Research on Corn Pest Finds No Economic Benefit to GE Corn in the Northeast

(Beyond Pesticides, January 3, 2014) A recent study on the European corn borer (ECB), a major corn pest, finds no significant difference in yield between genetically engineered (GE)Bt (ECB-resistant) corn and non-GE corn in the Northeast, where pest pressure has decreased. Considering the high cost of GE corn, researchers determine that farmers will see no […]

Another Study Finds Rootworms Resistant to Genetically Engineered Corn

(Beyond Pesticides, September 3, 2013) For the past several years, corn rootworms have been widely reported to exhibit resistance to corn genetically engineered (GE) with the Bacillus thuringiensis (Bt) toxin. A new report by University of Illinois researchers found the resistant corn rootworm in two of the state’s counties significantly damaged by western corn rootworm. The increasing lack of efficacy of […]

Insecticide Sales Rise with Failure of GE Corn

(Beyond Pesticides, May 24, 2013) Insecticide sales have soared over the past year as target insects have developed resistance to crops genetically engineered (GE) to incorporate an insecticide. Contrary to industry claims that the technology would reduce pesticide use, crops like corn, engineered to protect against rootworm have been ineffective and farmers have begun applying […]

Corn Rootworm Resistance to Toxins in GE Crops, Says EPA

(Beyond Pesticides, January 25, 2013) The U.S. Environmental Protection Agency (EPA) has concluded that corn rootworm is now resistant to genetically engineered corn infused with a toxin derived from Bacillus thuringiensis, or Bt, in certain parts of the Corn Belt, casting doubt on the future viability of GE corn. The conclusion of the Insect Resistance Management […]
