Is Bt corn successful?

Corn hybrids with one or more Bt genes (Bt corn) are resistant to some important pests. Bt corn hybrids are a highly effective and economical alternative to conventional insecticide treatments, if targeted pest activity is at economically significant levels.

How does Bt corn increase crop yield?

Insect resistant crops (Bt crops) contain a gene from a soil bacterium, Bacillus thuringiensis, which produces a protein that is toxic to specific insects. … Over three-quarters of those farmers who had adopted Bt corn indicated that they did so to increase yields.

What is bad about Bt corn?

Are Bt crops safe?

The US EPA’s analysis of Bt crops finds that they pose no significant risk to the environment or to human health. Bacillus thuringiensis (Bt) is a naturally occurring soil bacterium that produces proteins active against certain insects.
