Farmers have long sought a soybean product that allowed for greater flexibility in over-the-top herbicide applications while providing sound agronomics and high yield potential. XtendFlex® soybeans were created to meet this need. Built on the proven Roundup Ready 2 Xtend® Technology, XtendFlex soybeans feature triple tolerance to glyphosate, dicamba and glufosinate.
To help get the most out of herbicide applications, starting clean is recommended. This can be done with a tillage pass or a burndown pass in a no-till situation. Adding a preemergence herbicide may be necessary for many farms to ensure season-long success.
After starting clean and utilizing a strong preemergence program, use midseason scouting to determine if there is a need for postemergence spray applications. With XtendFlex soybeans’ tolerance to glufosinate (group 10), glyphosate (group 9) and dicamba (group 4), farmers have a range of options to help manage tough-to-control and resistant weeds. Currently, some of the most difficult weeds to kill are Palmer amaranth, kochia, marestail, waterhemp, giant ragweed, lambsquarters and velvetleaf. When glyphosate is not the most effective option, an over-the-top application of dicamba or glufosinate in addition to an in-season application of a strong residual, like Warrant® herbicide or Warrant® Ultra herbicide, can provide strong control on these hard-to-kill weeds. Before tank mixing any herbicide with XtendiMax® herbicide with VaporGrip® Technology, a restricted use herbicide, refer to www.xtendimaxapplicationrequirements.com to view approved tank mixes. In addition, properly identifying weeds is a critical part of effective weed control. For help with identification, you can visit www.iwilltakeaction.com.
To minimize herbicide resistance and give your crops a competitive advantage over tough-to-control weeds, taking the long-term approach with effective herbicide management is the best strategy. With a new five-year registration for XtendiMax herbicide with VaporGrip Technology that must be used with VaporGrip® Xtra Agent or an equivalent Volatility Reduction Adjuvant (VRA), and the ability to use glufosinate with XtendFlex soybeans, keeping fields clean has never been more manageable.
