of C. monteithiana and C. jacksonii to be used in the field for on-site, point of care pathogen diagnosis.

By using a prototype robot that delivers UV-c radiation, Dr. Bahri and collaborators (Dr. Martinez, Dr. Raymer, Dr. Jespersen, Dr. Waltz) are investigating the efficiency of UV-c light in controlling dollar spot development in vitro, as well as in greenhouse and field trials. A decrease in the mycelial growth by 10.3 and 12.2% was observed with 1 and 5 min of daily treatment, respectively. The results also showed that the UV-c light treatment does not kill the pathogen even after one month of daily application.  In the field, daily UV-c light treatment reduced the number of dollar spot infection centers by 67% and the overall dollar spot incidence by 63% when compared with non-treated controls.

Dr. Bahri and Dr. Martinez’s research is also focused on exploring the potential benefits of nanobubble oxygenated water in turfgrass systems. In preliminary in vitro trials, application of water enriched with oxygen nanobubbles resulted in a reduction of mycelial growth of Clarireedia by 12% on artificial media and mycelial mass by 8%. Oxygen nanobubbles also suppressed mycelial growth of Rhizoctonia solani by 9% in vitro. In addition, greenhouse trials showed a significant reduction of dollar spot on seashore paspalum after 7-day of oxygenated-nanobubble applications but no effect of oxygenated-nanobubbles on Rhizoctonia solani infection on zoysiagrass.

Dr. Bahri, in collaboration with Dr. Martinez, investigated the potential use of biofungicides to reduce rhizoctonia large patch and dollar spot in turfgrass. In vitro results showed that the fungicides Xzemplar (fluxapyroxad), Medallion (mixture fludioxonil, propane-1,2-diol, triethylamine), Velista (penthiopyrad), and Banner Maxx (propiconazole) reduced R. solani mycelial growth by 77-100% compared to the control. Interestingly, Stargus and Rhapsody induced a significant reduction in the growth of R. solani (79-92%) and C. monteithiana (100%) compared to the control group. In addition, the stand-alone application of biofungicide Rhapsody (B. subtilis QST713) every 7 days was the most effective and equally efficacious as Banner Maxx (propiconazole), suppressing dollar spot severity up to 34 and 75% and AUDCP up to 43 and 75% in growth chamber and field experiments, respectively while resulting in acceptable turf quality (>7.0) in the field.  Similarly, Rhapsody (B. subtilis QST713) applied every 7 days on large patch infected zoysiagrass ‘El Toro’ was the most efficacious, reducing disease severity by 72 and 76% in the growth chamber and field experiments, respectively. Overall, the findings showed that B. subtilis QST713 holds promise to complement synthetic fungicides for managing dollar spot and Rhizoctonia large patch of warm season grasses in Georgia.

Dr. Joseph’s research and extension program focus on turfgrass and ornamental entomology. In the past year, he had three graduate students working on the turfgrass program. Two students graduated with doctoral and master’s degrees. One student was involved in developing management tactics for Rhodesgrass mealybug in putting green. Another student studied how the various stages of sod development shaped the arthropod communities and the nontarget effects of commonly used insecticides. The third student is studying the role of centipedegrass on pollinators. In addition, Dr. Joseph is involved in many management projects involving pests, such as mole crickets, southern chinch bug, white grubs, and billbugs.

7 weed control reports were developed and sent to the Florida Turfgrass Industry.

Dr. Charles Fontanier advised an MS student (Ashton Franks) who investigated nitrogen and plant growth regulator rate effects on dollar spot disease incidence in creeping bentgrass.

Texas A&M Turf Pathologist Dr. Young-Ki Jo has conducted USGA-funded research to develop a diagnostic protocol for Gaeumannomyces species associated with take-all root rot in bermudagrass and to remediate economic losses from the disease in bermudagrass putting greens.  He published a new article about take-all root rot entitled ‘Uncovering the mystery behind turf loss this spring’ through AgriLife Extension.

Texas A&M faculty Bagavathiannan and Bowling are wrapping up a 4-year USDA-NIFA funded Specialty Crops Research initiative focused on addressing the herbicide resistance epidemic in annual bluegrass in managed turfgrass systems. Andrew Osburn (PhD student) is heavily involved in this project on 2 sub-objectives and assisting with several others.

Texas A&M faculty Chandra, Wherley, Grubbs, and Segars continued to participate on a third multi-year (4-yr) USDA-NIFA funded Specialty Crops Research Initiative project involving collaboration among faculty from Texas A&M AgriLife Research, Oklahoma State Univ., Univ. of Florida, Univ. of Georgia, N.C. State University, and UC Riverside.  Goal of the current project is to advance drought and salinity tolerant turfgrass cultivars developed during the earlier projects (2011-2019) and determine reference ET-based water requirements, wilt-based minimal water requirements, and drought resistance mechanisms. This multidisciplinary project involves breeders, physiologists, extension, and economists.  These projects have garnered over $16 million in funding and resulted in co-authorship on seven peer-reviewed publications (4 published and 3 in prep).  More importantly, six cultivars possessing superior drought and salinity tolerance have been released from the program.  The first of these cultivar releases, ‘TifTuf’ bermudagrass, uses 38% less water than ‘Tifway’, the most widely utilized bermudagrass cultivar around the world.  Since this release, ‘TamStar’ St. Augustinegrass and ‘Tahoma 31’ bermudagrass have also been released from the program. These two drought tolerant grasses are increasing in production acres and licensees across the U.S. The most recent drought-tolerant release, ‘CitraBlue’ St. Augustinegrass, is under initial expansion with producers, and two zoysiagrass releases are still being evaluated by producers to make decisions regarding commercialization.

5. Developing and Conduction Educational, Extension, and Outreach Programs Summarizing and Promoting Transfer of the previous 4 areas.

Drs. McCurdy and Stewart (MSU) presented at various conferences including the Deep South Turf Expo, Southern Weed Science Society, Weed Science Society of American and American Society of Agronomy.  Topics ranged from soil microbiome, soil health, artificial turf, pollinator habitat, the grow-in of several grass species, and nutrient management to incorporation of technologies from LiDAR to a novel seed coating.

The NCSU Turfgrass Center supported 15 graduate students and the funding resulted in 82 publications on various topics in turfgrass science. Over 150 presentations were given to disseminate the information generated from the research supported through the Center funds. Each year NCSU hosts a field day at the Turfgrass Research and Education Facility at Lake Wheeler Road which draws between 700 and 900 attendees and is the single biggest field day in the College of Agriculture and Life Sciences at NC State University.

There were several presentations from LSU graduate students and Dr. Beasley at various conferences including LTA, ECPA, LSU Agricultural Center Annual Conference, and ASHS on topics ranging from nutrient management to incorporation of technologies from LiDAR to a novel seed coating. Efforts in nutrient management have resulted in three BMP publications for the golf industries in Louisiana and Mississippi through a joint effort with MSU faculty. This information provides superintendents as well as athletic field managers methods to improve nutrient management, water quality, and irrigation application. 

UT Turfgrass team members have established themselves as highly sought-after educators requested to speak to audiences across the globe. Drs. Brosnan, Sorochan, and Horvath delivered 155 presentations during this time frame to audiences at regional, national, and international meetings from 2020-2022. These Extension efforts facilitated growth of turfgrass teaching and research programs as well. For example, undergraduate students in the turfgrass program have been placed at internships at elite turfgrass venues from stadiums in the English Premier League to golf courses such as Augusta National Golf Club. The UT Turfgrass Team has been selected to lead all field research efforts in advance of the 2026 FIFA World Cup.
