Syngenta's VipCot heads for US market
Syngenta’s genetically modified insect-resistant VipCot cotton is to be introduced in the US through licensee seed companies next year. Clearance for commercialisation resulted from this month’s USDA deregulation of the COT67B event ( Agrow No 625, p 35). COT67B produces a modified Bt Cry1Ab toxin for the control of a range of lepidopteran pests. It is a component of VipCot cotton, together with COT102, which produces a Bt Vip3A toxin. Syngenta is licensing the individual traits and the VipCot stack to seed providers. It has licensed the Vip3A technology to Bayer CropScience, Dow AgroSciences and Monsanto for use in their cotton products ( Agrow No 596, p 3). “Providing multiple modes of insect resistance to growers will help prevent the development of resistant insects,” says Syngenta North America region director David Morgan.
