Reminder that June 30th is the last day that Xtend soybeans can be treated with labeled dicamba herbicides (Xtendimax, Engenia, or Tavium) so plan accordingly. In addition, a reminder that all dicamba formulations require approved volatility reduction agent (or pH buffers).
Refer to the individual company’s website for above tankmixes and if additional drift reduction agent is needed when tankmixing.
Given the uncertainty of future EPA registration for these dicamba herbicides, existing product should be used before June 30th and do not expect to “carry it over” for the 2025 season.
