For golf course superintendents, the new liquid formulation represents more than a product launch. It is the latest evolution of a proven innovation that has helped turf managers navigate summer stress, disease pressure and demanding playing conditions for decades.
Why Signature Became a Turf Management Staple
The history begins in the transition zone, where managing creeping bentgrass through summer heat has long challenged superintendents.
According to Kerns, early work at NC State helped establish programs that combined disease control and plant health benefits, providing new ways to protect turf during periods of intense stress. Signature fungicide ultimately became a foundation of those programs and continues to play a critical role today.
"I don't think there's a bentgrass plant that doesn't see Signature anymore," says Kerns. "It's literally our base recommendation."
That recommendation extends beyond disease management. Research has shown value across a range of turf stress challenges, including Pythium root rot, anthracnose suppression, take-all root rot and mini-ring management when incorporated into a comprehensive program.
What Makes Signature XTRA Stressgard Liquid Different?
While previous formulations earned widespread adoption, golf course superintendents frequently shared feedback about mixing and handling challenges associated with dry formulations.
Signature XTRA Stressgard Liquid was developed to address that need.
The liquid formulation is designed to simplify the application process by:
-
Mixing more quickly
- Eliminating the need to dissolve a dry product before application
- Helping golf course superintendents save valuable time
"What we've heard from golf course superintendents no matter where we've done a demo is how fast it is to mix," says Benelli.
For golf course maintenance crews operating in the early morning hours, even small efficiencies can have a meaningful impact on productivity and course operations.
The Importance of Consistency
One of the key themes is that the benefits of Signature are realized through consistent use as part of a broader turf management strategy.
Kerns notes that success often comes from applying products before stress symptoms appear and maintaining programs throughout the season. Research conducted at NC State has demonstrated benefits on both cool- and warm-season turf when applications are properly timed.
"The key with using Signature XTRA Stressgard Liquid is consistency," says Kerns. "To really realize the benefit is to use it on a consistent basis."
For creeping bentgrass, that can mean applications leading into summer stress periods. For bermudagrass putting greens, research has identified opportunities to support fall health, spring green-up and seasonal transition.
Research-Driven Innovation
One reason Signature has remained relevant for decades is the ongoing collaboration between industry and university researchers.
Envu works closely with leading turfgrass scientists to validate product performance under real-world conditions. University trials help evaluate disease control, plant health benefits, mixing characteristics and program fit before solutions are brought to market.
That commitment to research has helped shape the evolution of Signature from its original formulation to Signature XTRA Stressgard, and now Signature XTRA Stressgard Liquid.
As Kerns points out, every reformulation represents years of testing, investment and refinement aimed at helping superintendents succeed.
One Word: Dependable
When asked to describe Signature XTRA Stressgard Liquid in a single word, both experts arrived at the same answer.
For Kerns, that dependability comes from decades of consistent performance and a track record of helping superintendents manage challenges across a variety of turf conditions. For Benelli, it reflects the confidence that comes from years of research and validation before launch.
As the next chapter of Signature technology begins, the goal remains unchanged: helping golf course superintendents protect turf, manage stress and deliver exceptional playing conditions season after season.
