Twinlink Dual Bt Cotton Technology - Performance Across The Globe

Bayer CropScience is developing the in-house stacked Bt product TwinLink^™, expressing both cry1 and cry2 genes, conferring protection from damage of a wide range of Lepidopteran pests, as well as tolerance to glufosinate ammonium (Liberty^®) herbicide. Contingent upon regulatory approvals, TwinLink cotton stacked with GlyTol^® technology is planned for commercial release in the US in 2014. 

Since 2006, extensive field testing of TwinLink^™ and GlyTol^® x TwinLink^™ (GLT) cotton has been undertaken internally and with third parties in the US, in Brazil and Argentina, the EU (Spain), India and Australia. Trials with TwinLink cotton have recorded solid efficacy against a number of key Lepidopteran pests of cotton, including H. zea, H. virescens, H.armigera, S. frugiperda, S. exigua S. littura and P. gossypiella.  This presentation reviews the insect efficacy of TwinLink^™ and GLT cotton around the world. 

Once approved and available in elite Bayer CropScience germplasm, these technologies will provide US cotton growers with greater choice and flexibility for weed and insect management. GLT cotton will provide cotton growers with stacked insect protection as well as stacked herbicide tolerance.
