Company Archer Daniels Midland Co. has filed a lawsuit against the Swiss company Syngenta seeds AG due on sales of genetically modified varieties of corn, unresolved import in China, joining more than 100 farmers and exporters in order to recover damages.

Syngenta is accused entered in the commercial appeal maize MIR162, also known as the Agrisure Viptera without creating an effective control program that corn did not hit the markets where prohibited.

Last year, China has refused to supply more than 1 million tons of U.S. corn and products made from corn, because they contained MIR162.

This type of corn produced approximately 3% of the agricultural area of the USA in the last two years, can be found throughout the U.S. supply chain, because it was not separated from other varieties starting in 2011.

Waiver of supply has led to very significant losses to U.S. exporters, including tens of millions of dollars of losses ADM.

The lawsuit ADM argues that Syngenta is not effectively exercised control program designed to prevent the sort of MIR162 in export channels, while all major foreign markets will not give permission to import.

Syngenta announced that the charges are not substantiated.

Colleagues on the export of grain, Cargill Inc and Trans Coastal Supply Co also sued Syngenta, seeking monetary compensation in connection with the refusal of China from the supply.

Last month, American farmers have filed class-action lawsuits seeking monetary compensation, since suffered losses from lower prices for corn because of a failure in the trade, estimated at $1 billion.
