From Customer Insight to Innovation: Michael McCormick and Oakmont Country Club Put Signature™ XTRA Stressgard® Liquid to the Test

When golf course superintendents search for ways to improve turf health, streamline spray operations and manage plant stress, they need solutions that perform under pressure. At Oakmont Country Club, one of the most recognized golf courses in the world, those demands are elevated every day. Oakmont's grounds team maintains elite playing conditions on predominantly Poa annua greens while managing environmental stress, mechanical wear and the expectations that come with a championship-caliber venue.

To see these challenges firsthand, watch our latest Insight to Impact video featuring Michael McCormick, Grounds Superintendent at Oakmont Country Club. McCormick shares how Signature™ XTRA Stressgard® has become a cornerstone of Oakmont's turf management program and discusses the potential benefits of the new liquid formulation, including easier mixing, improved operational efficiency and the trusted performance superintendents have come to expect

For decades, Signature™ XTRA Stressgard® fungicide has been a trusted part of turf management programs, helping golf course superintendents support plant health and resilience throughout the growing season. At Oakmont Country Club, Grounds Superintendent Michael McCormick calls Signature XTRA the "backbone" and "foundation" of the club's spray program, helping turf withstand heat, humidity, drought stress, and the rigors of frequent mowing and rolling.

But one question continued to surface across the golf industry: What if Signature XTRA were available in a liquid formulation?

According to McCormick, golf course superintendents had been discussing that possibility for years. Envu® listened. Driven by customer feedback and a commitment to delivering practical innovation, Envu invested years of research and development to bring Signature XTRA Stressgard Liquid fungicide to market.

Today, Oakmont is experiencing the benefits of the new formulation. The team reports comparable fungicide performance, plant health benefits, turf quality, color and pigment performance, while gaining operational efficiencies through easier mixing, improved tank-mix compatibility, and faster spray preparation. For golf course maintenance teams, every minute matters, and simplifying the spray process can help crews focus more time on course presentation and playability.

The development of Signature XTRA Stressgard Liquid demonstrates how customer insights can drive meaningful innovation. By partnering closely with golf course superintendents and understanding the realities of modern turf management, Envu continues to develop solutions that help optimize efficiency while supporting healthy, resilient playing surfaces.
