Bt11, a GM Bt and herbicide-tolerant maize owned by Syngenta, produces the Bt toxin Cry1Ab against lepidopteran pests (moths and butterflies), mainly European corn borer (ECB, Ostrinia nubilalis) and Mediterranean stem borer (MCB, Sesamia nonagrioides). In addition, Bt11 is herbicide-tolerant against the glufosinate-ammonium (BASTA, Liberty).In its application for cultivation in the EU, Syngenta claims that Bt11 will not be marketed for its herbicide tolerance, but in other countries, such as the USA and Canada, the maize is marketed for both GM traits.
In October 2007, the EU Environmental Commissioner Dimas proposed to reject the application. The EU Commission has taken no decision yet but referred it back to the EFSA who in Oktober 2008 once again gave a positive opinion.
