Bt-Corn: What it is and How it Works Ric Bessin, Extension Specialist Entfact-130 Bt-corn is a type of genetically modified organism, termed GMO. A GMO is a plant or animal that has been genetically modified through the addition of a small amount of genetic material from other organisms through molecular techniques. Currently, the GMOs on the market today have been given genetic traits to.An economic analysis of one variety of GM corn, called Bt corn, projected that farmers who planted the GM variety instead of non-GM corn could expect a 12% increase in revenue between the increased yield and the decrease in pesticides (Wu, 7-9). Of course, this goes hand in hand with the argument that GM crops will increase world food supply by artificially raising the number of crops that can.Bt corn, a genetically modified organism (GMO), has been both the poster-child and thorn-in-the-side of the plant biotechnology industry from the late 1990's to present. There are several versions of this transgenic crop that each have a gene from an insect pathogen, Bacillus thuringiensis (Bt), which encodes a protein toxic to the European corn borer (ECB), an insect pest that eats and.
Bt corn reduces the need for pesticides, and while the primary benefit comes largely during a heavy corn-borer infestation, an unpredictable event, a secondary effect is that beneficial insects fare much better under these conditions. The numbers are particularly impressive for Bt cotton: the spraying of almost 2 million pounds of pesticides—roughly 50% of previous usage—has been spared.The genes of Bacillus thuringiensis, or Bt, have been added to corn, cotton, potatoes, and other crops, with the desired results. Scientists are aware, however, that any effort to manipulate the ecological balance must reckon with the evolutionary consequences. So even before the first Bt crops were planted, scientists, farmers, and regulators began worrying about unintended effects. For.
Corn: the Ear-resistible Crop When you think about what makes the food industry capable of producing lots of greasy, diabetes-ridden food and selling it for extremely low prices, corn is not often what comes to mind. Corn is not the only source of cheap energy in the supermarket, but it is.
