The Missouri Department of Agriculture has established cut-off dates for application of Engenia dicamba herbicide for the 2018 cotton and soybean seasons. These are part of a Section 24(c) Special Local Needs label for the BASF herbicide.
The state anticipates issuing similar Special Local Needs labels for XtendiMax with VaporGrip technology from Monsanto and FeXapan with VaporGrip technology from DuPont in the near future. The current SLN labels for those two herbicides expire Dec. 1, 2017.
Under the new SLN for Engenia, use of the herbicide on dicamba-tolerant soybeans and dicamba-tolerant cotton is prohibited after June 1, 2018, in Dunklin, Pemiscot, New Madrid, Stoddard, Scott, Mississippi, Butler, Ripley, Bollinger and Cap Girardeau counties.
Use of Engenia on dicamba-tolerant crops is prohibited after July 15, 2018, in the remaining counties.
During the application window, the products cannot be applied before 7:30 a.m. or after 5:30 p.m., according to MDA regulations.
Engenia is classified as a restricted-use pesticide and can only be sold to and used by certified applicators. Before purchase or use of the herbicide, certified applicators must complete a mandatory dicamba training program provided by the University of Missouri Extension. Training verification must be presented at the time of purchase.
Before each application, certified applicators must submit an online notice of application form.
