MDA Dicamba Herbicide 2021 Labels and Cutoff Date Info

The MDA has kept the June 30th cut-off date for the use of three dicamba products, XtendiMax, Engenia, and Tavium on soybeans in Minnesota for the 2021 growing season (dicamba cutoff date announcement). The federal label prohibits applications of these three dicamba products after June 30th to dicamba-tolerant soybeans. These formulations of dicamba are “Restricted Use Pesticides” (RUP) for retail sale to and for use only by Certified Applicators and are the only approved products for dicamba tolerant soybeans.

Each label for the new dicamba products specifies that applicators must attend dicamba specific training in order to use these products. Product manufacturers will provide training that meets the requirements of the label. Information about dicamba use and training is available on the product label and product manufacturer’s website at:

BASF Information on training can be found at

Bayer link for the mandatory training options is available at the following site  under the Training and Stewardship section

Corteva Agriscience recently announced that FeXapan is no longer being offered for sale.

Syngenta The training is available at the following website:

For 2021 training, the MDA has included a video presentation Dicamba post emergent weed control use on Dicamba Tolerant soybeans in 2021 (YouTube) that applicators are expected to view as part of mandatory training. Note that this video is a part of mandatory dicamba training and is not a substitute to the required training. If you are planning to use one of the RUP dicamba products, you must attend auxin/dicamba mandatory training offered by dicamba registrants (Bayer, BASF, or Syngenta).

Additional MDA Guidance on Cancelled Dicamba Products

Please find a question and answer guide from the MN Department of Agriculture here:

Mandate Issued on Dicamba Court Ruling

In an Ag Retailer Association Alert issued earlier this morning, they mentioned that until the 9th Circuit publishes a Mandate to enforce its order in the dicamba case, that the labels for the three products were still in effect.

ARA has now received a copy of the Mandate from the Court. Given this development, ARA has now advised that the safest conclusion to draw is that the registrations have been vacated and the products are no longer labeled. There may still be some legal recourse available to EPA and the manufacturers, but ARA has advised ceasing applications of Xtendimax, Engenia and Fexapan until advised by the registrants that it is legal to do so.

ARA has not yet received guidance from EPA.

Bayer will be updating this site with information. (ARA)
