A public interest group, representing environmental, public health, and organic farm interests, has asked the U.S. Environmental Protection (EPA) to deny an emergency request by Texas cotton growers to use a controversial pesticide on genetically engineered (GE) cotton to control weeds that are now resistant to the chemical they have been using, Roundup (glyphosate). Approximately 90% of cotton grown in Texas is genetically engineered or known as a genetically modified organism (GMO). The request, which comes through the Texas Department of Agriculture, seeks an allowance on 3 million acres for the highly toxic pesticide propazine, not registered for use on cotton.
