In the decisions, the environment commissioner, Stavros Dimas,contends that the genetically modified corn, or maize could affect certainbutterfly species, specifically the monarch, and other beneficial insects. Forinstance, research this year indicates that larvae of the monarch butterflyexposed to the genetically modified corn behave differentlythan other larvae. In the decision concerning the corn seeds produced by Dow andPioneer, Mr. Dimas calls potential damage on the environment irreversible. In thedecision on Syngentas corn, he says that the level of risk generated by the cultivation of this product forthe environment is unacceptable.

　　A decision by the European Union to bar cultivation of thegenetically modified crops would be the first of its kind in the trade bloc,and would intensify the continuing battle over genetically modified corn.Banning the applications for corn crops also would mark a bold new step forEuropean environmental authorities, who are already aggressively pursuing regulationson emissions from cars and aircraft, setting it at odds with the United Statesand angering industries.

　　These products have been grown in the U.S. and other countries foryears, said Stephen Norton, a spokesman for the United States trade representative.We are not aware of any other case when a product has been rejectedafter having been reviewed and determined safe by European foodsafety authorities, he said.
