The Next Evolution Is Here: Envu® Announces Signature™ XTRA Stressgard® Liquid Fungicide Is Now Available for Purchase
Driven by golf course superintendent feedback. Delivered through global innovation.
Cary, N.C., July 22, 2026 — The wait is over. Signature™ XTRA Stressgard® Liquid fungicide — the new first-of-its-kind liquid formulation of fosetyl-Aluminum (fosetyl-Al) from Envu® — is now available for golf course superintendents. Developed specifically for the golf and fine-turf market, Signature XTRA Stressgard Liquid is designed to deliver the proven performance golf course superintendents expect from Signature XTRA Stressgard in a more convenient, easier-to-use formulation and marks the next chapter in one of golf's most trusted plant health and disease management brands.
“Signature and Stressgard products have earned the trust of golf course superintendents over many years for many reasons,” said Jeff Kwiatkowski, head of Turf and Ornamental – US, Envu. “Customers have been begging for a liquid formulation of Signature XTRA Stressgard fungicide to improve their application experiences and overcome the challenges with traditional formulas. No one in the world has the dedicated resources and focus to generate this one-of-a-kind solution. At Envu, we start with the customer, and within our Turf and Ornamental team, we obsess over making the superintendents' jobs easier. This product does that and more.”
Global Innovation Effort
The availability of the new liquid fungicide represents more than a new product launch — it is the culmination of 12 years of research, development and global collaboration driven by a simple goal: make the solution that golf course superintendents rely on even easier to use. Drawing on a legacy that spans more than four decades of fosetyl-Al innovation and nearly three decades of Signature fungicides, Envu scientists and formulation experts from North America and Europe overcame significant technical challenges to bring this liquid formulation to market.
“Envu innovation doesn’t stand still even with already successful solutions,” said Mark Schneid, head of North America, Envu. “By transforming this trusted chemistry into a liquid formulation, we are providing greater convenience, consistency and ease of use while preserving the performance that golf customers have come to expect. This launch reflects our commitment to continuously improving solutions that help our customers succeed.”
Key Benefits of Signature XTRA Stressgard Liquid
Signature XTRA Stressgard Liquid is a true systemic fungicide that enhances plant health, helping cool- and warm-season turfgrass withstand both biotic and abiotic stress. It is the cornerstone of disease and plant health programs in greens, including Pythium diseases, anthracnose, Microdochium patch, algae suppression, leaf spots and bermudagrass decline.
Additional benefits of Signature XTRA Stressgard Liquid include:
- A new easy-to-mix liquid formulation that offers a more natural green turf color.
- Proven Stressgard technology that boosts photosynthesis while improving tolerance to abiotic stresses such as traffic, heat, shade, winter injury and low mowing.
“We are incredibly proud of our powerhouse innovation team for solving customers' needs,” said Patrick Burgess, Ph.D., solution development lead Turf and Ornamental, Envu. “Golf course superintendents tell us the new liquid formulation is increasing efficiency for their crews — they pour it in and go — no foaming, no clogged sprayers. All this while expanding the label to microdochium patch and algae suppression which are two important needs that we heard echoed from our customers, it’s truly exciting for the entire global golf industry.”
Signature XTRA Stressgard Liquid is available in the U.S. and will expand to in Canada in 2027, further building on the long-standing legacy of Signature and Stressgard technology formulation.
