The seeds are not available on the European market for cultivation.
In the decisions, the missioner, Stavros Dimas, contends that the ically modified corn, or maize could affect certain butterfly species, specifically the monarch, and other beneficial insects. For instance, research this year indicates that larvae of the monarch butterfly exposed to the ically modified corn ''behave differently than other larvae.'' In the decision concerning the corn seeds produced by Dow and Pioneer, Mr. Dimas calls ''potential damage on the environment irreversible.'' In the decision on Syngenta's corn, he says that ''the level of risk generated by the cultivation of this product for the environment is eptable.''
A decision by the European Union to bar cultivation of the ically modified crops would be the first of its kind in the trade bloc, and would intensify the continuing battle over ically modified corn. Banning the applications for corn crops also would mark a bold new step for European environmental authorities, who are already aggressively pursuing regulations on emissions from cars and aircraft, setting it at odds with the United States and angering industries.
