Farmers planning to apply XtendiMax, Engenia, or Tavium to their dicamba-resistant soybeans have about one week remaining to make those herbicide applications. One of the requirements on the 2021 labels for over-the-top applications of herbicides containing dicamba was a cut-off date for applications. The last day these products can legally be applied to soybeans is June 30. The cut-off date for cotton is July 30.
Additional information can be found in the 2021 Chemical Weed Control for Field Crops, Pastures, Rangeland, and Noncropland, K-State publication SRP-1162.
The use of trade names is for clarity to readers and does not imply endorsement of a particular product, nor does exclusion imply non-approval. Always consult the herbicide label for the most current use requirements.
