The Roundup Ready® Xtend Crop System is an advanced weed management system in the fight against resistant and tough-to-control weeds in soybeans and cotton. With advanced dicamba- and glyphosate-tolerant traits in soy and dicamba-, glyphosate- and glufosinate-tolerant traits in cotton, the Roundup Ready Xtend Crop System can help maximize weed control and the yield potential and quality of Roundup Ready 2 Xtend® soybeans and cotton with XtendFlex® technology.

Chris Kamienski, Monsanto technology development representative, and Lance Tarochione, CCA and Monsanto technical agronomist, review seed and herbicide product use and stewardship and weed control options in soybeans.
