Herbicide

According to a new study out of Washington State University, farmers of genetically engineered crops are dramatically increasing their use of herbicides. Researchers say farmers are spraying more in response the rise of so-called “superweeds.”

The new study analyzes 16 years of federal data on the nation’s corn, soybean and cotton fields. It finds growers with crops engineered to be herbicide resistant are now putting millions more pounds of weed killer on their fields than farmers who grow the non-modified variety.
