Stressgard combats golf courses’ abiotic and biotic stresses immediately and in the long term.

Simply put, there is no counterpart to Stressgard — a proprietary stress-mitigating technology unlike anything else on the market.

Stressgard’s unique properties have helped thousands of superintendents across the United States significantly reduce abiotic stress and improve turf health for more than 20 years.

But contrary to some superintendents’ beliefs, Stressgard is not an active ingredient. It is a proven technology that is available in a portfolio of fungicides. It can improve the quality of turf — inside and outside — on a short- and long-term basis.

“On the inside, it helps turf sustain chlorophyll stability. By maintaining photosynthesis, plants can better withstand and recover from stressful conditions,” says Chenxi Zhang, Ph.D., product development manager at Bayer. “On the outside, it improves color and helps turf manage solar radiation under various conditions — during the peak of summer or under shade.”

As a result, turf can continue to produce food despite tough conditions — leading to a decrease in root loss, enhanced root function and water utilization, delayed wilting and, ultimately, greener turf for a much longer time.

Furthermore, because it is formulated with a variety of fungicides, Stressgard can be easily incorporated into superintendents’ current programs without interrupting or delaying them.

Versatility time after time

Paul Giordano, Ph.D., Green Solutions Team specialist at Bayer, has conducted on-site trials of Stressgard with superintendents across the country.

“The best way to show superintendents the benefits of Stressgard is to bring it to them,” Giordano says.

As director of course maintenance at The National Golf Club of Kansas City, which features two private 18-hole courses, The National and The Deuce, Spencer Roberts has seen the positives of Stressgard firsthand. Not only did he use it for several years at facilities in Arkansas and Nebraska, but he also has appreciated the technology’s versatility whenever he and his staff members have applied it at The National Golf Club.

“At the start of the season, usually between late March and late April, we use Tartan Stressgard. Then we’ll switch Tartan with Interface Stressgard or Signature XTRA Stressgard throughout the summer,” Roberts explains. “And then we’ll finish the season with Mirage Stressgard, which we’ve also implemented with some of our roughs.”

This versatility in rotation has led to higher quality turf year-round, as Roberts rotates his fungicides throughout the summer, he says. Typically, he does not use each Stressgard product longer than two weeks at a time.

“Ninety-nine percent of the products are used on our bentgrass/Poa greens,” he adds. “They remained healthy this year, even though we had an extreme drought for six weeks during the summer.”

Consistent, long-lasting results

In addition to offering superintendents versatility, Stressgard also delivers consistent results. Each time the technology is used, it rapidly improves turf color and vividness. It contains a proprietary pigment unique to Bayer that provides a positive visual effect once a Stressgard product is applied.

A few days after the application, the visual appearance of the pigment dissipates, so superintendents will only notice positive changes due to Stressgard’s ability to improve the turf’s natural functions.

These fast-acting benefits are also long-lasting. The plant’s chlorophyll stability and photosynthetic activity are improved considerably, leading to a much higher quality in turf color, density and overall health long term, regardless of weather conditions.

“Most fungicide products don’t result in a recognizable improvement in turf quality just after application,” Giordano says. “But Stressgard does, while also improving certain physiological functions in the turf longer term.”

Exceeding golfers’ expectations

A superintendent’s primary goal is to exceed golfer expectations at the course. And nothing satisfies a golfer more than a beautiful, first-rate golf course that is enjoyable and playable every day of the season.

To ensure courses’ color, quality and playability exceed customers’ expectations, Stressgard not only combats turf’s biotic (fungal) stresses, but its abiotic stresses as well, including:

“By using Stressgard, superintendents will deliver satisfaction to their customers — the golfers — over and over again,” Zhang says.

Stressgard technology can be found in a wide variety of golf course management products from Bayer.

“Every superintendent in the United States can benefit from Stressgard,” Giordano says. “Since the technology can address a wide range of abiotic stresses, each superintendent should be able to find a product that addresses their specific need within the Stressgard portfolio.”
