GMO multi-toxin crops continue to backfire as more insects become resistant to crop chemicals

 Published in the journal Proceedings of the National Academy of Sciences, the new study explains how multi-toxin GM crops are quickly losing their ability to fend off pests, which could lead to a complete GMO failure in the very near future if alternate interventions are not enacted.

The study evaluated specific GM crops like corn and cotton that have been infused with a genetic mutation involving the bacterium Bacillus thuringiensis (Bt), as well as several other toxins that grow inside the plant to target pests. This so-called "pyramid" strategy, which involves using multiple GM toxins to target the same pests, is said to have been designed for the purpose of thwarting pesticide and insecticide resistance by targeting pests with two or three different toxins all at once rather than just one at time.
