Syngenta Canada launches Vayantis corn and soybean seed treatment


Guelph, Ontario, Canada

  • Contains a new, highly effective mode of action with no known cross-resistance
  • Provides the most comprehensive Pythium control in corn and soybeans
  • Provides wide-ranging Phytophthora protection in soybeans as part of Vayantis IV seed treatment co-pack

Syngenta Canada Inc. is pleased to announce the launch of Vayantis®, a next-generation fungicide seed treatment that provides comprehensive Pythium protection in corn and soybeans. 

Vayantis contains picarbutrazox, a new active ingredient from a novel chemical class with no known cross-resistance in soybeans or corn. Compared to competitor fungicide seed treatment chemistries, picarbutrazox provides higher efficacy on Pythium pathogens at lower use rates. 

Field trials show Vayantis protects corn and soybeans against Pythium to help improve seedling emergence – as well as plant stand uniformity – even under heavy disease pressure.

“We have a proven track record of providing excellent fungicide seed treatments, and Vayantis represents our most effective Pythium solution,” says Karen Ullman, Seedcare Product Lead with Syngenta Canada. “Vayantis will help growers adopt reduced or low-tillage practices to protect their soil, plant targeted seed populations and avoid costly replants from poor emergence.” 

Vayantis IV seed treatment co-pack also provides strong Phytophthora protection in soybeans. 

Vayantis will be available in a Vayantis IV seed treatment co-pack. The co-pack combines picarbutrazox with three additional modes of action providing protection against Phytophthora and other key early-season diseases. 

“Phytophthora root and stem rot is one of the most significant diseases in many Canadian soybean growing geographies,” says Ullman. 

She adds that genes found in many commercial varieties don’t always provide sufficient protection against all the predominant Phytophthora pathotypes currently found in Canada. 

Coupled with genetic resistance, Vayantis IV provides growers with more robust, early-season protection against all known Phytophthora pathotypes in Canada. 

“Under high disease pressure conditions, such as cool, wet weather, plants treated with Vayantis IV emerge faster and more uniformly,” says Ullman. “The comprehensive protection that Vayantis IV provides will also help growers protect the long-term viability of their Phytophthora genetics.”

Ullman encourages growers to talk to their local seed suppliers for more information about Vayantis and Vayantis IV, and how to get it on their corn or soybean seed in 2022. 

Always read and follow label directions.
