Consolidated Grain and Barge Co. and Archer Daniels Midland Co. announced they will not accept crops containing the trait until major importers approve it. This followed Cargill’s announcement that it will reject Duracade crops delivered to its grain elevators for export contracts. Bunge also says it will only handle crops that have been approved in major markets. Engineered to control corn rootworms, Duracade was approved by the U.S. Department of Agriculture last year and is now available for planting in the U.S. Reuters says the National Grain and Feed Association and North American Export Grain Association requested Syngenta suspend the commercial use of Duracade in the U.S. until export markets have granted regulatory approval, but Syngenta declined. Duracade does have import approval from other large markets, including Mexico, South Korea and Japan.
