Syngenta and M.S. Technologies, L.L.C. announced plans to introduce a new herbicide-tolerant soybean trait stack designed to give growers substantially more flexibility and resilience in weed control programs. Broad commercial availability is targeted later this decade, pending all regulatory approvals.

What’s in the stack: Built on the proven Enlist E3® soybean event, the trait stack is designed to provide tolerance to a wider array of active ingredients than current market options, including:

• Glyphosate
• Glufosinate
• 2,4-D choline
• Multiple HPPD inhibitors (with stated examples including mesotrione, isoxaflutole and bicyclopyrone)

Why this matters: Adding HPPD inhibitor tolerance—chemistries widely and effectively used in corn—opens new early-season options in soybeans and supports diversified, multi-mode-of-action programs to slow resistance development.

Industry context: U.S. soybean growers continue to face herbicide resistance pressure and inconsistent early control, particularly under delayed planting or in fields with dense, mixed weed spectra. By stacking tolerance across several modes of action, the new trait aims to simplify programs, reduce crop-injury risk, and improve residual layering.

Commercialization & branding: Pending approvals and field advancement, Syngenta plans to commercialize through Golden Harvest® and NK® seed brands, with additional licensing via GreenLeaf Genetics®. M.S. Technologies indicates availability through Stine® Seed Company, Merschman Seeds®, Latham® Hi-Tech Seeds, and licensing via Peterson Genetics.

Voices from the companies: Syngenta leaders frame the stack as the “future of weed control flexibility” in soybeans, pairing the broadened tolerance profile with their genetics and crop-protection portfolio. M.S. Technologies highlights the combination of its FG72 trait lineage (formerly marketed as GT27®) with Enlist E3®, emphasizing a robust and highly flexible weed-control solution for growers.

Practical takeaways for growers:

• More tools, same crop: Post-emergence and residual options expand with HPPD tolerance added to glyphosate, glufosinate and 2,4-D choline programs.
• Program durability: Multiple effective modes of action help protect key actives and manage a broader weed spectrum (e.g., Palmer amaranth, waterhemp, ragweeds, grasses).
• Operational flexibility: Early-season HPPD options can backstop weather-driven delays or seed changes without restarting whole programs.

What to watch next: Regulatory reviews, trait stewardship guidelines, and herbicide-label alignments will define where and how the stack can be used. Retailers and advisors should prepare updated weed-management templates that incorporate HPPD options alongside existing Enlist E3® programs, with attention to residual layering, application windows, and resistance-management best practices.
