PROJECT NAME:
Late Fall Topdressing as a Practice to Mitigate Winterkill
Payton Perkinson, Eric Galbraith, and Kevin Frank (Michigan State University), Doug Soldat (University of Wisconsin), and Alec Kowaleswski (Oregon State University)
Late fall sand topdressing applications have become a common practice in many regions as a possible deterrent to winterkill. There is little if any data from trials to either support or refute the benefit of these applications. In the fall of 2023, topdressing applications were made to putting greens at turfgrass research facilities in Iowa, Michigan, Minnesota, Wisconsin, and Norway and on a golf course in Oregon to determine the effects of late fall sand topdressing. The sand topdressing rates applied were none, 3 ft3 sand /1000 ft2 (normal rate), and 6 ft3/1000 ft2 (high rate). Topdressing was applied in a single application after the final mowing of the season and before the first anticipated snowfall. Response variable such as surface temperature, percent winter damage and turfgrass quality were assessed within the fall topdressed plots and were compared to plots that were not topdressed. Data were collected after spring snow melt until spring aerification.
Results were mixed across diverse locations, but some commonalities were found in the 1st year of treatments. Surface temperatures were higher for the high topdressing rate treatments which may result in increased biological activity for snow mold pathogens. At the Wisconsin location this was in fact the case with more snow mold on the high topdressing rate treatments. At the Oregon location, surface temperature and quality increased with topdressing rate, while winter damage decreased with increasing topdressing rates. As of April 11, three weeks after snow melt no differences in winter damage were visible at the Oregon location. This was a very mild winter across all locations so the research will be repeated over the 2024-2025 season.
This project was supported by the National Institute of Food and Agriculture, U.S. Department of Agriculture, Specialty Crop Research Initiative under award number 2021-51181-35861.
PROJECT NAME:
MSU showcases turfgrass tech ahead of the FIFA World Cup 26
In 2026, Michigan State University will play a major role in one of the biggest sporting events in the world by teaming up with The Fédération Internationale de Football Association, or FIFA.
MSU’s internationally recognized turfgrass management program has received a second invitation from the FIFA to provide playing surfaces for the FIFA World Cup 26.
The fLEX (foot lower extremities) machine to test the turfgrass plots
On Oct. 2, MSU hosted a field day along with FIFA and partners from the University of Tennessee for stadium managers and sod farmers who will oversee installing, removing and transporting the natural turfgrass for the 2026 games.
Guests were able to see the turfgrass that is currently being grown and how the natural surface is being tested using the foot lower extremities or fLEX machine that mimics the rigors of gameplay using a cleat to ensure it meets FIFA’s industry standards for field consistency.
With the grant funding investment from FIFA, the challenge for turf teams at MSU and the University of Tennessee involves developing effective and consistent fields for competitive play across three host countries — U.S., Canada and Mexico — in over 16 cities with diverse climates for 104 games.

“The fact that MSU’s turfgrass program was asked to participate and was selected for a second time shows our expertise and leadership in this field,” said John “Trey” Rogers III, a professor of turfgrass research in MSU’s College of Agriculture and Natural Resources. “FIFA’s research support for the 2026 World Cup will allow us develop and perfect temporary turf even further and to usher in an unbelievable era.”
Three decades ago, Rogers played a role in the 1994 FIFA World Cup when his team installed a temporary grass field at the Pontiac Silverdome for the first time. The challenge was to grow turfgrass indoors that could be installed and removed from a venue. Rogers and his team showed that portable turf is possible — an innovation of its time that has now become common in the industry.
“We always felt the pressure of this project,” Rogers said. “Specifically, in carrying forward sports turf innovations.”
Today, Rogers has partnered with John Sorochan, a Distinguished Professor of Turfgrass Science and Management at the University of Tennessee. Sorochan was a graduate student of Rogers’ and worked on the World Cup project in 1994. Now, Rogers and Sorochan are co-principal investigators for the 2026 competition.
For its part, MSU developed a cool season turfgrass mixture comprised of Kentucky bluegrass and perennial ryegrass that can be grown in sand on plastic, making it easier to replicate at sod farms across North America.
For Dave Betts, a co-owner with Tuckahoe Turf Farms in South Jersey who will be installing and removing the turfgrass for the New York, Boston and Philadelphia matches, this field day provided an opportunity to learn from the researchers growing the turfgrass and see and feel it for himself ahead of the FIFA World Cup 26 games.
“This was really impressive to see the turfgrass, learn about how it is reinforced and to see the drainage system for myself,” said Betts. “I also learned a lot about the research that went into how the turfgrass was grown and tested.”

The experience of growing turfgrass for the FIFA World Cup 26 also provides a unique opportunity for past and current students and technicians. Ryan Bearss, Jackie Guevara, Jake Kilby and Evan Rogers are all part of MSU’s turfgrass program, and the experience of participating in this project will stay with them forever.
“The work done from 1992 to 1994 led to 30 years of innovation and adoption by the turfgrass science industry,” said Brian Horgan, professor and chair of the MSU Department of Plant, Soil and Microbial Sciences. Horgan was also an undergraduate student of Rogers’ during that time and worked on the first FIFA project. “It was an important experience in my career,” Horgan said. “I still talk about it.”
Listen to Trey and John talk about their experiences growing turfgrass for the World Cup in 1994 and for 2026 with Russ White on the MSUToday podcast.
