Monsanto was quick to respond to the studies and to the U.S. Environmental Protection Agency’s (EPA) concern over “mounting evidence” their corn was no longer living up to its promise. Bloomberg Businessweek reported:
The studies of rootworms in Illinois and Iowa don’t confirm resistance in the field, Kelly J. Clauss, a spokeswoman for St. Louis-based Monsanto, said in an e-mail. More data is needed to prove resistance and the company is working with the EPA to investigate and respond to fields where rootworms cause “greater-than-expected damage,” Clauss said.
While Monsanto works with the EPA to figure out the extent of the problem and how to deal with it, the company has reason for concern. According to Bloomberg Businessweek, U.S. farmers planted the company’s Bt-corn on nearly 40 percent (37 million acres) of their cornfields. That is a major contribution to the company’s profits.
The biotech industry will respond the way it always does, by developing more chemical fixes to address the problem. Pete Riley of GM Freeze pointed out in November 2011 why that is the wrong direction to take:
Strategies to prevent pests becoming resistant are either not being correctly implemented, are failing, or are suffering from a combination of both. The result is more pesticide use rather than less. Throwing more GM at the problem may work in the short term, but the history of artificial pest control in agriculture has repeatedly shown the pests will win over the longer term.
The sooner we switch to agroecological farming techniques, such as avoidance of monocultures, long rotations and the use of natural predators to control pests, the better.
