What is Bollgard 3?
Bollgard 3 will make growing cotton easier as it allows growers to manage their crop with more flexibility. The addition of a third gene reduces the existing resistance management requirements allowing growers to plant more cotton.
The addition of a third protein, Vip3A, reinforces the Bt proteins found in Bollgard II® – Cry1Ac and Cry2Ab. Having three proteins will increase the longevity of the technology, with each having a different mode of action or ‘kill’ the larvae in a different way.
The addition of the third protein increases the sustainability of the technology as it becomes increasingly difficult for Helicoverpa to develop resistance to more than one of the Bt proteins.
