An agency investigation says a genetically modified version of corn may be losing its effectiveness to ward off rootworms in Minnesota and three other big corn-producing states. The pest may be developing a resistance to the plant's pesticide. Business Week says the bug is among the most destructive corn pests and costs farmers about $1 billion a year.

High prices have farmers all over the country boosting corn acreage. Minnesota expects about a ten percent increase over last year.
