A recently published study from Iowa State University found that corn-destroying rootworms have evolved to be resistant to the Bt corn engineered to kill them.

Bt stands for Bacillus thuringiensis, the name of the genetically modified corn’s “donor” organism. Bt corn accounted for three-quarters of all corn planting in 2013.

Monsanto found guilty in France

A France court found Monsanto guilty on Monday of poisoning a French farmer. The farmer claims he suffered memory loss, headaches and stammering as a result from inhaling a Monsanto weedkiller in 2004. He argued that the weedkiller did not contain an adequate warning label.

This is the first time Monsanto has been found guilty in such a case. Past cases have failed due to the difficulty in linking symptoms to Monsanto’s products.

Monsanto has 19 locations in Iowa alone. Their seeds are used for about 90 percent of the soybeans and 70 percent of the corn grown in the U.S.

Earlier in the year, Monsanto faced criticisms after studies showed rootworms were becoming resistant to their pesticides, and widespread use of their herbicides was leading to the formation of superweeds.
