The cutoff date to apply dicamba (Engenia, Tavium, Xtendimax) postemergence in dicamba-tolerant soybeans planted in South Dakota was June 20, 2023.

Keep in mind, since dicamba does not have grass activity, an effective herbicide (examples include, Assure, Poast, Select) should have been co-applied to control grass weeds.

At this point, plan on making a sequential herbicide application to control grasses and other later emerging weeds. Again, the cutoff date to apply dicamba postemergence in dicamba-tolerant soybeans was June 20, 2023 in South Dakota.
