Genetically modified corn is ineffective

Genetically modified corn - a plant created to resist pests - may be losing its effectiveness when pests can adapt to new plants.

Harvesting corn in the US

When introduced in 2003, Bt corn seems to have met the farmer's dream: to bring bumper crops while requiring less chemicals because it itself has produced toxins to destroy. bugs. This hybrid corn variety now accounts for 65% of corn cultivation area throughout the United States. But over the past few summers, rootworms have rapidly reproduced in Bt corn roots grown in parts of the four central western states. This suggests that insects are losing the insect resistance trait of Bt corn.

The Mosanto company created Bt corn by cultivating the Bacillus thuringiensis worm gene into corn. Insect repellents are naturally produced without harming humans and livestock. The deep root process will develop the ability to resist the toxin produced by this gene that has occurred faster than the scientists think.
