Bayer seeks to test TwinLink cotton in Australia
Bayer CropScience has applied to the Australian Office of the Gene Technology Regulator (OGTR) to conduct small-scale field tests of its genetically modified insect-resistant and herbicide-tolerant TwinLink cotton. The cotton expresses the Bt Cry1Ab and Cry2Ae toxins for the control of lepidopteran pests and tolerance to Bayer’s herbicide, Liberty (glufosinate-ammonium). The company plans to test the cotton at a 0.1 ha site in New South Wales in 2008-09 to assess the control of cotton bollworms ( Helicoverpa armigera). The OGTR plans to issue a risk assessment in October. TwinLink cotton has undergone preliminary tests in the US, the OGTR points out. Last year, Bayer applied to test GM cotton expressing Bt Cry1Ab and Cry2Ae toxins under a US permit ( Agrow No 528, p 19).
