The XtendFlex® system allows farmers to utilize an approved dicamba formulation as well as Liberty® and glyphosate. Beck’s Practical Farm Research (PFR)® data shows that using multiple effective SOAs in the pre-emerge resulted in fewer waterhemp for the post-emergence application to control. What is the relationship between the pre-emerge application and post-emergence application? If more money is spent on the pre-emerge application, can less be spent on the postemergence application? In 2021, the Beck’s PFR team set out to determine how the pre-emergence application impacted the post-emergence application and, conversely, how the post-emergence application impacted the pre-emergence application in the XtendFlex system. This study was designed to evaluate various programs in the XtendFlex system that target heavy, medium, and low waterhemp pressure.

XtendFlex® provides farmers the opportunity to utilize an approved dicamba formulation such as XtendiMax® or Engenia®, as well as Liberty® and glyphosate. Though some of our problematic weeds are resistant to glyphosate, there are several that glyphosate remains highly effective against. Glyphosate is also strong on many of the weeds that Liberty is weak on, such as cocklebur, velvetleaf, and grasses. Growth regulators such as Engenia or XtendiMax will be highly effective on broadleaf weeds but have no activity on grasses. The XtendFlex system allows farmers the opportunity to utilize Engenia or XtendiMax in the pre-emerge or early post-emergence application, providing short-term residual with no potential crop response. An additional option could include applying Liberty, separately, in-season to control any escaped weeds.
