One of the nation's most widely planted crops — a genetically engineered corn plant that makes its own insecticide — may be losing its effectiveness because a major pest appears to be developing resistance more quickly than scientists expected.
The U.S. food supply is not in any immediate danger because the problem remains isolated. But scientists fear potentially risky farming practices could be blunting the hybrid's sophisticated weaponry.
When it was introduced in 2003, so-called Bt corn seemed like the answer to farmers' dreams: It would allow growers to bring in bountiful harvests using fewer chemicals because the corn naturally produces a toxin that poisons western corn rootworms. The hybrid was such a swift success that it and similar varieties now account for 65 percent of all U.S. corn acres — grain that ends up in thousands of everyday foods such as cereal, sweeteners and cooking oil.
But over the last few summers, rootworms have feasted on the roots of Bt corn in parts of four Midwestern states, suggesting that some of the insects are becoming resistant to the crop's pest-fighting powers.
