Bt Corn

Bt Corn: How have humans used Bt corn to change the world?

Humans have used Bt corn to help reduce the need for pesticide. Use of Bt corn has saved US farmers in Iowa and Nebraska alone up to 1.7 billion dollars in fighting this pest over the past 14 years. A reduction of 13 million kg of pesticide in the United States has been recorded in soybean and corn fields in between 1997 and 2009, after the introduction of genetically modified crops. A reduction of 13 million kg of pesticide Bt crops also decreases pesticide usage.

How have humans used Bt corn to change the world?

Bt produces a protein that paralyzes the larvae of some harmful insects, including the cotton boll worm and the Asian and European corn borers. Bt has been used as an insecticide by farmers worldwide. Bt crops are an addition to our arsenal against plant pests. A unique feature of this bacterium is its production of crystal-like proteins that selectively kill specific groups of insects.

How have humans used Bt corn to change the world?

Bt crops are an addition to our arsenal against plant pests. With an increasing population and decreasing arable land, it is necessary to exploit all options with as little compromise to produce more crops. Rapid introduction of Bt corn hybrids creates uncertainty about the technology and new questions about its use. While the primary benefit comes largely during a heavy corn-borer infestation, a secondary effect is that beneficial insects fare much better under these conditions.
