About Syngenta and Agrisure Viptera®

Agrisure Viptera®

Engineered to eliminate a broad spectrum of above-ground pests—including corn earworms, western bean cutworms, and black cutworms—Syngenta’s Agrisure Viptera® corn variety contains the MIR 162 genetic trait that is currently not approved for export to China. Spiros Law, P.C., has found that Agrisure Viptera® was planted on nearly 2.85 million corn acres in the U.S. within each of the previous two years.

Agrisure Duracade™

Intended to protect corn root systems from Western, Northern, and Mexican corn rootworms, the Agrisure Duracade™ corn variant possesses both the MIR 162 genetic trait and an additional trait, the Event 5307, that has not yet been approved by China.


The product of a 2000 merger between Novartis Agribusiness and Zeneca Agrochemical, Syngenta is a global agribusiness involved in genomic research and biotechnology. As an industry leader in the production and engineering of agrochemicals and seeds, Syngenta was ranked third in sales for total sales of biotechnology and seeds in 2009.

The Agrisure Viptera® and Agrisure Duracade™ corn variants have both been sold in mass quantities to U.S. farmers despite Syngenta’s knowledge that the MIR 162 and Event 5307 genetic traits have not yet been approved by China, one of the largest and most rapidly expanding export markets for U.S. corn farmers.

At Spiros Law, P.C., we believe that this action has directly depressed the corn market in the United States, resulting in serious financial losses for U.S. corn farmers. If you have grown corn since November 2013, you may have been affected by Syngenta’s actions, and as such, you may be eligible for financial compensation for the losses you have suffered.
