Recent reports of resistance to Bt crops in the western corn rootworm, western bean cutworm and other pests have raised fears of “superbugs” that cannot be killed using our established arsenal of Bt hybrids and traits.
In fact, resistance is a completely expected (but not unavoidable) outcome of using the Bt crops we have at our disposal. But all is not lost! While it is true that resistance is a growing concern, there are still steps growers and consultants can take to limit the risk of resistance evolving in their fields.
This 5-minute video covers a lot of ground, outlining how and why Bt crops are safe and valuable tools and the main factors causing resistance to develop. Watch it!
