EPA approves Syngenta's Viptera 3220 stacked maize

The US EPA has approved Syngenta’s genetically modified stacked insect-resistant and herbicide-tolerant Agrisure Viptera 3220 maize. The product has a dual mode of action against above and below ground lepidopteran pests, and a 5% structured refuge requirement. It combines Syngenta’s Bt Vip3A toxin, Bt11 (Cry1Ab) and DuPont/Dow AgroSciences’ Herculex 1 (Cry1F), providing tolerance to the herbicides, glyphosate and glufosinate-ammonium. Syngenta plans a commercial launch of hybrids this autumn for planting in the 2012 season. It has also been approved for cultivation in Canada and Brazil, and is authorised for import into Australia, Canada, Mexico, the Philippines, Japan, Taiwan and South Korea. Syngenta has also applied for EPA approval of a 5% blended refuge-in-a-bag version of the Agrisure Viptera 3220 trait stack ( Agrow No 610, p 22). That will be marketed under the name Agrisure E-Z Refuge.
