The EPA proposed to register Monsanto's herbicide dicamba for use on genetically modified crops of Roundup Ready 2 Xtend soybeans and Bollgard II XtendFlex cotton.

University of Tennessee Extension shares the most effective herbicides and tank mixes a grower can utilize as a burndown for marestail in soybeans and cotton.

Although horseweed can be controlled well with traditional auxin herbicides like 2,4-D or dicamba, Oklahoma State University has been exploring additional options that could increase the sustainability of auxin products for the future.

Monsanto Co. announced its commercial launch plans for its Roundup Ready2 Xtend soybeans after it received import approval in China, so the technology is now available in the U.S. and Canada in time for the 2016 season.

The 2014 harvest season has started and should be in high gear within the next week. As producers begin harvest they will need to be thinking about many management plans for next seasons crop. Herbicide programs and weed management strategies will be one of those topics that producers need to consider this fall as harvest wraps up this current growing season.

Now is the time to think about controlling summer annual weeds prior to seed set in cropping situations where this is possible.

Dicamba, Liberty and atrazine are the most effective options for controlling marestail post-emergence in corn, and atrazine alone may not kill larger plants.
