Throughout the world, 560 million tons of corn are produced each year. Almost seven percent of the crop, over 39 million tons, never makes it to the market. This creates a significant financial burden on farmers. In the U.S. and Canada alone, corn damage and control costs are in excess of one billion dollars each year.
The reason such a large proportion of corn is destroyed is because an insect, the European corn borer, lays its eggs on the stalk and leaves of the plant. The newly hatched larvae feed on the plant, then chew a shallow layer of cells that is enough to damage the whole corn plant.
