If an EPA proposal to approve Dicamba for us on genetically engineered soybeans and cotton is approved, growers would have a new tool at their disposal. EPA said weeds are becoming increasingly resistant to glyphosate-based herbicides, and the availability of dicamba will help reduce the spread of glyphosate-resistant weeds. CropLife America called the decision a milestone in helping farmers manage weeds resistant. CLA cites a decades-long history of safe use in the US and 25 other countries in corn, wheat, fallow and pastureland, conservation tillage acres, and even home uses. The comment period on the EPA proposal ends April 30.
