Brazil farmers say GMO corn no longer resistant to pests

Genetically modified corn seeds are no longer protecting Brazilian farmers from voracious tropical bugs, increasing costs as producers turn to pesticides, a farm group said on Monday. Producers want four major manufacturers of so-called BT corn seeds to reimburse them for the cost of spraying up to three coats of pesticides this year, said Ricardo Tomczyk, president of Aprosoja farm lobby in Mato Grosso state. Experts in the United States have also warned about corn production prospects because of a growing bug resistance to genetically modified corn. Researchers in Iowa found significant damage from rootworms in corn fields last year.
