US approval for Syngenta GM maize stack
Syngenta has received US EPA approval for its genetically modified insect-resistant and herbicide-tolerant Agrisure 3122 maize stack. It incorporates several established traits for the control of above- and below-ground pests as well as tolerance to the herbicides, glyphosate and glufosinate-ammonium. Syngenta will market the maize as Agrisure 3122 Refuge Renew. It expects a US launch for the 2012 growing season, subject to the receipt of key import market approvals.
