Bayer CropScience’s TwinLink® cotton technology receives full authorization in the US
Milestone for stacked insect-resistant, herbicide-tolerant cotton
TwinLink technology combines insect-resistance for effective management of a number of
lepidopteran pests (caterpillars) and tolerance to glufosinate-ammonium herbicides (Liberty®). When
commercialized, TwinLink technology will be offered to US cotton growers as a stack with GlyTol®,
the company’s proprietary glyphosate tolerance technology. This stacked product will be the
industry’s first dual-gene herbicide tolerance, dual-gene insect resistance solution for cotton,
allowing farmers to manage the pests and weeds that reduce yields and fiber quality, as well as
prevent or postpone the onset of weed and pest resistance.
"TwinLink technology will be an important solution for cotton farmers looking to improve
their crop management choices and increase their productivity in a sustainable way. It is also a
critical tool for effective weed and insect resistance management - a serious challenge facing
growers in the US and increasingly in other important production areas around the world,” said
Mathias Kremer, Head of the BioScience business unit of Bayer CropScience.
It is anticipated that the first cotton varieties with the TwinLink and GlyTol stacked traits
will be available in the US from 2013 onwards, pending additional regulatory approvals in key
import countries. To date, TwinLink has been approved in Australia/New Zealand, Brazil, Canada and
the US. Additional regulatory approvals are pending globally.
TwinLink is the next product in a series of new weed and insect management solutions being
developed for the cotton farmer by Bayer CropScience. In 2011, the company launched three new
cotton products containing GlyTol in high-performance FiberMax® cotton seed varieties in the US,
including the cotton industry’s first combined dual herbicide tolerant varieties featuring both
GlyTol and LibertyLink- technologies.
Cotton is one of the key crops at Bayer CropScience, which ranks first in the world cotton
seed market.
