Syngenta, the Swiss agricultural giant, is introducing its new herbicide Virestina in Argentina this June, targeting herbicide-resistant grass weeds plaguing soybean and cotton fields. The move comes as farmers globally face escalating costs from weeds evolving to withstand common crop sprays. Virestina represents a significant push in a multibillion-dollar race among companies like Bayer and Corteva to develop new herbicides after years of limited innovation.

Syngenta, owned by China National Chemical, secured approval for Virestina in Argentina, the world's third-largest soybean producer, positioning it to capture a crucial market segment. The company aims to expand approvals to Brazil and Australia next, though the U.S. launch is expected later due to its stringent regulatory process.
