Highlights from the 31st Annual South Florida Turfgrass Field Day and Expo

Blue skies, mild temps and warm sunshine welcomed turf professionals to the South Florida Turfgrass Field Day and Expo at the beautiful University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Fort Lauderdale Research and Education Center (FLREC) in Davie on Thursday, March 21, 2019.

This event marks 31 years that the UF/IFAS Turfgrass Science Team has been providing attendees, including golf course superintendents, athletic field managers, sod farmers, and landscape maintenance crews, with the latest information, research and technology available that is needed to manage turfgrasses most effectively, efficiently and environmentally friendly.

Walking field tours of research plots filled the morning, giving participants ample opportunity to get their steps in while learning about turf insect and disease management, nutrient and herbicide interactions, best management practices (BMPs), and cultivar breeding evaluations.

Field tour participants were separated into two groups, either those interested in ‘golf and athletic’ management or ‘landscape’ management, and presenters catered the information in a rotating fashion to those two management needs. I chose the ‘golf and athletic’ focused tour, and here are highlights from the seven field stops.

Stop 1. Breeding Improved Turgrass Cultivars for the Golf and Sports Industry

Dr. Kevin Kenworthy, UF/IFAS Turf Breeder, showcasing his zoysiagrass and bermudagrass cultivar field trials during the South Florida Turf Field Day and Expo at the UF/IFAS Ft. Lauderdale Research and Education Center on March 21, 2019.
Dr. Kenworthy talks Tiftuf and comments how it has proved to be the most drought tolerant cultivar.
Dr. Kenworthy provided an excellent handout with summarized results for turf quality, color and disease reaction from trial locations across Florida including UF/IFAS FLREC, the UF/IFAS Central Florida Research Center in Citra and the UF/IFAS North Florida Research Center in Jay.

Stop 2. Disease Management in Warm Season Turfgrasses

Dr. Harmon’s talk was one that would make any plant disease enthusiast beam with wonder and fascination from all the mentions of cool spores, emerging viral diseases, and other diseases that are not as they have seemed! Lethal viral necrosis, mini ring and bermudagrass decline? Oh my! These are three diseases all turf managers should have on their radar. Below are links to more information about each of these diseases.

Mini Ring: http://gsrpdf.lib.msu.edu/ticpdf.py?file=/2010s/2010/100114.pdf

Bermudagrass Decline: https://edis.ifas.ufl.edu/pdffiles/LH/LH07900.pdf

Dr. Phil Harmon, UF/IFAS Turf Pathologist, discusses bermudagrass decline associated with Magnaporthe that’s been intriguing turf pathologists with its occurrence in samples recently.

Stop 3. New Tools for Managing Turf Insects

Dr. Adam Dale, UF/IFAS Turf and Ornamental Entomologist, discusses reduced-risk pesticides and their dual control capability to turf field day attendees.

Dr. Dale presented the latest information on turf insect pest management, particularly for bermudgrass mite, tuttle mealybug and mole crickets. He highlighted three new reduced-risk pesticides chemistries available for pest management that are safer for pollinators and other beneficial organisms (see handout below). Dr. Dale explained by using these types of reduced-risk pesticides, you can achieve dual pest control with direct chemical toxicity and biological control from conserved predators. #UFBUGS

Stop 4. Herbicide and Nutrient Interactions

Lucas Maia, UF Master’s student in Ft. Lauderdale, presents his herbicide and nutrient interaction trial results with attendees at the UF/IFAS South Florida Turf Field Day and Expo on March 21, 2019.

Stop 5. Golf Industry Best Management Practices: A Worthwhile Effort?

Mark Kann, University of Florida, giving field day attendees the golf course BMP low-down.

Mark’s stop provided an under the tent discussion on the current golf course BMP program and gave attendees some hot off the press, preliminary survey results from the recently conducted BMP email survey.

The golf course BMP program is a first of it’s kind with the University of Florida’s Dr. J. Bryan Unruh leading the charge since 2009. The program is a voluntary, 7-hour course that ends with a certification exam that if passed is valid for 4 years. A recent survey was sent out to turf industry professionals with the goal to get information that will help improve the program.

Mark stated that 79% of survey respondents stated they have been through the program, while 19% were not but plan to be, while 2% said they were not and do not plan to be. Scheduling conflicts, time constraints, and the fact that the program is a voluntary program were the main reasons listed for courses not being enrolled in the program.

Currently, 472 golf courses in Florida are BMP certified, and according to Mark, that is not enough. He encourages sharing knowledge of the program with those who may not be aware. Awareness is key, he says.

Stop 6. Bahiagrass Improvement Program: What’s the Status of the New Lines?

Agustin Boeri presents his Master’s research on bahiagrass improvement.

Stop 7. Improved Bermudagrass Cultivar Response to Drought and Fertility

Last but not least we stopped at Dr. Jason Kruse’s improved bermudagrass cultivar response to drought and fertility field plots.

Dr. Jason Kruse, UF/IFAS Turfgrass Specialist, talks low fertility and turf color. Although color looks good with low fertility in these plots, the growth may not be adequate.

Vendor updates, equipment demonstrations and a BBQ lunch followed the field tours. .

The afternoon was for indoor educational workshops with your one hour choice between Enhancing Pollinator Protection in the Urban Environment, with Dr. Adam Dale, Testing Your Knowledge of Pesticide Safety and Laws, with Dr. J Bryan Unruh, or Golf and Landscape Nutrient Best Management Practices with Dr. Laurie Trenholm.

I chose Dr. Dale’s pollinator talk, and it was quite enjoyable. I was impressed with how engaged the audience was with his talk. He has done some really cook projects with increasing pollinator habitats with wildflower plantings on some golf courses that I hope to bring to Brevard County.
